Red Sox to promote prospects Franklin Arias, Brandon Clarke to High-A Greenville

The Red Sox are promoting infield prospect Franklin Arias and pitching prospect Brandon Clarke from Low-A Salem to High-A Greenville, as was first reported by Andrew Parker of Beyond the Monster.

Arias, 19, is currently regarded by Baseball America as the No. 4 prospect in Boston’s farm system and the No. 72 prospect in the sport. The right-handed hitter batted a stout .346/.407/.397 with four doubles, nine RBIs, 15 runs scored, four stolen bases, six walks, and 12 strikeouts in 19 games (86 plate appearances) for Salem to open the season. He did not play in Sunday’s series finale against Hickory.

Among 93 qualified hitters in the Carolina League coming into play on Sunday, Arias ranked third in swinging-strike rate (6.1 percent), sixth in batting average, 11th in strikeout rate (14 percent), 13th in line-drive rate (29.2 percent), 21st in on-base percentage, 29th in wOBA (.401), 30th in OPS (.804), 34th in slugging percentage and wRC+ (128), and 46th in speed score, per FanGraphs.

On the other side of the ball, Arias has seen the vast majority of his playing time to this point in the season come at shortstop. With Salem, the 5-foot-11, 170-pounder logged 135 1/3 innings at short, where he committed just one error in 70 defensive chances. He also made one start at second base and two starts at DH.

A native of Venezuela, Arias originally signed with the Red Sox for $525,000 as an international free agent coming out of Caracas in January 2023. He put forth a strong professional debut in the Dominican Summer League that season, then caught fire in the Florida Complex League last year. To go along with being named the FCL’s 2024 MVP and top prospect, he was rewarded with a promotion to Salem in late July and was later recognized as Boston’s Minor League Baserunner of the Year.

“I definitely want to be the best player I can be. [But] I try to take it day to day and try not to look too far in the future,” Arias told The Boston Globe’s Alex Speier (through a translator) earlier this month. “I feel that’s what helped me get that MVP last year, and I think if I can take that day-to-day approach this year, I can have some similar results.”

Arias, who does not turn 20 until November, also told Speier that he is aiming to make it to Double-A Portland or even Triple-A Worcester before his age-19 season draws to a close. If he were to receive a promotion to Portland at some point this winter or fall, he would join Roman Anthony (2023) and Xander Bogaerts (2012) as the two most recent Red Sox prospects to reach the Double-A level as teenagers.

In Greenville, Arias is slated to join a middle infield mix that already includes the likes of Marvin Alcantara, Nazzan Zanetello, Fraymi De Leon, and Justin Riemer (on the injured list). It would not be terribly surprising if he emerged as the Drive’s primary shortstop moving forward, though he could spend additional time at second base to get others reps at short.

Clarke, meanwhile, is not yet ranked by Baseball America as one of Boston’s top pitching prospects, though that will likely be changing soon. The 22-year-old left-hander was selected by the Red Sox in the fifth round (148th overall) of last summer’s draft out of State College of Florida, Manatee-Sarasota. He forewent his commitment to transfer to South Carolina by signing for $400,000, but did not pitch for an affiliate after putting pen to paper.

Clarke, instead, waited until April 10 of this year (his 22nd birthday) to make his professional debut. The Virginia native then posted a 0.93 ERA (1.20 FIP) with 17 strikeouts to just two walks in his first three starts (9 2/3 innings) for Salem. He only gave up two hits in that stretch as two of his three outings to kick off the 2025 campaign were both scoreless and hitless.

Among the 118 Caroline League pitchers who entered Sunday with at least nine innings under their belts early on, Clark ranked first in FIP and xFIP (1.55), second in strikeout rate (47.2 percent) and groundball rate (68.8 percent), batting average against (.061), and WHIP (0.41), third in line-drive rate (6.3 percent) and swinging-strike rate (21.3 percent), 13th in ERA, and 17th in walk rate (5.6 percent), per FanGraphs.

Listed at 6-foot-4 and 220 pounds, Clarke stood out in spring training not just because of his large stature, but because of his arsenal as well. As highlighted in his SoxProspects.com scouting report, the athletic lefty throws from a three-quarters arm slot and incorporates a high leg kick into his delivery. He operates with a four-pitch mix that consists of a 96-99 mph fastball that tops out at 100 mph, an 87-90 mph slider, an 81-85 mph sweeper, and an 87-89 mph changeup that is still considered a work in progress.

Much like Arias, Clarke is in line to face more advanced competition at the High-A level with this promotion. Presumably taking the place of fellow southpaw Hayden Mullins (promoted to Portland) in Greenville’s starting rotation, Clarke will join a talented pitching staff headed by 2024 second-round draft pick Payton Tolle, Juan Valera, and Jedixson Paez. He will likely make his Drive debut in the team’s upcoming series against the Asheville Tourists at Fluor Field.

Red Sox OF prospect Jhostynxon Garcia recognized for productive week with Double-A Portland

Red Sox outfield prospect Jhostynxon Garcia was named to MLB Pipeline’s Prospect Team of the Week for April 14-20 on Monday.

Garcia, Boston’s No. 6 prospect according to MLB Pipeline, appeared in five of Double-A Portland’s six games on the road against the Hartford Yard Goats this past week. The right-handed hitting 22-year-old went 9-for-19 (.474) with two doubles, one home run, five RBIs, five runs scored, one stolen base, three walks, and two strikeouts.

Batting out of the three-hole in all five games he got into at Hartford’s Dunkin’ Park, Garcia doubled and drove in two runs on Tuesday, recorded three hits and drove in two runs on Wednesday, singled twice on Thursday, sat on Friday, went hitless on Saturday, and homered for the first time this season in Sunday’s series finale.

Through his first 11 games for the Sea Dogs in 2025, Garcia is batting .308/.429/.462 with three doubles, one home run, six RBIs, seven runs scored, two stolen bases, nine walks, and 11 strikeouts over 49 plate appearances. Among 84 qualified Eastern League hitters, he ranks eighth in on-base percentage, ninth in walk rate (18.4 percent) and batting average, 10th in wOBA (412), 12th in OPS (.890) and wRC+ (156), 15th in line-drive rate (28.6 percent), 20th in slugging percentage, 29th in swinging-strike rate (10.1 percent), 32nd in strikeout rate (22.4 percent), and 34th in isolated power (.154), per FanGraphs.

On the other side of the ball, Garcia has seen all his playing time to this point in the season come in center field. The 6-foot, 215-pounder has logged 99 errorless innings in center for Portland thus far, recording one outfield assist in the process of doing so. He also has past experience in the corners, with MLB Pipeline grading his field tool as a 50 and his arm tool as a 60 on the 20-80 scouting scale.

Aptly nicknamed “The Password” because of his hard-to-spell first name, Garcia originally signed with the Red Sox for $350,000 as an international free agent coming out of Venezuela in July 2019. The San Fernando de Apure native was a lesser-known prospect at this time a year ago, but he put together a breakout 2024 campaign that saw him soar from Low-A all the way to Double-A while clubbing an organizational-leading 23 home runs in 107 games.

Garcia, the older brother of Red Sox catching prospect Johanfran Garcia, was added to Boston’s 40-man roster last November to receive protection from the Rule 5 Draft and subsequently took part in his first major league camp this spring. Though he was not competing for an Opening Day roster spot, the elder Garcia still had the chance to showcase himself (at the Spring Breakout and Futures at Fenway South games) and impress manager Alex Cora in Fort Myers.

“Good swing,” Cora said of Garcia when speaking with reporters (including MassLive.com’s Christopher Smith) back in February. “He moves in the outfield, too. He’s a big dude, but he moves. … So he’s impressive.”

Garcia, who does not turn 23 until December, told Smith in camp that his goal for the season was “to have at least a couple of games toward the end of the year in the big leagues.” For as lofty as that may seem, it could become feasible if Garcia continues to produce with Portland and forces his way up to Triple-A Worcester before long.

What does Red Sox prospect Justin Gonzales have in store for 2025?

After a strong debut season in the Dominican Summer League last year, what does power-hitting Red Sox prospect Justin Gonzales have in store for 2025?

Hailing from the Dominican Republic himself, Gonzales entered the professional ranks at just 17 by signing with the Red Sox for $250,000 as an international free agent last January. He received the sixth-largest bonus in Boston’s 2024 signing class but was undoubtedly the top offensive performer between the club’s two DSL affiliates.

In 47 games for DSL Red Sox Blue and Red, Gonzales batted a stout .320/.391/.517 (140 wRC+) with 11 doubles, four triples, five home runs, 29 RBIs, 29 runs scored, eight stolen bases, 19 walks, and 20 strikeouts over 192 plate appearances. The right-handed hitting slugger was named a DSL All-Star as he helped DSL Red Sox Red secure the organization’s first Dominican Summer League title since 2016. He was also recognized as Boston’s 2024 Latin Program Position Player of the Year.

“He’s a big, strong kid already who has a good feel to hit, a good feel for contact,” said Red Sox assistant general manager Eddie Romero, who described Gonzales as “a big, strong animal” when speaking with MassLive.com’s Christopher Smith earlier this week. “So we just need to make a couple of minor adjustments on his launch angles and things like that. And those really low line drives, we can start getting him to elevate it a little bit more and more and find some gaps.”

Gonzales, who turned 18 in December, arrived in Fort Myers for his first spring training in the United States early last month. The towering first baseman/outfielder has taken well to instruction and already looks larger than his listed height and weight of 6-foot-4 and 210 pounds. He was a late addition to Boston’s Spring Breakout roster on March 13, as he took the place of Allan Castro. Though he struck out in his lone at-bat against the Rays in Port Charlotte that night, he showed flashes of his power potential in the following afternoon’s “Futures at Fenway South” showcase against the Twins at JetBlue Park.

As highlighted by SoxProspects.com’s director of scouting, Ian Cundall, Gonzales pinch-hit and took over for starting right fielder Miguel Bleis midway through the exhibition. He then grounded out to short in his first at-bat, ripped a single through the left side of the infield in his second at-bat, and crushed a no-doubt solo home run over the faux Green Monster in his third and final at-bat.

Gonzales is currently regarded by SoxProspects.com as the No. 19 prospect in Boston’s farm system. MLB Pipeline has him four spots higher at No. 15, while Baseball America does not yet have him ranked. He is in extended spring training right now and is expected to play in the rookie-level Florida Complex League once that season gets underway next month. MLB.com’s Jonathan Mayo, Jim Callis, and Sam Dykstra recently predicted that Gonzales will lead the FCL in home runs this year with 12 in 54 games.

“His combination of raw power and swing decisions will make him one of the best first-base prospects in baseball,” they wrote of Gonzales, who also figures to see playing time in the outfield moving forward after making 14 starts in right and two starts in center last season. He does, after all, possess “plus-plus” arm strength that MLB Pipeline grades as a 70 on the 20-80 scouting scale.

“He’s really intriguing overall,” Romero said. “I know that we’ve played him some in center field throughout the spring, and we’ll do that in extended some and kinda go from there. But give him every chance. If not, he can definitely profile in a corner.”

Former Red Sox catching prospect Kyle Teel (part of Garrett Crochet trade) named International League Player of the Week

Former Red Sox catching prospect Kyle Teel has been named the International League Player of the Week for the week of March 28-30, Minor League Baseball announced on Monday.

One of four prospects traded to the White Sox for ace left-hander Garrett Crochet in December, Teel has gotten his 2025 season off to a tremendous start. Appearing in all three of Triple-A Charlotte’s games against Gwinnett over the weekend, the left-handed hitter went 6-for-12 (.500) with one double, two home runs, nine RBIs, four runs scored, two walks, and two strikeouts as the Knights swept the Stripers.

Teel batted cleanup in all three contests for the Knights at Charlotte’s Truist Field, making two starts at DH and one start at catcher. The 23-year-old belted his first homer of the season on Friday, finished a triple shy of the cycle while driving in a career-high six runs on Saturday, and reached base twice on Sunday.

Originally selected with the 14th overall pick in the 2023 draft out of Virginia, Teel is currently regarded by Baseball America as the No. 4 prospect in Chicago’s farm system and the No. 51 prospect in the sport. After slashing .288/.386/.433 with 23 doubles, 13 home runs, 78 RBIs, 88 runs scored, 12 stolen bases, 68 walks, and 116 strikeouts in 112 games (505 plate appearances) between Double-A Portland and Triple-A Worcester last season, the New Jersey native was traded by the Red Sox to the White Sox for Crochet on December 11 alongside fellow prospects Braden Montgomery, Chase Meidroth, and Wikelman Gonzalez.

All four were in major league camp with the White Sox this spring at Camelback Ranch in Glendale, Ariz. Teel, in particular, impressed offensively by going 6-for-19 (.316) with one double, two home runs, six RBIs, five runs scored, four walks, and four strikeouts in 14 Cactus League games. On the other side of the ball, the athletic 6-foot, 210-pound backstop logged 34 2/3 error-less innings behind the plate but did not have much of a chance to show off his arm strength as he only (unsuccessfully) dealt with one base stealer.

As things stand in Charlotte, Teel is slated to split catching duties with another top 100 prospect in Edgar Quero. The plan out of the gate, as highlighted by Jeff Cohen of FutureSox.com, is for Teel and Quero to both be in the Knights’ lineup on a nightly basis, with the former serving as the DH when the latter is behind the plate and vice-versa.

While the case can be made that Teel and Quero are competing to be the backstop of the future for the White Sox, they are both currently behind Korey Lee and Matt Thaiss on Chicago’s catching depth chart. Still, the expectation is that, at the very least, Teel will make his big league debut at some point before the 2025 campaign ends. He could speed that timeline up if he continues to punish International League pitching the way he has been early on.

Red Sox OF prospect Enddy Azocar ‘has caught some attention’ this spring

The Red Sox have several young minor leaguers who are slated to make the jump from the Dominican Summer League to the Florida Complex League this upcoming season.

Enddy Azocar, an 18-year-old outfielder from Venezuela, is among them.

Azocar, who turned 18 last month, originally signed with Boston for $40,000 as an international free agent in January 2024. The Puerto La Cruz native made his professional debut in the Dominican Summer League five months later.

In 31 regular-season games for DSL Red Sox Red, Azocar batted .266/.397/.309 (107 wRC+)with two doubles, one triple, 11 RBIs, 17 runs scored, two stolen bases, 18 walks, and 15 strikeouts over 116 plate appearances. The right-handed hitter then went 2-for-7 (.286) in a pair of playoff contests as DSL Red Sox Red claimed the organization’s first Dominican Summer League title since 2016 and second overall.

On the other side of the ball, Azocar saw the vast majority of his playing time last year come in left field. The 6-foot-2, 168-pounder (listed weight) logged a team-high 219 innings in left for DSL Red Sox Red without recording an error or assist in 60 defensive chances. Elsewhere, he committed one error in four chances across 14 innings in right field.

As part of his first spring training in Fort Myers, Azocar has gotten some positive exposure. In addition to what he has shown on the backfields, he was featured in last Friday’s “Futures at Fenway South” showcase against prospects from the Twins organization at JetBlue Park. Though he went hitless in the game itself, the overall body of work this spring has nonetheless been encouraging.

“Enddy has had a great spring so far and has caught some attention,” Red Sox assistant general manager Eddie Romero said via email. “His frame will allow for plenty of strength and he’s already 6-foot-2 at 18 years old. He did a great job in the offseason of getting stronger and he’s only starting to fill that frame out. Enddy showed a polished approach in the DSL with more walks than strikeouts.

“So far this spring, we’re seeing a lot of hard contact with multiple 100+ [mph exit velocities],” Romero continued. “Will be very interesting to see him develop this year.”

Azocar is not currently regarded by SoxProspects.com as one of the premier prospects in Boston’s farm system, though it would not be surprising if he cracked the back end of their top-60 rankings at some point this summer after the 2025 Florida Complex League season begins in early May.

Kleyver Salazar among 7 unranked prospects to make Red Sox ‘Spring Breakout’ roster

On Thursday, the Red Sox unveiled their roster for their upcoming ‘Spring Breakout’ matchup against the Rays next week.

While Boston will be sending a plethora of top talents from a loaded farm system to Port Charlotte for the second annual prospects showcase next Thursday, several unheralded Red Sox minor-leaguers will be making the trip from Fort Myers as well.

Of the 27 players on the Red Sox ‘Spring Breakout’ roster, seven are not currently ranked among the organization’s top 30 prospects by MLB Pipeline. Of those seven, 18-year-old catcher Kleyver Salazar stands out as someone who has yet to suit up for a full-season affiliate.

Salazar, who turns 19 in May, is the younger brother of former Red Sox (and current Cardinals minor-leaguer) Johnfrank Salazar. The native Venezuelan originally signed with Boston for $175,000 as an international free agent in January 2023 and made his professional debut in the Dominican Summer League before moving up to the Florida Complex League in 2024.

In 49 games (183 plate appearances) for the FCL Red Sox, Salazar batted .226/.333/.374 with seven doubles, two triples, four home runs, 31 RBIs, 22 runs scored, two stolen bases, 25 walks and 40 strikeouts. The right-handed hitter ended his season on a particularly high note by slashing .313/.389/.500 with three home runs and 15 RBIs over 20 games (72 plate appearances) in July.

Though a .708 OPS (95 wRC+) on the year is far from eye-popping, Salazar did rank 21st in isolated power (.148) and 32nd in walk rate (13.7 percent) among 71 qualified FCL hitters, per FanGraphs. He also led the way in fly-ball rate (55.7 percent), which suggests that he may have gotten under the ball quite a bit.

Defensively, Salazar split his playing time on the field between catcher and first base last year. The 6-foot-1, 187-pound backstop logged a team-high 168 2/3 innings behind the plate for the FCL Red Sox, allowing eight passed balls and throwing out 14 of 49 possible base stealers. In 16 starts as a first baseman, he committed just two errors in 98 chances.

Salazar joins Brooks Brannon and Ronald Rosario to make up the catching contingent on Boston’s ‘Spring Breakout’ roster. He is currently projected by SoxProspects.com to return to the FCL for the start of the 2025 season, though his assignment could change to Low-A Salem if fellow backstop Johanfran Garcia (who underwent season-ending ACL surgery last May) is not fully ready to go when camp breaks next month.

Red Sox prospect Mikey Romero catching eye of Alex Cora in spring training

Before Wednesday afternoon’s Grapefruit League contest against the Rays at JetBlue Park, Red Sox manager Alex Cora was asked about which prospects outside of The Big Three of Roman Anthony, Kristian Campbell, and Marcelo Mayer have caught his eye so far this spring.

“Mikey Romero, the last three, four days,” Cora quickly responded. “He’s a good player, a really good player. Good at-bats, good defender. Mikey Romero is a good player. We just got to get him healthy. He did everything this offseason to put himself in good shape. He’s a lot stronger now. This is the first time I’ve had a look consistently and I like him as a player. … Good instincts, really good instincts.”

Romero, who turned 21 in January, is not in major-league camp with the Red Sox in Fort Myers but has appeared in three Grapefruit League games thus far. The left-handed hitting infielder has gone 2-for-3 with one RBI, one run scored, and one walk while seeing playing time at second base and shortstop.

Originally selected by the Red Sox with the 24th overall pick in the 2022 draft out of Orange Lutheran High School (Calif.), Romero has already endured plenty on and off the field to this point in his professional career. The San Diego forwent his commitment to Louisiana State by signing with Boston for an under-slot $2.3 million and made a positive first impression in his brief pro debut between the rookie-level Florida Complex League and Low-A Salem.

Romero’s first full season in the professional ranks was not nearly as memorable. He opened the 2023 campaign on the injured list due to a stress reaction in his lower back that he suffered during spring training and did not return to action until late June. He then spent the better part of the next two months rehabbing with the FCL Red Sox and Salem before being promoted to High-A Greenville in mid-August. Just three games into his first stint with the Drive, however, Romero sustained a stress fracture that cost him the remainder of the year.

Altogether, Romero struggled to a .214/.294/.286 slash line with five doubles, two triples, 13 RBIs, 15 runs scored, two stolen bases, 14 walks, and 25 strikeouts over 34 total games (144 plate appearances) across three levels in 2023. He dropped from No. 6 to No. 16 in Baseball America’s Red Sox prospects rankings heading into 2024, though more pressing issues were at hand for Romero on a personal level.

On Valentine’s Day last year, Romero’s father — Mike Romero — passed away following a lengthy battle with tongue cancer. Mikey Romero then reported to Fort Myers for camp but was sidelined by back spasms and missed roughly the first month of the 2024 season as a result. He completed a three-game rehab assignment in the FCL before re-joining Greenville on May 15. From that point forward, he looked like a different hitter.

Romero consistently lined the ball in the air in the process of batting .271/.312/.509 with 20 doubles, four triples, 10 home runs, 40 RBIs, 40 runs scored, one stolen base, 16 walks, and 58 strikeouts over 59 games (276 plate appearances) for Greenville. He was named the South Atlantic League Player of the Month for July and subsequently received a promotion to Double-A Portland in late August. He then closed out the season by slashing .243/.257/.543 with three doubles, six home runs, 12 RBIs, 11 runs scored, two walks, and 25 strikeouts in 16 games (74 plate appearances) for the Sea Dogs.

Between the FCL, Greenville, and Portland in 2024, Romero batted .271/.312/.509 with 24 doubles, four triples, 16 home runs, 53 RBIs, 54 runs scored, one stolen base, 18 walks, and 84 strikeouts over 78 games (362 plate appearances). Among the 31 Red Sox minor-leaguers who made at least 360 trips to the plate last year, Romero most notably ranked second in isolated power (.238), fourth in slugging percentage, ninth in OPS (.821) and wRC+ (127), and 11th in batting average and wOBA (.366), per FanGraphs.

On the other side of the ball, Romero saw most of his playing time last season come at either second base or shortstop. With Portland in particular, he made 14 starts at shortstop and just one at second base, committing two errors in 52 total defensive chances. He is listed at 5-foot-11 and 175 pounds but currently weighs in at around 205-207 pounds as he continues to add muscle to his athletic frame.

In addition to shedding light on his strength gains, Romero looked back on a season that netted him 2024 SoxProspects.com Comeback Player of the Year honors when speaking with Rob Bradford on Audacy’s ‘Baseball Isn’t Boring’ Podcast earlier Wednesday.

“Last year was a really good year for me, finishing at Double-A,” Romero said. “You can look at the stats and see that it was a great year. I think just being healthy, and playing — towards the end of the season — every day, it was great. To get to play for [Iggy Suarez at High-A and Chad Epperson at Double-A], I learned so much. Being with the older guys once I got to Double-A was pretty cool, to just pick their brains and see how they go about their business.”

Romero enters 2025 ranked by Baseball America as the No. 18 prospect in Boston’s farm system. He is projected to break camp with Portland next month and is aiming to carry over the momentum he gained last year into the upcoming season. Simultaneously, he is looking to take advantage of the opportunity he is getting by playing in big-league spring training games for the first time and sharing a dugout with established veterans like Alex Bregman.

“It’s pretty awesome,” said Romero. “Whether I’m starting or whether I’m backing up, coming in in the sixth inning. It’s just cool to be in the same dugout as a lot of these guys. Bregman, just a bunch of these guys. It’s really cool. Getting to see how they go about their business, not only for me playing but also just to be around the caliber of players we have in this clubhouse. It’s pretty cool. I’m taking advantage of it and I’m excited.”

Though the past year has undoubtedly been tough for Romero, he has been able to maintain a positive mindset thanks in part to his faith and the implementation of routines that he expects will keep him healthy. He also got married in November and is looking forward to what lies ahead in both his life and playing career.

“Starting off the year with my dad passing was, obviously, tough on my family, on me,” Romero said. “But I think the Lord was gracious to me. I got to play a full year healthy, I had a pretty damn good year, and to get to the cherry on top I got to marry my now-wife. Going into 2025, there’s no better feeling to have her here with me as well as to be healthy and to be getting spring training reps and just to be around the guys.”

Red Sox to sign former Angels two-way prospect to minor-league deal

The Red Sox have signed free agent left-hander Erik Rivera to a minor-league contract, as was first reported by Hunter Noll of Beyond the Monster. Rivera himself appears to have confirmed the signing on his Instagram account.

Rivera is a former 2019 fourth-round draft pick of the Angels out of the Puerto Rico Baseball Academy. The 23-year-old Caguas native was taken 121st overall and forewent his commitment to Florida International by signing with Los Angeles for $597,500.

A two-way player coming out of high school, Rivera signed with the Angels as an outfielder and batted .208/.313/.264 with four doubles, nine RBIs, eight runs scored, nine walks, and 31 strikeouts over 21 games (83 plate appearances) in the 2019 rookie-level Arizona League. His first full professional season was wiped out due to the COVID-19 pandemic in 2020 and he emerged as a full-time pitcher beginning in 2021.

Rivera entered the 2021 season ranked by Baseball America as the No. 14 prospect in Los Angeles’ farm system. The lefty made his professional pitching debut at Low-A Inland Empire that May but then suffered a sprained UCL in his left elbow that ultimately required surgery. As a result, he missed the remainder of the 2021 campaign and all of 2022 before making his way back to the mound in August 2023. He closed out the year by forging a 4.09 ERA (5.90 FIP) with 16 strikeouts to 15 walks in seven total outings (11 innings) between the Arizona Complex League and High-A Tri-City.

Rivera returned to Tri-City for the start of the 2024 season and posted a 3.31 ERA (4.94 FIP) with 39 strikeouts to 20 walks over 10 appearances (eight starts) spanning 35 1/3 innings in which opposing hitters batted .213 against him. The southpaw was released by the Angels in late July and spent the remainder of the year in free agency. Most recently, he enjoyed a productive offseason back on his home island by pitching to a 1.04 ERA (0.86 WHIP) with 21 strikeouts to 10 walks in 16 relief appearances (17 1/3 innings) for the Leones de Ponce of the Puerto Rican Winter League.

Listed at 6-foot-2 and 200 pounds, Rivera has been described as having a smooth and athletic delivery. In the past, he has reached 95 mph with his fastball which typically sits in the lower-90s. He has also featured an upper-70s curveball that resembled a slider and a lower-80s changeup with fade, per his July 2021 Baseball America scouting report.

Rivera, who turns 24 in April, should provide the Red Sox with additional pitching depth from the left side in the lower minors to open the 2025 season. It remains to be seen what affiliate he will break camp with later this spring, though Low-A Salem or High-A Greenville would appear to be the most likely destinations.

Who is Yosander Asencio? Switch-hitting Red Sox OF prospect posted .834 OPS in 2024 Florida Complex League

When searching for under-the-radar Red Sox prospects who could break out to some degree in 2025, infielder-turned-outfielder Yosander Asencio is one name that may be worth monitoring.

Not to be confused with Vladimir Asencio, Boston’s top international signing last winter, Yosander originally signed with the Red Sox for $85,000 as an international free agent coming out of the Dominican Republic in January 2022. The Bajos de Haina native spent the first two seasons of his professional career in the Dominican Summer League, where he slashed .295/.458/.415 over 78 total games (308 plate appearances), before making his stateside debut in 2024.

Asencio, who turned 20 in November, enjoyed a solid season offensively in the Florida Complex League. The switch-hitter batted .271/.393/.441 with seven doubles, two triples, three home runs (the first three of his pro career), 27 RBIs, 23 runs scored, six stolen bases, 25 walks, and 48 strikeouts in 43 games (145 plate appearances) for the FCL Red Sox. That includes a .255/.377/.434 line from the left side of the plate and a .417/.533/.500 line from the right side.

Among the 82 FCL hitters who made at least 140 trips to the plate last year, Asencio ranked 14th in isolated power (.169), 17th in walk rate (17.2 percent), 20th in slugging percentage, 21st in OPS (.834), 22nd in wOBA (.403) and wRC+ (128), 25th in speed score (7.5), 28th in on-base percentage, and 33rd in batting average. Conversely, he posted the fifth-highest swinging-strike rate (21.8 percent) and ninth-highest strikeout rate (33.1 percent), per FanGraphs.

Defensively, Asencio saw playing time at all three outfield positions with Boston’s FCL affiliate. The 5-foot-11, 160-pounder (listed height and weight) logged a team-leading 116 2/3 innings in left, 90 1/3 innings in right, and 35 innings in center. He recorded three outfield assists without committing a single error in 53 total chances.

Asencio is not currently regarded by publications such as Baseball America or MLB Pipeline as one of the top prospects in Boston’s farm system. However, SoxProspects.com projects him to open the 2025 season at Low-A Salem, which would represent an opportunity for him to get his name out there more if he continues to produce the way he has been.

Red Sox two-way prospect identified as potential 2025 breakout candidate

The Red Sox have several prospects who could break out in 2025, including those who have yet to make their professional debuts.

Conrad Cason, the club’s eighth-round selection in last summer’s draft, is one such name to watch. MLB.com’s Jim Callis, Jonathan Mayo, and Sam Dykstra recently identified the two-way talent as a potential breakout candidate within Boston’s farm system this year.

Cason, 18, was taken with the 237th overall pick in the 2024 draft out of Greater Atlanta Christian School. The Georgia native forwent his commitment to Mississippi State by signing with the Red Sox for a well over-slot $1.25 million. However, he did not play for one of Boston’s minor-league affiliates after putting pen to paper at Fenway Park on July 29.

To cap off his high school career at Greater Atlanta Christian, Cason shined as both a pitcher and a shortstop en route to earning Gatorade Player of the Year honors in Georgia last spring. On the mound, the right-hander posted a 0.48 ERA with 99 strikeouts over 43 2/3 innings. At the plate, the right-handed hitter batted .364/.519/.545 with three home runs, 28 RBIs, 32 runs scored, and 16 stolen bases.

As a senior, Cason flashed a three-pitch mix that consisted of a 93-95 mph fastball that reached 97-98 mph, a low-80s split-grip changeup, and a tight slider with similar velocity, per his MLB.com scouting report. The athletic 6-foot-1, 190-pounder also possesses solid speed and power potential, which he put on display while showcasing his abilities as a shortstop at the MLB Draft Combine.

Though most teams preferred him as a pitcher during the pre-draft process, the Red Sox will provide Cason with an avenue to develop on both sides of the ball at the outset of his pro career. Devin Pearson, Boston’s director of amateur scouting, made that much clear when speaking with reporters (including MassLive.com’s Chris Cotillo) shortly after Cason was drafted.

“Our group was actually a little bit split on it. We had some guys that liked him better as a pitcher and other guys that liked him better as a hitter,” Pearson said. “On both sides, you have an elite athlete who can throw 100 mph and hit balls very far. We will take that bet and see where he best fits but we’re going to develop him as a two-way player.”

Cason, who does not turn 19 until August, comes into the new year ranked by MLB Pipeline as the No. 15 prospect in Boston’s farm system. He is currently projected by SoxProspects.com (which has him ranked 16th) to open the 2025 minor-league season at Low-A Salem. How his workload is managed will presumably come into focus closer to Opening Day.
