How did Red Sox relief prospect Isaac Stebens fare in 2024?

Despite dealing with his fair share of command and control issues throughout the year, Red Sox pitching prospect Isaac Stebens still turned in a solid 2024 season.

Stebens, who just turned 23 last month, was selected by the Red Sox in the 16th round of the 2023 draft out of Oklahoma State. The Stillwater native received an at-slot $150,000 signing bonus that July but did not pitch for a minor-league affiliate after putting pen to paper. He instead had to wait until last April to make his professional debut.

Stebens opened the 2024 campaign at Low-A Salem but was not there long. The right-hander allowed just three runs (one earned) on seven hits, four walks, and 14 strikeouts in six relief appearances (11 innings) before receiving a promotion to High-A Greenville on April 25.

In 29 outings for Greenville, Stebens posted a 3.68 ERA (3.77 FIP) with 73 strikeouts to 31 walks over 51 1/3 innings of relief in which opposing hitters batted .228 against him. That includes a 0.53 ERA (2.62 FIP) in his final 12 appearances (17 innings) of the season dating back to July 14.

Altogether, Stebens forged a 3.18 ERA (3.58 FIP) with 87 strikeouts to 35 walks in 35 total relief appearances (62 1/3 innings) between Salem and Greenville last year. Among 39 Red Sox minor-leaguers who threw at least 60 innings, Stebens ranked third in strikeout rate (31.3 percent), fourth in strikeouts per nine innings (12.56), 11th in FIP, 12th in ERA, 14th in xFIP (3.79), and 17th in batting average against (.220). On the opposite end of the spectrum, he ranked 33rd in walk rate (12.6 percent) and 34th in walks per nine innings (2.49), per FanGraphs.

Listed at 6-foot and 194 pounds, Stebens featured four pitches last season, per his SoxProspects.com scouting report. Throwing from a low three-quarters arm slot, the righty sat between 92-94 mph and topped out at 95 mph with his fastball while also mixing in an 83-84 mph slider, a 78-80 mph curveball, and an 84-86 mph changeup.

As he recently explained to hosts Andrew Parker and Chris Henrique on Beyond The Monster’s ‘To the Show We Go’ podcast, Stebens implemented three new pitches into his arsenal last year after primarily relying on his fastball at Oklahoma State. Because of that, the 2024 season served as somewhat of an adjustment period for him.

“I wouldn’t say it was seamless. It was definitely a grind,” Stebens said. “There was no backlash on my part. I was all about it. I knew it was what needed to be done. But going from throwing one pitch that’s pretty good to adding three more, it definitely increased my walk rate just because I didn’t know how to control those yet. So we’re still learning those. Hopefully, having a long career, I’m going to nail some of those things down.

“I was able to strike out more in less innings than I did at OSU [in 2023], so a lot of good things,” he continued. “But it was definitely a grind learning those new pitches, just utilizing them more than anything. I had three of the four I have now going into the year but the usage rate went from 85 percent fastball and 10 percent slider and five percent changeup to about 40-20-20, so it was a big difference to split up that 80 percent.”

Stebens is not currently regarded by publications such as Baseball America or MLB Pipeline as one of the top pitching prospects in Boston’s farm system. SoxProspects.com projects him to return to Greenville for the start of the upcoming season, though he made clear in his conversation with Parker and Henrique that he, at the very least, wants to make it to Double-A Portland before the end of 2025.

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.

Why Juan Valera took the biggest leap of any Red Sox pitching prospect in 2024

The case can be made that Juan Valera took the biggest leap of any Red Sox pitching prospect in 2024.

Originally signed for $45,000 as an international free agent coming out of the Dominican Republic in April 2023, Valera posted a 5.93 ERA (4.67 FIP) over 27 1/3 innings as part of his professional debut in the Dominican Summer League last year. As such, the young right-hander came into the 2024 season with very little fanfare.

Transitioning from the Dominican Summer League to the Florida Complex League, Valera impressed out of the gate in his stateside debut. The 18-year-old forged a 1.79 ERA (3.25 FIP) with 40 strikeouts to 14 walks in 11 outings (nine starts) spanning 40 1/3 innings for the FCL Red Sox. He held opposing hitters to a .128 batting average and leveraged his performance into a promotion to Low-A Salem in late July.

The trade deadline passed shortly thereafter, but not before Valera saw three teammates (fellow teenage righties Gilberto Batista, Ovis Portes, and Yeferson Vargas) get moved elsewhere. The Red Sox, however, elected to hold onto Valera, who proceeded to post a 2.35 ERA (3.54 FIP) with 28 strikeouts to 14 walks in seven starts (23 innings) for Salem to close out the year. Opposing hitters in the Carolina League batted just .120 against him in that stretch.

Altogether, Valera pitched to a 1.99 ERA (3.36 FIP) with 68 strikeouts to 28 walks in 18 appearances (16 starts) spanning 63 1/3 innings between the FCL and Salem this past season. Among the 39 Red Sox minor-leaguers who threw at least 60 innings in 2024, Valera ranked first in ERA, batting average against (.125), WHIP (0.85), line-drive rate (10.3 percent), and groundball rate (56.6 percent), fifth in swinging-strike rate (15.9 percent), eighth in FIP, 12th in strikeout rate (27.9 percent), and 13th in xFIP (3.76), per FanGraphs.

As far as post-season accolades are concerned, Valera was recognized as a 2024 Florida Complex League All-Star by Minor League Baseball. He was also named a 2024 SoxProspects.com All-Star and the 2024 SoxProspects.com Pitcher of the Year.

Standing at 6-foot-3 and around 225 pounds, Valera throws from a high three-quarters arm slot and utilizes a side-step delivery. This past season, the projectable hurler operated with a four-pitch mix that consisted of a 93-96 mph fastball that reached 99 mph, an 85-88 mph slider that featured 10-to-4 break, an 82-85 mph sweeper, and an 89-92 mph changeup that is still viewed as a work progress.

Lauded by club officials for his strong work ethic and teachability, Valera is currently regarded by SoxProspects.com as the No. 19 prospect in Boston’s farm system, which ranks ninth among pitchers in the organization. MLB Pipeline has the righty ranked 20th on its top 30 Red Sox prospects list while Baseball America has him unranked, though that will likely change soon.

“We’re super high on this kid,” Red Sox director of pitching Justin Willard said of Valera when speaking with The Boston Globe’s Sarah Barber back in August. “He’s starting to get to some pretty cool shapes from a pitch-design standpoint. We’re very excited about this kid, and he’s only continued to go out there and kind of hammer the things that he needs to for his long-term development as well.”

Valera, who turns 19 in May, is projected by SoxProspects.com to return to Salem for the start of the 2025 minor-league season. He should, however, have the opportunity to advance to High-A Greenville before the end of the summer depending on how aggressive the Red Sox are willing to be.

Red Sox’ Craig Breslow on trade addition Carlos Narvaez: ‘He’s a guy that we’re really excited about’

The Red Sox did not pluck a player from the Yankees organization in the major- or minor-league phase of the Rule 5 Draft earlier this month, but they did swing a rare trade with their division rivals on the final day of the Winter Meetings in Dallas, Texas.

In exchange for pitching prospect Elmer Rodriguez and $250,000 in international bonus pool space, Boston acquired catcher Carlos Narvaez from New York on December 11. The move came just hours after the Red Sox included top catching prospect Kyle Teel in the five-player trade that netted them frontline starter Garrett Crochet from the White Sox.

Narvaez, who turned 26 late last month, comes to the Red Sox with just six games of major-league experience under his belt. The native Venezuelan originally signed with the Yankees for $50,000 as an international free agent coming out of Maracay in July 2015. He made his professional debut the following June and — in the process of working up the minor-league ladder — was added to New York’s 40-man roster for Rule 5 protection in November 2023.

Narvaez opened the 2024 season at Triple-A Scranton/Wilkes-Barre and was not called up for his big-league debut until mid-July. The right-handed hitter appeared in six games for the Yankees from July 20 through August 10, going 3-for-13 (.231) with three singles, two walks, and six strikeouts. From behind the plate, he threw out one of two possible base stealers before being optioned on August 13.

Narvaez would close out the year with Scranton/Wilkes-Barre, finishing with a .254/.370/.412 slash line with 20 doubles, 11 home runs, 58 RBIs, 54 runs scored, nine stolen bases, 56 walks, and 105 strikeouts in 96 games (403 plate appearances) for the RailRiders. Defensively, the 5-foot-11, 190-pound backstop gunned down 15 of 83 would-be base stealers. He also logged 114 innings at first base and three innings at third base.

Equipped with a strong arm and solid framing and receiving skills, Narvaez has spent his winter with the Cardenales de Lara of the Venezuelan Winter League (LVBP). Despite dealing with visa issues that resulted in him being away from the team for a bit, Narvaez still batted a stout .357/.456/.662 with five home runs and 18 RBIs in 23 regular-season games (90 plate appearances) for the Cardenales, who are now in the LVBP playoffs.

Having said that, it is worth noting that Venezuelan journalist Carlos V. Rodriguez reported on Monday that — regardless of how far the Cardenales advance in the playoffs — Narvaez will only play until January 7 because the Red Sox want him back in the United States to take part in team activities. That tracks with Narvaez being among the players expected to attend the first-ever Fenway Fest fan event in Boston on January 11.

Barring any other catching additions in the coming days or weeks, Narvaez will likely enter his first spring training with the Red Sox as the club’s top backup option behind Connor Wong. Chief baseball officer Craig Breslow acknowledged as much when speaking with reporters (including MassLive.com’s Chris Cotillo) via Zoom earlier Monday afternoon.

“He’s a guy that we’re really excited about,” Breslow said of Narvaez. “What we saw out of him in winter ball I think only enhances or reinforces that we think he’s a great complement to Connor. That doesn’t mean that we’ll stop looking but I think we brought Narvy in because of what he brings offensively but also more specifically in terms of pitch framing and receiving. We feel really good about that.”

Red Sox trade lefty reliever Cam Booser to White Sox for pitching prospect Yhoiker Fajardo

The Red Sox simultaneously created a 40-man roster spot and added a young pitching prospect to the organizational pipeline by connecting on their second trade in as many weeks with the White Sox on Saturday evening.

In exchange for left-handed reliever Cam Booser, who forged a 3.38 ERA in 43 relief appearances (42 2/3 innings) as a 32-year-old rookie this past season, Boston acquired right-hander Yhoiker Fajardo from Chicago.

Fajardo, 18, made his professional debut in the Dominican Summer League this year after signing with the White Sox for $400,000 as an international free agent coming out of Venezuela in February. The Villa de Cura native earned DSL Mid-Season All-Star honors en route to posting a 3.91 ERA (2.50 FIP) with 64 strikeouts to eight walks in 13 starts (50 2/3 innings) for Chicago’s rookie-level affiliate. Opposing hitters batted .260 against him.

Among the 19 Dominican Summer League pitchers who eclipsed the 50-inning mark in 2024, Fajardo ranked first in FIP and xFIP (2.33), third in strikeouts per nine innings (11.37), strikeout rate (30.2 percent), and swinging-strike rate (43.4 percent), and fourth in walks per nine innings (1.42), walk rate (3.8 percent), and groundball rate (55.6 percent), per FanGraphs. He also produced the highest BABIP (.365) of that group, which suggests that luck may not have necessarily been on his side.

Listed at 6-foot-3 and 181-185 pounds, Fajardo has been described by Baseball America’s Ben Badler as “a good athlete with an easy delivery that he repeats well from a consistent release point on all of his pitches.” The projectable righty still has plenty of room to grow physically but currently sits between 90-95 mph with his fastball while mixing in a low-80s slider and an occasional hard changeup.

Barring a surprise, Fajardo — who does not turn 19 until next October — will likely open the 2025 season in the Florida Complex League.

Top Red Sox prospect Marcelo Mayer provides update on lower back injury that cut his 2024 season short

After missing the final two months of the 2024 season with a lumbar strain in his lower back, top Red Sox prospect Marcelo Mayer provided an update on his health in a recent conversation with MassLive.com’s Sean McAdam.

“I’m really good,” Mayer told McAdam. “Lower back’s great. I’ve been cleared for a while now, so I’ve been progressing swinging-wise, doing my stuff and working hard in the weight room, doing whatever I can to get my body in the best position for this upcoming season.”

As noted by McAdam, Mayer has not done much in terms of hitting so far this winter, though that will likely change soon.

“I’m still ramping up,” Mayer said. “But as far as that goes, my swing feels phenomenal right now. It feels like I haven’t missed a beat, which is weird because usually when I take a week off, I feel extremely rusty. But I took like two months off and I feel great right now. I’ll be ready to (be a full-go for the start of spring training).”

Mayer, the No. 10 prospect in Baseball America’s top 100 rankings, saw his season cut short by injury for a second straight year over the summer. The recently-turned 22-year-old was limited to 78 games between High-A Greenville and Double-A Portland in 2023 due to a lingering left shoulder impingement that ultimately shut him down that August.

Mayer broke camp with Portland this past spring and was putting together a stellar season at the plate through late July. The left-handed hitter netted 2024 Eastern League Post-Season All-Star honors by batting .307/.370/.480 with 28 doubles, eight home runs, 38 RBIs, 60 runs scored, 13 stolen bases, 30 walks, and 66 strikeouts in 77 games (335 plate appearances) for the Sea Dogs.

On the other side of the ball, Mayer drew encouraging reviews for his defensive ability at shortstop, where he started 65 games and committed 10 errors in 212 chances with Portland this year. The 6-foot-3, 188-pound infielder also made exactly one start at third base for the second season in a row.

In the weeks following his second straight trip to the All-Star Futures Game, Mayer hit a snag. He was placed on Portland’s injured list on August 1, two days after leaving a game early with what was initially described as lower back and upper glute muscle soreness. Since the issue was deemed minor, the Red Sox proceeded to activate and then promote Mayer to Triple-A Worcester on August 12 with the expectation that he would quickly find his way into the lineup.

The soreness in Mayer’s back, however, persisted. Further medical evaluation, including an MRI, led to the diagnosis of a lumbar strain. Rather than act aggressively, the Red Sox ended Mayer’s season before he could even notch his first Triple-A at-bat by placing him on Worcester’s injured list on August 20 and sending him to extended spring training in Fort Myers, Fla. so he could focus on his rehab.

“Extremely frustrating. As a player, of course you don’t want to get injured,” said Mayer. “I work extremely hard while I play to try to prevent injury. I think I’ve just been unlucky these past couple of years. I don’t think it’s something that happened because I didn’t do that or didn’t do this. I fell (resulting in the shoulder injury), something I can’t control. And the other one, I just had a little back problem.

“It’s obviously not ideal, but that’s the situation I’ve been put in and all I can do now is work my ass off (to rehab),” he continued. “I went down to Florida (in the fall) for a month, worked with the trainers there, did workouts, did some core stuff. They sent me home and I continued that training, and I’m pretty much a full-go right now. I’ll start hitting around the new year, which is more than enough time for me. You don’t need to be hitting all off-season.”

Originally selected by Boston with the fourth overall pick in the 2021 draft out of Eastlake High School (Chula Vista, Calif.), Mayer — barring a trade or other surprise move — is expected to open the 2025 campaign at Worcester. If he can stay on the field and quell any concerns about his durability, he should be able to put himself in a position to make his major league debut before the season draws to a close.

Red Sox sign former All-Star, Rookie of the Year Michael Fulmer to two-year minor-league deal

The Red Sox signed free agent reliever Michael Fulmer to a minor-league contract last week, per the club’s MLB.com transactions log. According to MassLive.com’s Chris Cotillo, it is a two-year deal that will cover the 2024 and 2025 seasons.

As noted by Cotillo, the contract includes a $1.5 million major-league salary in both years. If Fulmer is selected to the 40-man roster in 2024 or 2025, his salary will be $1.5 million. The right-hander will also have the chance to earn an additional $2 million in incentives next year.

Fulmer, who turns 31 next month, is expected to miss the entirety of the 2024 season after undergoing UCL revision surgery on his right elbow last October. This comes after he previously underwent Tommy John surgery to repair that same ligament in March 2019.

Last year with the Cubs, where he worked with Red Sox chief baseball officer Craig Breslow, Fulmer posted a 4.42 ERA and 4.15 FIP with 65 strikeouts to 28 walks over 58 appearances (one start) spanning 57 innings of work in which he held opposing hitters to a .235 batting average against. He ranked in the 95th percentile of all big-league pitchers in hard-hit rate (30.3 percent) and the 92nd percentile in both average exit velocity (86.4 mph) and whiff rate (33.5 percent), per Baseball Savant.

A former first-round draft selection of the Mets out of Deer Creek High School (Edmond, Okla.) in 2011, Fulmer first broke in with the Tigers in 2016 after being part of the same trade that sent former Red Sox outfielder Yoenis Cespedes to New York the previous summer. The Oklahoma native got his major-league career with Detroit off to a promising start, as he took home American League Rookie of the Year honors as well as a 10th-place finish in Cy Young voting in 2016 before being named a first-time All-Star in 2017.

From that point forward, though, Fulmer has been hindered by injuries on numerous occasions. After his 2019 was wiped out because of Tommy John, the righty struggled to a 8.78 ERA in 10 starts during the COVID-shortened 2020 campaign. He then moved to Detroit’s bullpen in 2021 and has primarily worked as a reliever for the Tigers, Twins, and Cubs since then.

Altogether, Fulmer owns a lifetime 3.94 ERA in 262 career big-league outings (94 starts). When operating in a relief role, the 6-foot-3, 224-pound hurler has pitched to a 3.43 ERA with 190 strikeouts to 70 walks across 175 2/3 total innings. He also converted 19 of a possible 30 save opportunities in that stretch.

Before going under the knife while with the Cubs last fall, Fulmer averaged 83.2 mph with his sweeper, 94.2 mph with his four-seam fastball, 89.6 mph with his cutter, 94.8 mph with his sinker, and 89.9 mph with his changeup. He has past experience throwing a curveball as well.

Fulmer will presumably spend most, if not all of the 2024 campaign rehabbing in Fort Myers. Barring a surprise, he should be at Boston’s spring training camp as a non-roster invitee around this time next year.

The Red Sox, for their part, are no strangers when it comes to rehabbing injured free agent pitchers. Most recently, right-hander Wyatt Mills was brought back on a similar two-year minors pact earlier in the offseason after undergoing Tommy John surgery last July.

Like Fulmer, Mills is unlikely to pitch in 2024, though there is always a possibility something could change later in the year. In the meantime, neither Fulmer nor Mills will count against the Sox’ 40-man roster.
