Red Sox pitching prospect Wikelman Gonzalez caps off impressive month of June with another strong start for High-A Greenville

Red Sox pitching prospect Wikelman Gonzalez put the finishing touches on an impressive month of June on Friday night.

Gonzalez made his 14th start of the season for High-A Greenville in its 8-0 win over the Asheville Tourists at McCormick Field. The young right-hander tossed 5 2/3 scoreless innings, allowing just one hit and three walks to go along with 10 strikeouts to mark his second straight double-digit strikeout game and third of the year overall.

After retiring the first five batters he faced, Gonzalez issued a two-out walk in the bottom of the second. He then worked his way around a leadoff double in the third before stranding another base runner in the fourth and facing the minimum in the fifth. In the sixth, he recorded two quick outs before issuing a two-out walk to the last Tourist hitter he faced in Ryan Clifford. Gonzalez was then relieved by Casey Cobb, who ended the inning on four pitches.

Gonzalez himself finished with 90 pitches (58 strikes), inducing 17 swings-and-misses in the process of picking up his sixth winning decision of the season. In five June starts, the 21-year-old hurler went 4-0 with a 2.42 ERA and 2.38 FIP to go along with 43 strikeouts to 12 walks over 26 innings of work.

On the 2023 campaign as a whole, Gonzalez has pitched to a 4.50 ERA (3.41 FIP) with a South Atlantic League-leading 97 strikeouts to 40 walks in 58 innings for Greenville. Coming into play on Saturday, Gonzalez ranked first among qualified Sally League pitchers in strikeouts per nine innings (15.05) and strikeout rate (38 percent). He also ranked third in batting average against (.192), fifth in swinging-strike rate (16 percent), fifth in FIP, and sixth in xFIP (3.67), per FanGraphs.

A native of Venezuela, Gonzalez is in the midst of his fourth professional season after originally signing with the Red Sox for $250,000 as an international free agent coming out of Maracay in July 2018. The 6-foot, 167-pound righty throws from a three-quarters arm slot and operates with a four-pitch mix that consists of an upper-90s fastball, an upper-80s changeup, an upper-70s curveball, and an upper-80s slider. He is currently regarded by Baseball America as the No. 12 prospect in Boston’s farm system, which ranks fourth among pitchers in the organization.

Gonzalez, who does not turn 23 until next March, can become eligible for the Rule 5 Draft this winter if he is not added to the Red Sox’ 40-man roster by the deadline to do so in November. Assuming that he is not traded away within the next month, Gonzalez could be a candidate to make the jump from Greenville to Double-A Portland on the other side of the All-Star break — if not sooner.

Promoting Gonzalez would allow the Red Sox to evaluate how he fares against more advanced competition at the Double-A level. It would also give Gonzalez the opportunity to show other teams what he is capable of if he is made available later this month or down the road in December.

Red Sox relief prospect Luis Guerrero selected to participate in All-Star Futures Game

Red Sox pitching prospect Luis Guerrero has been selected to participate in next weekend’s All-Star Futures Game in Seattle, Major League Baseball announced on Friday.

Guerrero, one of the top young relievers in Boston’s farm system, will replace fellow Red Sox pitching prospect Shane Drohan, who left his start for Triple-A Worcester this past Sunday with a calf cramp. Drohan was pushed back for precautionary reasons but is expected to pitch next week, according to SoxProspects.com’s Chris Hatfield.

Guerrero, 22, will join infielders Marcelo Mayer and Nick Yorke in representing the Red Sox and suiting up for the American League at T-Mobile Park on July 8. The hard-throwing right-hander is currently regarded by Baseball America as Boston’s No. 30 prospect, which ranks 10th among pitchers in the organization.

In 26 appearances for Double-A Portland this season, Guerrero has posted a 1.19 ERA and 3.82 FIP with 27 strikeouts to 18 walks over 30 1/3 innings of work. He has put up those numbers while recording 13 saves in 15 opportunities and holding opposing hitters to a miniscule .147 batting average against.

A native of the Dominican Republic, Guerrero underwent surgery on his right knee as an infant and now walks with a limp as a result. He told The Boston Globe’s Alex Speier earlier this spring that he has limited mobility in his knee since the muscles in that area did not grow like the others.

“[But] for pitching, you just need to bend [the back knee] a little bit,” Guerrero explained. “My knee bends just as much as I need it to.”

Guerrero moved to the Boston-area as a child and then to Miami, Fla. for his senior year of high school. He was selected by the Red Sox in the 17th round of the 2021 amateur draft out of Chipola College and signed with the club for $122,500.

After not making his professional debut until last June, Guerrero made his way to High-A Greenville before the 2022 season came to a close. He was expected to return to Greenville for the start of the 2023 campaign, but he showed increased fastball velocity and wound up breaking camp with Portland as a result.

Prior to leaving Fort Myers, though, Guerrero appeared in five Grapefruit League spring training games as a minor-league call-up and left an impression on Red Sox manager Alex Cora.

“It’s impressive what he can do on a mound. Impressive,” Cora said of Guerrero when speaking with reporters (including MassLive.com’s Christopher Smith) ahead of Friday’s series opener against the Blue Jays in Toronto. “He has his limitations and for him to throw 100 (mph) with that split (is impressive). I saw him in spring training walking around one day after a workout. And I didn’t know the whole story. I saw him walking and I was like, ‘Are you OK?’ And then he told me what happened.

“I felt so bad because I didn’t know,” Cora added. “But then it’s like a lot of respect for him because he was the first one in the gym when we were there and he didn’t have to. He was always available when we brought him in as a backup pitcher.”

As Cora alluded to, Guerrero regularly throws in the upper-90s and can reach triple digits with his fastball. The 6-foot, 215-pound righty also features a mid-80s, whiff-inducing splitter as well as an 88-91 mph slider.

“I have a lot of respect for him,” said Cora. “For him to have the stuff that he has, you have to have not only the ability but you’ve got to have the heart and the courage to overcome what he has overcome and be a guy in that platform.”

Guerrero, who turns 23 in August, will presumably be a candidate to make the jump from Portland to Worcester on the other side of the All-Star break.

Red Sox outfield prospect Corey Rosier returns to Double-A Portland after getting first taste of Triple-A action

Red Sox outfield prospect Corey Rosier got his first taste of baseball at the Triple-A level last week.

In need of outfield depth at Triple-A Worcester, the Red Sox promoted Rosier from Double-A Portland on Thursday. The speedy 23-year-old was well aware that his first stint with the WooSox was going to be short-lived, telling reporters (including Tommy Cassell of The Telegram & Gazette) at Polar Park that he was just looking “to take the opportunity and run with it.”

Rosier made his WooSox debut later that night, coming on as a defensive replacement for starting outfielder Wilyer Abreu in the eighth inning. He popped out in his lone plate appearance. On Friday, Rosier made his first start, going 1-for-3 with a walk, a run scored, and two strikeouts out of the nine-hole. He also threw out a runner at second base in the fifth inning to make up for an earlier fielding error.

After sitting on Saturday, Rosier made one more start in right field for Sunday’s series finale against the Lehigh Valley IronPigs. Batting out of the nine-hole yet again, the left-handed hitter went 0-for-2 with a walk, a run scored, and a strikeout. He was also hit by a pitch in the fifth inning, which preceded a two-run home run off the bat of Nick Sogard.

All told, Rosier went 1-for-6 (.167) with a single, two runs scored, two walks, and three strikeouts in his first three games with the WooSox. He reached base in four of his nine trips to the plate. Defensively, the 5-foot-10, 180-pounder recorded one outfield assist and one fielding error while logging 20 innings between left and right field.

On the heels of his first go-around in Worcester, Rosier was added back to Portland’s roster on Wednesday, effectively switching places with the recently-promoted Ceddanne Rafaela. With the Sea Dogs this season, Rosier has batted a stout .307/.354/.452 (117 wRC+) to go along with 12 doubles, three triples, two home runs, 18 RBIs, 29 runs scored, 26 stolen bases, 13 walks, and 43 strikeouts across 182 plate appearances. He has also registered four outfield assists in 408 1/3 cumulative innings between the two corner spots.

Rosier, who turns 24 in September, is in his first full season as a member of the Red Sox organization. The Maryland native was acquired from the Padres alongside fellow prospect Max Ferguson and veteran first baseman Eric Hosmer in the trade that sent pitching prospect Jay Groome to San Diego last August.

A former 12th-round draft selection of the Mariners out of UNC Greensboro in 2021, Rosier is well-regarded for his speed. FanGraphs’ Eric Longenhagen went as far to rate Rosier’s speed tool as an 80 on the 20-80 scouting scale in his latest Red Sox prospects rankings.

“Rosier has several catalytic qualities: he’s an 80 runner with a good idea of the strike zone and he’s difficult to make miss within it,” Longenhagen wrote earlier this month. “Though he’ll occasionally ambush a middle-in pitch, Rosier mostly rips grounders to the right side and then hauls ass to first base. Despite his speed, he’s a poor outfield defender who makes a lot of routine plays look difficult and adventurous.”

Longenhagen also noted that he “loves the edge” Rosier (his No. 38 Boston prospect) plays with and “thinks his speed and contact ability will make him rosterable, but he basically has no position, which is going to severely limit his role.”

Outside of Longenhagen’s list for FanGraphs, Rosier is not currently regarded by any other notable publication (Baseball America, MLB Pipeline, SoxProspects.com) as one of the top 40 or so prospects in Boston’s farm system. That likely has to do with how much he relies on his speed in all aspects of his game.

Still, Rosier is undoubtedly an intriguing prospect who has been recognized by the Red Sox’ player development staff for his efforts so far in 2023. That much was made evident by him getting the opportunity to make a brief cameo with the WooSox, though that probably won’t be the last we see of him in Worcester this year.

Red Sox to promote top prospect Ceddanne Rafaela to Triple-A Worcester

The Red Sox are promoting top prospect Ceddanne Rafaela from Double-A Portland to Triple-A Worcester, as was first reported by The Boston Globe’s Alex Speier.

Rafaela was informed of the decision following Portland’s 7-3 loss to the Reading Fightin Phils at Hadlock Field on Sunday afternoon. He did not play in the game.

“It’s very exciting,” Rafaela told Speier. “I’ve been waiting for this chance. I’m happy I get it. I need to go up there and do the same thing I’ve been doing . . . I’ve been working, developing, and I feel very ready right now.”

In 60 games for the Sea Dogs this season, Rafaela batted .294/.332/.441 (107 wRC+) with 18 doubles, six home runs, 37 RBIs, 40 runs scored, an Eastern League-leading 30 stolen bases, 14 walks, and 55 strikeouts across 266 plate appearances. The right-handed hitting 22-year-old initially got his 2023 campaign off to a slow start, but he has turned it around as of late and is slashing a stout .341/.384/.533 (143 wRC+) in his last 34 games (152 plate appearances) dating back to May 13.

On the other side of the ball, Rafaela is considered to be one of the more polished defenders in the Red Sox organization, as evidenced by him being named the club’s Minor League Defensive Player of the Year in 2021 and 2022. This season alone, the versatile 5-foot-9, 165-pounder made 43 starts at center field and seven at shortstop for Portland. He committed eight errors in 163 defensive chances.

While the defensive abilities are undoubtedly there, there are some concerns when it comes to Rafaela’s plate discipline. He struck out in 20.7 percent and walked in only 5.3 percent of his plate appearances with the Sea Dogs this year, though he has worked to improve both of those marks in recent weeks.

A native of Curacao, Rafaela originally signed with the Red Sox for just $10,000 as an international free agent in June 2018. He has since risen through the ranks and was added to Boston’s 40-man roster last November in order to receive protection from the Rule 5 Draft.

Rafaela, who turns 23 in September, is currently regarded by Baseball America as the No. 5 prospect in the Red Sox farm system behind only Marcelo Mayer, Miguel Bleis, Nick Yorke, and Roman Anthony. He is now slated to join a talented WooSox roster that includes other top prospects such as Shane Drohan, Brandon Walter, Enmanuel Valdez, and Wilyer Abreu.

By earning a promotion to Worcester, Rafaela is one step closer to reaching the major-leagues. To get there, he will need to show that he can handle and succeed against advanced competition at the Triple-A level.

Red Sox to promote pitching prospects Isaac Coffey, Hunter Dobbins to Double-A Portland

The Red Sox are promoting pitching prospects Isaac Coffey and Hunter Dobbins from High-A Greenville to Double-A Portland, according to MassLive.com’s Christopher Smith.

Coffey, who turns 23 on Wednesday, has posted a 2.83 ERA and 3.92 FIP with a South Atlantic League-leading 83 strikeouts to just 10 walks in 11 starts (60 1/3 innings) for the Drive this season. The right-hander fanned eight over 5 2/3 frames in his last time out against the Greensboro Grasshoppers at Fluor Field this past Thursday.

Among qualified pitchers in the South Atlantic League, Coffey ranks third in strikeouts per nine innings (12.38), second in strikeout rate (34.4 percent), second in walks per nine innings (1.49), second in walk rate (4.1 percent), 10th in batting average against (.222), third in WHIP (1.01), seventh in swinging-strike rate (14.8 percent), 10th in ERA, 13th in FIP, and first in xFIP (2.78), per FanGraphs.

Coffey was selected by the Red Sox in the 10th round of last year’s draft out of Oral Roberts. The California native signed with the club for a mere $7,500 yet is currently regarded by SoxProspects.com as the No. 51 prospect in Boston’s farm system, which ranks 22nd among pitchers in the organization.

Standing at 6-foot-1 and 205 pounds, Coffey throws from a sidearm slot and operates with a four-pitch mix that consists of an 88-90 mph fastball that tops out at 91 mph, a 77-79 mph slider that features 10-to-4 break, and an 83-84 mph changeup that is considered to be a work in progress. He becomes the second member of the Sox’ 2022 draft class to make the jump from Greenville to Portland this season, joining fourth-rounder Chase Meidroth.

Dobbins, meanwhile, has forged a 2.63 ERA and 2.52 FIP with 44 strikeouts to just five walks in seven starts (41 innings) for the Drive this season. The 23-year-old righty also struck out eight across six two-run frames in his last time out against Greensboro this past Friday.

Among the 57 South Atlantic League pitchers who have accrued at least 40 innings to this point in the 2023 campaign, Dobbins ranks first in walks per nine innings (1.10) and walk rate (3.1 percent). He also ranks 20th in strikeout rate (27.3 percent), fourth in WHIP (0.95), and sixth in swinging-strike rate (16.8 percent) after not making his first start of the year until May 7.

Dobbins was selected by the Red Sox in the eighth round of the 2021 amateur draft out of Texas Teach. After undergoing Tommy John surgery earlier that spring, the Lone Star State native signed with Boston for $197,500 and did not make his professional debut until last July. He currently is not rated by SoxProspects.com as one of the top pitching prospects in the system.

Listed at 6-foot-2 and 185 pounds, Dobbins — who turns 24 in August — throws from a high-three-quarters arm slot and works with a four-pitch mix that consists of a 91-94 mph fastball that tops out at 96 mph, a 74-78 mph curveball, an 83-85 mph circle changeup, and a high-80s slider that is rarely used.

Both Coffey and Dobbins figure to join a starting rotation mix in Portland that includes C.J. Liu, Brian Van Belle, Sterling Sharp (who is currently on the injured list), Grant Gambrell, and Wyatt Olds. The Sea Dogs open a six-game series against the Reading Fightin Phils at Hadlock Field on Tuesday night.

Red Sox promote catching prospect Stephen Scott to Triple-A Worcester

The Red Sox have promoted catching prospect Stephen Scott from Double-A Portland to Triple-A Worcester, per the club’s minor-league transactions log.

Scott, 26, is currently regarded by SoxProspects.com as the No. 35 prospect in Boston’s farm system. The left-handed hitter batted .248/.369/.448 (124 wRC+) with five doubles, one triple, six home runs, 22 RBIs, 23 runs scored, four stolen bases, 24 walks, and 34 strikeouts in 37 games (149 plate appearances) with the Sea Dogs this season.

Among qualified Eastern League hitters coming into play on Friday, Scott ranks 22nd in on-base percentage, 24th in slugging percentage, 24th in OPS (.817), 20th in isolated power (.200), 23rd in wRC+, and 15th in walk rate (16.1 percent), according to FanGraphs.

Defensively, Scott logged 257 innings at catcher for Portland while splitting time behind the plate with Nathan Hickey and Elih Marrero. In those 257 innings, the 5-foot-11, 205-pound backstop allowed six passed balls and threw out 61 would-be base stealers.

A native of North Carolina, Scott was originally selected by the Red Sox in the 10th round of the 2019 amateur draft out of Vanderbilt. At the time he signed with Boston for just $50,000 that July, Scott was primarily viewed as a first baseman/corner outfielder, but he began catching full-time last year and has not really looked back since.

In Worcester, Scott will join Caleb Hamilton and Ronaldo Hernandez in helping fill the void left behind by veteran catcher Jorge Alfaro, who exercised the opt-out in his minor-league contract with Boston last week and was granted his release from the organization this past Saturday.

Red Sox prospect Ceddanne Rafaela tallies 3 hits, steals 3 bases in latest strong showing for Double-A Portland

Versatile Red Sox prospect Ceddanne Rafaela recorded his fourth three-hit game of the season in Double-A Portland’s 6-2 win over the Akron RubberDucks on Tuesday night.

Leading off and starting in center field for the Sea Dogs to kick off a six-game series at Hadlock Field, Rafaela went 3-for-4 with three singles and one run scored. The speedy 22-year-old extended his hitting streak to 11 games and also stole three bases.

Following Tuesday’s performance, Rafaela is now batting .284/.322/.411 with 12 doubles, four home runs, 31 RBIs, 32 runs scored, an Eastern League-leading 25 stolen bases (in 31 attempts), 11 walks, and 40 strikeouts in 46 games (205 plate appearances) with Portland so far this season.

Rafaela came into the year with high expectations after a breakout 2022 campaign that netted him a spot on the Red Sox’ 40-man roster last November. But the right-handed hitter got off to an underwhelming start to begin his first full season with the Sea Dogs.

After going 0-for-5 with two strikeouts in a 4-3 loss to the Hartford Yard Goats on May 18, Rafaela found himself slashing .262/.309/.346 through 31 games (139 plate appearances). He has since registered at least one hit in 14 of his last 15 games and is hitting .333 (20-for-60) over that stretch. Since the calendar flipped from May to June, he has gone 10-for-22 (.455) at the plate with two doubles, one homer, five runs driven in, five runs scored, five stolen bases, zero walks, and just one strikeout.

On the other side of the ball, Rafaela has split time between shortstop and center field this season. The 5-foot-9, 152-pounder has logged 66 innings at the former and 286 1/3 innings at the latter after making his 33rd start of the year there on Tuesday.

Originally signed for just $10,000 as an international free agent coming out of Curacao in July 2017, Rafaela has risen through the ranks and is currently regarded by Baseball America as the No. 3 prospect in Boston’s farm system and the No. 70 prospect in the sport.

Considering how well he has been performing as of late, one has to wonder if Rafaela could soon be on the verge of a promotion to Triple-A Worcester. The Willemstad native does not turn 23 until September, but he has played nearly a full season’s worth of games at the Double-A level after first making the jump from High-A Greenville last June.

With plus speed and solid instincts in the field, Rafaela has the ability to play two key defensive positions at a high level. The fact that he was named the Red Sox’ Defensive Player of the Year in each of the last two seasons reflects as much.

Though there is still room for improvement as far as pitch selection and plate discipline are concerned, it may be best for Rafaela to continue developing in Worcester so that he can face new challenges at a more advanced level moving forward.

Red Sox promote infield prospect Christian Koss to Triple-A Worcester

To accommodate the addition of shortstop Marcelo Mayer to Double-A Portland’s roster, the Red Sox have promoted fellow infield prospect Christian Koss to Triple-A Worcester, per the club’s minor-league transactions log.

Koss, 25, batted .224/.283/.336 with seven doubles, one triple, two home runs, 10 RBIs, 18 runs scored, 11 stolen bases, 10 walks, and 33 strikeouts in 38 games (147 plate appearances) for the Sea Dogs this season.

Considering how much better he did in Portland last year (.739 OPS in 125 games), those numbers may seem underwhelming on a broader scope. Still, Koss has been more productive at the plate as of late. Dating back to May 21, for instance, the right-handed hitter has gone 7-for-23 (.304) with two doubles, one homer, three RBIs, five runs scored, two stolen bases, zero walks, and seven strikeouts over his last seven games. That homer came as part of a two-hit effort in Sunday’s 10-8 loss to the New Hampshire Fisher Cats at Hadlock Field.

On the other side of the ball, Koss has seen the majority of his playing time this season come at shortstop, where he has committed just one error in 281 1/3 innings. The versatile 6-foot-1, 182-pounder has also made two starts at second base, one start at third base, and one start in left field.

“He loves to play the game,” Red Sox manager Alex Cora said of Koss back in March. “He’s made some great plays at shortstop, very athletic, versatile. He’s a good one.”

A former 12th-round draft selection of the Rockies coming out of UC Irvine in 2019, Koss was dealt to the Red Sox for left-hander Yoan Aybar in December 2020. The Riverside, Calif. native is currently regarded by SoxProspects.com as the No. 34 prospect in Boston’s farm system.

With the WooSox, Koss is slated to join a crowded infield mix that already includes Bobby Dalbec, Ryan Fitzgerald, Niko Goodrum, David Hamilton, and Nick Sogard. It is worth mentioning that he can once again become eligible for the Rule 5 Draft this winter if he is not added to the Sox’ 40-man roster by the protection deadline in November.

Red Sox promote relief prospect Theo Denlinger to Triple-A Worcester

As part of a slew of minor-league roster moves, the Red Sox promoted relief prospect Theo Denlinger from Double-A Portland to Triple-A Worcester on Tuesday.

Denlinger, 26, was acquired from the White Sox back in February in exchange for fellow right-hander Franklin German.

To begin his first season as a member of the Red Sox organization, Denlinger posted a 2.29 ERA and 3.10 FIP with 20 strikeouts to seven walks in 14 relief appearances (19 2/3 innings) for the Sea Dogs. Opponents only hit .149 against him while his 6.4 percent line-drive rate and 57.4 percent groundball rate would rank among the best in the Eastern League if he was qualified.

Denlinger, who turns 27 in July, is currently regarded by SoxProspects.com as the No. 48 prospect in Boston’s farm system, which ranks 19th among pitchers in the organization. The Iowa native was originally selected by Chicago in the seventh round of the 2021 amateur draft out of Bradley College (Peoria, Ill.) and signed with the club for just $10,000.

Standing at a burly 6-foot-3 and 240 pounds, Denlinger primarily operates with a two-pitch mix that consists of a 93-96 mph fastball that tops out at 97 mph and a 79-82 mph slider that features long, 11-to-5 break. He has also shown the ability to throw a two-seam fastball and cutter, both of which he first implemented last year.

Denlinger becomes the second member of the White Sox’ 2021 draft class to make the jump to Worcester this season, joining fellow righty reliever Taylor Broadway. Broadway, of course, was acquired from Chicago as the player to be named later in last August’s Reese McGuire/Jake Diekman trade. He currently owns a 5.40 ERA (6.91 FIP) in 15 outings (23 1/3 innings) for the WooSox.

Troye, Bell also promoted

Denlinger was not the only Red Sox relief prospect to receive a promotion on Tuesday. Righties Christopher Troye and Brock Bell were also moved up to Portland and Greenville, respectively.

Troye, 24, forged a 1.96 ERA and 3.60 FIP with 37 strikeouts to nine walks in 14 appearances (18 1/3 innings) for Greenville. The 2021 12th-round draft pick out of UC Santa Barbara has struck out nearly 49 percent of the batters he has faced so far this season.

Bell, 25, produced a 4.58 ERA and 4.64 FIP with 15 strikeouts to five walks in 11 appearances (19 2/3 innings) for Low-A Salem. The 2019 seventh-round selection out of State College of Florida, Manatee–Sarasota is the son of former All-Star infielder Jay Bell.

Red Sox to promote top prospect Marcelo Mayer to Double-A Portland

The Red Sox are promoting top prospect Marcelo Mayer from High-A Greenville to Double-A Portland, according to The Boston Globe’s Alex Speier.

Mayer will join the Sea Dogs in New Jersey this week for their upcoming series against the Somerset Patriots, the Double-A affiliate of the Yankees. The 20-year-old shortstop would then be on track to make his Hadlock Field debut on June 6, when the Sea Dogs return home to host the Akron RubberDucks (Guardians affiliate) in the first of a six-game set.

The promotion comes at a time when Mayer has been absolutely raking with Greenville. In 18 games with the Drive this month, the left-handed hitter has slashed a stout .321/.357/.641 with seven doubles, six home runs, 23 RBIs, 14 runs scored, two stolen bases, four walks, and 17 strikeouts over 84 plate appearances.

On the 2023 campaign as a whole, Mayer has batted .290/.366/.524 with 11 doubles, one triple, seven homers, 34 runs driven in, 23 runs scored, five stolen bases, 17 walks, and 34 strikeouts in 35 games (164 plate appearances) for Greenville. He missed some time earlier this month due to some left shoulder soreness, but now appears to be fully healthy.

Among qualified hitters in the South Atlantic League, Mayer currently ranks 15th in batting average, 11th in slugging percentage and OPS (.890), seventh in extra-base hits (19), ninth in total bases (76), and 11th in isolated power (.234), per MiLB.com.

On the other side of the ball, Mayer has unsurprisingly seen all of his playing time on the field this season come at shortstop. The 6-foot-2, 188-pounder served as Greenville’s designated hitter on Sunday, but has otherwise logged 279 innings at short while committing a total of seven errors in 99 defensive opportunities.

A native of California, Mayer was originally selected by the Red Sox with the fourth overall pick in the 2021 amateur draft out of Eastlake High School. He became Boston’s highest-drafted player since 1967 and signed with the club for $6.664 million.

Less than two full years after signing, Mayer now finds himself one step closer to the major-leagues. As noted by Speier, he is the youngest Red Sox draftee to reach Double-A since 2010, when both Anthony Rizzo and Casey Kelly made the jump to Portland.

Mayer, who does not turn 21 until December, is currently regarded by Baseball America as the No. 1 prospect in Boston’s farm system and the No. 12 prospect in the sport. Barring a surprise, he will likely spend the rest of the season with the Sea Dogs, which could — in theory — put him on track to garner big-league consideration at some point in 2024.

For the time being, though, Mayer will join a talented Sea Dogs roster that includes No. 3 prospect Ceddanne Rafaela, No. 7 prospect Nick Yorke, No. 15 prospect Nathan Hickey, No. 18 prospect Matthew Lugo, No. 23 prospect Niko Kavadas, and No. 27 prospect Chase Meidroth.

Mayer, Meidroth, and Hickey were all on Greenville’s Opening Day roster.
