Red Sox promote pitching prospect acquired in offseason trade to Low-A Salem

The Red Sox have promoted rising pitching prospect Yhoiker Fajardo from the Florida Complex League to Low-A Salem, according to the club’s MiLB.com transactions log.

Fajardo was among the top arms in the Florida Complex League to begin the 2025 season. In six appearances (four starts) for the FCL Red Sox, the 18-year-old right-hander posted a 0.44 ERA and 2.71 FIP with 24 strikeouts to seven walks over 20 2/3 innings pitched. Opposing hitters batted just .134 against him.

Coming into play on Tuesday, Fajardo was one of 41 pitchers to have thrown at least 20 innings in the FCL so far this year. Among those 41, he ranked first in ERA, FIP, and line-drive rate (2.3 percent), second in batting average against and WHIP (0.77), sixth in strikeout rate (31.6 percent), seventh in xFIP (3.53), 10th in strikeouts per nine innings (10.45), 12th in groundball rate (51.2 percent), and 16th in walks per nine innings (3.05), per FanGraphs.

Fajardo was acquired by the Red Sox from the White Sox for left-handed reliever Cam Booser in December. The native Venezuelan originally signed with Chicago for $400,000 as an international free agent coming out of Villa de Cura last February. He enjoyed a strong professional debut in the Dominican Summer League that culminated in him being recognized as a 2024 DSL All-Star.

Upon switching organizations for the first time in his career over the winter, Fajardo entered the 2025 campaign ranked by both Baseball America and SoxProspects.com as the No. 40 prospect in Boston’s farm system. The projectable 6-foot-3, 181-pound righty throws from a three-quarters arm slot and currently operates with a three-pitch mix that consists of a mid-90s fastball (topped out at 97.4 mph with it last Friday), a low-80s slider, and a high-80s changeup, as noted in his SoxProspects.com scouting report.

It is unclear when Fajardo, who does not turn 19 until October, will make his full-season debut for Salem. Still, with another young arm in the Red Sox pitching pipeline set to move up a level and encounter a new challenge, this is nonetheless an exciting development.

Red Sox’ Austin Ehrlicher named Carolina League Pitcher of the Week

Red Sox pitching prospect Austin Ehrlicher has been named the Carolina League Pitcher of the Week for the week of June 9-15, Minor League Baseball announced on Monday.

Ehrlicher was nearly perfect in his latest start for Low-A Salem on Sunday afternoon. Going up against Delmarva on the road, the 22-year-old right-hander walked just one and struck out a season-high of seven over five scoreless, no-hit innings. He retired 15 of the 16 batters he faced, throwing 68 pitches (46 strikes) and generating 10 swings and misses.

Despite Ehrlicher’s strong showing on the mound, the Red Sox dropped Sunday’s series finale to the Shorebirds at Arthur W. Perdue Stadium by a final score of 5-4 to fall to 24-37 on the season.

Ehrlicher has forged a 3.86 ERA (3.03 FIP) with 35 strikeouts to 18 walks in 11 appearances (seven starts) spanning 28 innings for Salem so far this season. The righty began the year in the bullpen but struggled in that role, allowing six earned runs in 5 1/3 innings of relief through the end of April. He moved to the Red Sox’ rotation in early May and has since posted a 2.38 ERA (3.12 FIP) with 25 strikeouts to 13 walks over 22 2/3 innings as a starter while holding opposing hitters to a .192 batting average.

Among 96 pitchers in the Carolina League who have thrown at least 28 innings to this point in the season, Ehrlicher ranks ninth in FIP, 13th in strikeouts per nine innings (11.25), 15th in strikeout rate (29.2 percent), 40th in batting average against (.222) and xFIP (3.80), 44th in ERA, and 46th in swinging-strike rate (12.4 percent), per FanGraphs.

Ehrlicher, who turned 22 earlier this month, was originally selected by the Red Sox in the 18th round (549th overall) of the 2022 draft out of Santa Rosa Junior College. As a draft-and-follow pick, the California native did not sign with the Red Sox until June 2023, forgoing his commitment to transfer to Arizona State in the process of doing so. He received a $200,000 signing bonus but was working his way back from an elbow injury at that time, which pushed his professional debut back until last April. He then made two relief appearances for Salem before ultimately being shut down for the remainder of the 2024 season with right shoulder inflammation.

Now healthy, Ehrlicher is showing flashes of his intriguing potential. A former two-sport athlete who also played basketball at Santa Rosa, Ehrlicher stands at 6-foot-5 and 185 pounds. He throws from a three-quarters arm slot and primarily operates with a three-pitch mix that consists of a 92-94 mph fastball, an 83-86 mph sweeper, and an 89-90 mph changeup, as noted in his SoxProspects.com scouting report.

Ehrlicher is not currently ranked among Boston’s top 60 prospects by SoxProspects.com, which describes him as having “several key traits, including standout athleticism, projectability, and feel for spin.” He is the third Red Sox minor-leaguer to take home Carolina League Pitcher of the Week honors this season, joining fellow righties Blake Aita (a two-time winner) and Trennor O’Donnell.

Moving forward, it should be worthwhile to see if Ehrlicher can leverage his performance with Salem into a promotion to High-A Greenville in the not-so-distant future.

How has ex-Red Sox pitching prospect Elmer Rodriguez fared since being traded to Yankees?

In light of Carlos Narvaez’s late-game heroics against his former team at Fenway Park on Friday night, it feels like an appropriate time to check in on how the prospect the Red Sox dealt to the Yankees for their breakout catcher in what looked like a minor trade six months ago is faring in his new organization so far.

Funnily enough, that prospect, Elmer Rodriguez, worked out of the bullpen for the first time this season against High-A Greenville on Friday night. In five scoreless innings of relief for Hudson Valley (New York’s High-A affiliate), the 21-year-old right-hander scattered just two hits and two walks while striking out eight of the 18 batters he faced. He threw 76 pitches (44 strikes), generating 12 swings-and-misses as the Renegades blanked the Drive, 1-0.

Through his first 11 outings (10 starts) for Hudson Valley, Rodriguez has forged a 2.70 ERA and 2.47 FIP with 74 strikeouts to 25 walks over a staff-leading 60 innings of work in which opponents have batted just .172 against him. That includes a .205 batting average against right-handed hitters and a .133 batting average against left-handed hitters.

Among 20 qualified South Atlantic League hitters coming into play on Saturday, Rodriguez ranked second in batting average against, FIP, and groundball rate (52.9 percent), third in xFIP (3.10), fourth in strikeouts per nine innings (11.10), strikeout rate (30.3 percent), ERA, and WHIP (1.03), and fifth in swinging-strike rate (14.6 percent), per FanGraphs.

A Puerto Rican native, Rodriguez was originally selected by the Red Sox in the fourth round (105th overall) of the 2021 draft out of Leadership Christian Academy in Guaynabo. He received an under-slot $497,500 signing bonus and slowly worked his way up Boston’s organizational ladder before ending the 2024 season in Greenville. Along with $250,000 in international bonus pool space, he was traded to New York for Narvaez on the final day of the Winter Meetings in December.

Rodriguez entered the 2025 campaign regarded by Baseball America as the Yankees’ No. 16 overall prospect, but has since moved up to the No. 4 spot, which ranks third among pitchers in New York’s farm system behind only fellow righties Bryce Cunningham and Carlos Lagrange. As noted in his Baseball America scouting report, the 6-foot-3 hurler boasts a diverse pitch mix that includes an upper-90s fastball that reaches 98-99 mph, a gyro slider, a sweeper, a curveball, and a splitter.

Rodriguez, who turns 22 in August, could very well be in line for a promotion from Hudson Valley to Double-A Somerset shortly. That is noteworthy when considering the fact that he can become eligible for the Rule 5 Draft for the first time this winter if he is not added to New York’s 40-man roster by the November protection deadline.

Though there are still some things to iron out, such as his command and developing arsenal, a new challenge for Rodriguez in the form of a move from High-A to Double-A would surely aid Yankees decision makers in determining if he is worthy of a 40-man roster spot in the coming months.

Red Sox promote pitching prospect Blake Aita to High-A Greenville

The Red Sox are promoting pitching prospect Blake Aita from Low-A Salem to High-A Greenville, according to Chase Ford of MiLB Central.

Aita, who turns 22 on Wednesday, is currently regarded by SoxProspects.com as Boston’s No. 43 prospect, which ranks 23rd among pitchers in the organization. The right-hander posted a 4.24 ERA (3.52 FIP) with 45 strikeouts to nine walks in 10 outings (nine starts) spanning a staff-leading 51 innings for Salem to open his first full professional season. Opposing hitters batted .240 against him.

Among 14 qualified pitchers in the Carolina League entering the week, Aita ranked first in walks per nine innings (1.59) and walk rate (4.4 percent), second in WHIP (1.08) and xFIP (3.32), fourth in groundball rate (49.3 percent), fifth in FIP and line-drive rate (19.2 percent), sixth in strikeout rate (22 percent), and seventh in strikeouts per nine innings (7.94), per FanGraphs.

A two-time Carolina League Pitcher of the Week award recipient in his first stint with Salem, Aita was selected by the Red Sox in the sixth round (177th overall) of last summer’s draft out of Kennesaw State, where he earned 2024 All-Atlantic Sun First Team honors. As a draft-eligible sophomore, the Georgia native signed for an under-slot $300,000 in late July but did not make his professional debut until earlier this year.

Standing at 6-foot-4 and 215 pounds, Aita throws from a high-three-quarters arm slot and incorporates a medium-high leg kick into his delivery. The sturdy righty primarily operates with a 92-95 mph fastball (up from 89-92 mph in college), an 80-82 mph sweeper, an 86-89 mph cutter, and an 85-89 mph changeup, as noted in his SoxProspects.com scouting report.

“He’s been great so far,” Red Sox senior director of player development Brian Abraham said of Aita last month. “He worked hard all offseason and spring training to set himself up for success throughout the year. He added velo to his fastball along with his secondaries and continues to pound the zone. His sweeper has been a big weapon, used for strikes and chase against both sides. Very pleased with the consistency and constant improvement daily.”

With this promotion, Aita is now slated to join a talented pitching staff in Greenville that — as of this writing — includes fellow 2024 draftees Payton Tolle, John Holobetz, Brandon Clarke, and Matt McShane.

Red Sox’ David Sandlin named Eastern League Pitcher of the Week

Red Sox pitching prospect David Sandlin has been named the Eastern League Pitcher of the Week for the week of May 26-June 1, Minor League Baseball announced on Monday.

Sandlin threw a seven-inning complete-game shutout in Game 1 of Double-A Portland’s doubleheader on the road against the Altoona Curve at Peoples Natural Gas Field last Thursday. The 24-year-old right-hander scattered three hits and one walk while striking out eight over seven scoreless innings. He retired the final eight batters he faced and finished with 83 pitches (56 strikes), inducing eight swings and misses.

The Sea Dogs ultimately defeated the Curve, 3-0, in Game 1 of Thursday’s doubleheader and went on to sweep the twin bill with a 9-6 victory in the nightcap.

Through nine appearances (eight starts) for Portland to this point in the season, Sandlin has posted a 3.77 ERA (3.42 FIP) with 45 strikeouts to 12 walks over a staff-leading 43 innings of work. Opposing hitters have batted .239 against him.

Among 25 qualified pitchers in the Eastern League, Sandlin notably ranks sixth in walks per nine innings (2.51) and xFIP (3.47), seventh in walk rate (6.8 percent) and FIP, and ninth in strikeouts per nine innings (9.42), strikeout rate (25.6 percent), swinging-strike rate (12.2 percent), and WHIP (1.19), per FanGraphs.

Sandlin entered the 2025 campaign regarded by Baseball America as the No. 7 prospect in Boston’s farm system, ranking second among pitchers in the organization behind only fellow righty Luis Perales. The former 2022 11th-round draft pick out of Oklahoma was acquired by the Red Sox from the Royals for reliever John Schreiber last February. He split the 2024 season between High-A Greenville and Portland, compiling a 5.34 ERA (4.78 FIP) across 18 starts spanning 57 1/3 total innings.

Listed at a sturdy 6-foot-4 and 215 pounds, Sandlin has primarily featured a five-pitch mix this season. Throwing from a three-quarters arm slot, the athletic hurler regularly averages 94-97 mph with a fastball that has reached 99 mph in-game after touching triple digits last year and over the winter. He has also incorporated a 90-93 mph slider, an 85-88 mph sweeper, an 88-91 mph splitter, and a 77-91 mph curveball into his diverse arsenal.

Sandlin, who just turned 24 in February, can become eligible for the Rule 5 Draft for the first time in his professional career this winter if he is not added to Boston’s 40-man roster by the protection deadline in November. With that, it would not be surprising if the fireballer were to receive a promotion to Triple-A Worcester in the near future as the Red Sox continue to assess whether he is worthy of a 40-man roster spot.

Red Sox promote local pitching prospect Shea Sprague to High-A Greenville

The Red Sox have promoted pitching prospect Shea Sprague from Low-A Salem to High-A Greenville, according to the club’s MiLB.com transactions log.

Sprague, 22, was selected by the Red Sox in the 13th round (387th overall) of last summer’s draft as a junior coming out of North Carolina. The Hanover, Mass. native — who graduated from Boston College High School in 2021 and attended Elon University for the first two years of his collegiate career — signed with his hometown team for a slightly-over-slot $155,000 but did not make his professional debut until last month.

Sprague struggled out of the gate to begin the 2025 season, surrendering 12 runs (nine earned) in his first two outings (5 2/3 innings) for Salem. The left-hander seemingly flipped a switch on April 23, however, only allowing four earned runs over his next five appearances (24 2/3 innings) while holding opposing hitters to a .195 batting average leading up to Friday’s promotion.

“I think I just settled in, started going after guys,” Sprague said of his early-season turnaround in a recent conversation with MassLive.com’s Christopher Smith. “Kind of went through a similar preseason, early-season struggle last year at UNC, trying to be too cute. But I just started going at guys and trusting my stuff. So that’s probably been the biggest change. Nothing major.”

Overall, Sprague posted a 3.86 ERA (2.45 FIP) with 35 strikeouts to nine walks in seven outings (two starts) spanning 30 1/3 innings for Boston’s Carolina League affiliate. In a case of reverse splits, he proved to be more effective against right-handed hitters (.247 opponents’ batting average) than left-handed hitters (.304 opponents’ batting average), which happened to him in college as well.

Among the 45 pitchers in the Carolina League who had thrown at least 30 innings coming into play on Friday, Sprague ranked second in FIP, fourth in xFIP (3.01), fifth in swinging-strike rate (14.8 percent), eighth in walk rate (6.9 percent), ninth in walks per nine innings (2.67), 10th in strikeouts per nine innings (10.38), 12th in strikeout rate (26.7 percent), 20th in groundball rate (43.4 percent), and 21st in ERA, per FanGraphs.

Standing at 6-foot-3 and 215 pounds, Sprague throws from a three-quarters arm slot and operates with a four-pitch mix that consists of an 89-92 mph fastball with sink, a low-80s whiff-inducing changeup, a 79-81 mph gyro slider, and a developing sweeper. The projectable southpaw told Smith that one of his goals is to continue adding velocity to his heater and get in the 92-94 mph or 93-95 mph range within the next year.

“The Red Sox stress to us just the importance of velocity,” said Sprague, who is doing drills with weighted plyo balls as part of his side work. “Obviously, I think a lot of velocity comes from physical development, so just getting bigger, stronger, faster. And just throwing more intent more often. Workload and all that stuff. So they have it down to a science, and they’re good about it. It just comes with time, keep working hard, and keep throwing hard.”

Sprague, who just turned 22 in January, is not currently ranked among Boston’s top pitching prospects by publications such as Baseball America, MLB Pipeline, or SoxProspects.com. He is, however, slated to join a pitching staff in Greenville that includes the likes of fellow southpaws Payton Tolle, Eduardo Rivera, Noah Dean, Brandon Clarke, Michael Sansone, and Zach Fogell.

Red Sox sign former Athletics, Braves farmhand Jorge Juan to minor-league deal

The Red Sox signed free-agent reliever Jorge Juan to a minor-league contract on Tuesday. He was assigned to Double-A Portland but was subsequently placed on the Sea Dogs’ suspended list due to a “prior three-game suspension he had to serve from his previous organization for on-field actions,” according to a team source.

Juan, 26, was released by the Braves earlier this month after spending the last season-plus in the organization. The right-hander posted a 5.11 ERA (4.50 FIP) with 53 strikeouts to 28 walks over 34 relief (37 innings) at Double-A in 2024, then logged a 7.50 ERA (6.27 FIP) with 11 strikeouts to six walks in seven appearances (six innings) between Low-A and Double-A to begin this year.

Juan threw behind a batter and was ejected from his final game with Atlanta’s Double-A affiliate, the Columbus Clingstones, on May 10. He was then cut loose by the Braves on May 11, but not before apparently being handed down a three-game suspension that did not go into effect until he signed with the Red Sox this week. As such, it does not appear as though he can make his organizational debut for Portland until Friday at the earliest.

Juan is now in line to pitch for the third organization of his professional career. The righty originally signed with the then-Oakland Athletics as an international free agent coming out of the Dominican Republic in July 2017. He was added to Oakland’s 40-man roster for Rule 5 protection purposes in November 2021, only to be designated for assignment and released the following May. He was re-signed to a minor-league deal but never advanced past the Double-A level before leaving the A’s for the Braves as a minor-league free agent at the conclusion of the 2023 campaign.

Altogether, Juan owns a lifetime 4.74 ERA (4.68 FIP) in 120 career minor-league appearances (22 starts) spanning 216 1/3 innings dating back to June 2018. That includes a 5.61 ERA with 99 strikeouts to 68 walks over 66 total relief outings (77 innings) at the Double-A level, where opposing hitters have batted .223 against him.

Listed at an imposing 6-foot-8 and (likely heavier than) 200 pounds, Juan has struggled with injuries and his command in the past, but has proven to be effective when healthy and locating his pitches. His arsenal has primarily consisted of a mid-90s fastball that touches 99 mph, a mid-80s power breaking ball, and a 90 mph changeup. FanGraphs’ Eric Longenhagen ranked Juan as the Braves’ No. 37 prospect earlier this spring, writing the following:

“Juan is enormous, but he’s a short-strider who generates much less extension than you’d expect from a pitcher this big. He tends to be relatively upright at release, which gives his pitches the steep plane of a runaway truck ramp. This most benefits Juan’s power breaking ball, which doesn’t pop out of his hand in an identifiable way. Juan’s size, arm strength, and breaking ball performance give him a shot to break into a big league bullpen as a late-bloomer.”

Juan, who does not turn 27 until next March, becomes the latest in a long line of behemoths the Red Sox have added to their pitching pipeline under chief officer Craig Breslow. It should be worthwhile to see how they handle his development moving forward.

Red Sox purchase contract of 6-foot-7 lefty PJ Labriola from Frontier League team

The Red Sox officially purchased the contract of left-hander PJ Labriola from the New York Boulders of the independent Frontier League on Wednesday, per the club’s MLB.com transactions log.

Labriola opened the 2025 season in New York after signing with the club in early March. The 24-year-old appeared in three games for the Boulders this month, allowing five runs (four earned) on seven hits, one walk, and two strikeouts over three innings. He recorded the first save of his professional career against the Rox in Brockton, Mass., last Friday.

“As soon as we started to pursue PJ this winter, we knew that he was a special player, and we also knew that he was very much of the radar of a few different organizations,” Boulders manager TJ Stanton said in a statement released by the team on Monday. “I could not be happier for PJ and absolutely love getting the opportunity to be a part of these great players’ baseball journeys. Hopefully there will be many more to come!”

A native of Sarasota, Fla., Labriola spent the first three years of his collegiate career at Clemson before transferring to North Carolina State in 2023. The lefty compiled an 8.58 ERA in 22 appearances (28 1/3 innings) over two seasons with the Wolfpack and went undrafted as a fifth-year senior last summer. He then spent the remainder of 2024 pitching for the Frederick Keys of the MLB Draft League and the Rocky Mountain Vibes of the independent Pioneer League, forging a 6.00 ERA across 12 outings (12 innings) between the two clubs.

Listed at 6-foot-7 and 223 pounds, Labriola was among the standout performers at Tread Athletics’ series of pro days back in January. As part of that showcase in Pineville, N.C., the towering southpaw featured a mid-90s fastball, an 89-90 mph cutter, and an 86-plus mph gyro slider. He likely caught the Red Sox’ attention at that time and, following a brief stint in the Frontier League, it ultimately culminated in an agreement between the two sides.

Labriola, who does not turn 25 until November, has been assigned to the Florida Complex League Red Sox for the start of his organizational tenure. With that being said, it would not be surprising if he were to join one of Boston’s lower-level full-season affiliates (either Low-A Salem or High-A Greenville) as an additional bullpen option before long.

Red Sox promote relief prospect Michael Sansone to High-A Greenville

The Red Sox have promoted left-hander Michael Sansone from Low-A Salem to High-A Greenville, as was first reported by Hunter Noll of Beyond the Monster.

Sansone started the season in Salem’s bullpen after spending most of 2024 with Boston’s Carolina League affiliate. To open the 2025 campaign, the 25-year-old lefty posted a 2.75 ERA and 2.92 FIP with 22 strikeouts to just one walk in 10 relief appearances (19 2/3 innings) for the Red Sox. He converted two of his three save opportunities as opposing hitters batted .233 against him.

Among 85 Carolina League pitchers who entered play Tuesday having thrown at least 19 innings this year, Sansone ranked first in walks per nine innings (0.46) and walk rate (1.3 percent), fourth in WHIP (0.92) and xFIP (2.66), ninth in swinging-strike rate (16.1 percent), 13th in FIP, 16th in strikeout rate (29.3 percent), 19th in ERA, 26th in line-drive rate (19.2 percent), and 31st in strikeouts per nine innings (10.07), per FanGraphs.

Sansone began his professional career with the Rays organization after spending four years at Fairfield and going undrafted in July 2022. The Connecticut native made a handful of appearances in the Florida Complex League that summer and compiled a 3.49 ERA (3.10 FIP) in 15 relief outings (28 1/3 innings) for Tampa Bay’s Low-A affiliate the following season before being released in July 2023. He then signed with the Yolo High Wheelers of the independent Pioneer League last March, only to have his contract purchased by the Red Sox a few weeks later.

Sansone reported to Salem shortly thereafter and finished 2024 with a 3.11 ERA (3.25 FIP) in 20 appearances (three starts) spanning 72 1/3 innings. Altogether, the dimunitve southpaw owns a 3.14 ERA (3.16 FIP) with 127 strikeouts to just 15 walks over 120 1/3 career innings at the Low-A level dating back to April 2023, so one could say this is a well-earned promotion.

Standing at 5-foot-9 and 195 pounds, Sansone throws from a three-quarters arm slot and incorporates some deception into his delivery. Not known for his velocity, he primarily operates with a three-pitch mix that consists of an 88-90 mph fastball, an 83-84 mph slider and a 79-80 mph changeup, as noted in his SoxProspects.com scouting report.

Sansone, who turns 26 in November, is not currently ranked among Boston’s top 60 prospects by SoxProspects.com. In Greenville, he is slated to join a bullpen mix that, at present, includes fellow lefty Zach Fogell and righties Isaac Stebens, Matt McShane, Cooper Adams, Adam Smith, and Darvin Garcia.

Greenville’s series opener against Bowling Green on Tuesday was postponed due to inclement weather. It will be made up as part of a seven-inning doubleheader on Wednesday night.

Red Sox promote pitching prospect Tyler Uberstine to Triple-A Worcester

The Red Sox have promoted pitching prospect Tyler Uberstine from Double-A Portland to Triple-A Worcester, as was first reported by Andrew Parker of Beyond the Monster.

Uberstine, who turns 26 next month, opened the 2025 season in Portland’s starting rotation. The right-hander posted a 3.64 ERA (2.60 FIP) with a staff-leading 35 strikeouts to just four walks in six starts (29 2/3 innings) for the Sea Dogs. Opposing hitters batted .241 against him.

Among 30 qualified pitchers in the Eastern League coming into play on Thursday, Uberstine ranked second in walk rate (3.3 percent), third in walks per nine innings (1.21) and FIP, sixth in xFIP (2.90), seventh in strikeouts per nine innings (10.62) and WHIP (1.04), eighth in strikeout rate (29.2 percent), 11th in swinging-strike rate (12.6 percent), 12th in line-drive rate (20.8 percent), and 13th in groundball rate (42.9 percent), per FanGraphs.

A southern California native, Uberstine did not receive any scholarship offers out of Chaminade Prep in 2017, leading him to join the club baseball team after enrolling at USC. He attempted to walk on with the Trojans as a sophomore but was cut before the start of the season. That prompted him to seek out assistance from ex-big-leaguer Joe Biemel, who helped Uberstine refine his mechanics and add velocity to his repertoire.

Uberstine transferred to Northwestern for the final two seasons of his collegiate career and pitched for the Williamsport Crosscutters in the 2021 MLB Draft League. The righty was then selected by the Red Sox in the 19th round (556th overall) of that summer’s draft and signed for an under-slot $97,500 before making his professional debut in the Florida Complex League. He split the 2022 campaign between Low-A Salem and High-A Greenville but suffered an elbow injury the following spring that ultimately required June Tommy John surgery. As such, he missed all of 2023 and did not return to the mound until last August.

After making three short starts for Greenville, in which he allowed one earned run in 4 2/3 innings, Uberstine received an invite to pitch in the 2024 Arizona Fall League. He then forged a 3.12 ERA with seven strikeouts to six walks in seven appearances (8 2/3 innings) for the Mesa Solar Sox to end his year on an encouraging note.

“It was pretty surreal,” Uberstine told MLB.com’s Jesse Borek in Arizona last November. “They threw me out in Greenville again, where I played in ‘22, and then I was like, ‘Hopefully I can get a couple more innings. The quality would be great.’ [The Fall League] is where the best players come, and when they called me in the office and mentioned it, it was just a huge moment.

“I was like, ‘Dang, I went from not playing baseball to playing in the Draft League and here I am now playing in the Fall League,’” Uberstine added. “Just having these opportunities to learn from so many people, players, coaches, it’s just a huge honor.”

Fast forward to the present, and Uberstine is currently regarded by SoxProspects.com as the No. 56 prospect in Boston’s farm system, which ranks 30th among pitchers in the organization. To this point in the season, the 6-foot-1, 200-pound hurler has sat between 91-94 mph and reached 95 mph with his fastball. He has also featured an 86-89 mph cutter, an 81-84 mph slider, and an 84-86 mph changeup, according to SoxProspects.com director of scouting Ian Cundall.

Having last pitched on May 10, Uberstine is expected to make his Triple-A debut by getting the start for the WooSox in the penultimate game of their series on the road against the Buffalo Bisons this coming Saturday. He is another minor-leaguer who can become Rule 5-eligible this winter if he is not added to Boston’s 40-man roster by the November protection deadline, so that could be something to keep in mind when evaluating his performance moving forward.
