Red Sox add trio of pitching prospects to 40-man roster ahead of Rule 5 deadline

The Red Sox added three pitching prospects — right-handers David Sandlin and Tyler Uberstine and left-hander Shane Drohan — to their 40-man roster in advance of Tuesday’s Rule 5 Draft protection deadline.

To accommodate the additions of Sandlin, Uberstine, and Drohan, the Red Sox traded left-handers Brennan Bernardino and Chris Murphy to the Rockies and White Sox, respectively, for a pair of minor leaguers and designated righty Josh Winckowski for assignment.

Sandlin is currently regarded by MLB Pipeline as Boston’s No. 10 prospect, which ranks sixth among pitchers in the organization. The hard-throwing 24-year-old was originally selected by the Royals in the 11th round of the 2022 draft out of Oklahoma, then acquired by the Red Sox for reliever John Schreiber last February.

Sandlin opened the 2025 season with Double-A Portland, pitching to a 3.61 ERA (3.33 FIP) with 86 strikeouts to 27 walks over 17 outings (13 starts) spanning 82 1/3 innings in which he held opposing hitters to a .227 batting average. He received a promotion to Triple-A Worcester in late July but then struggled to a 7.61 ERA (5.27 FIP) in 15 appearances (one start) totaling 23 2/3 innings as he transitioned to a bullpen role ahead of a possible big league call-up.

That never came to fruition, but there is still plenty to like about Sandlin when it comes to his arsenal. The 6-foot-4, 215-pound hurler sits at 94-97 mph and reaches triple digits with his fastball. while also incorporating a slider, sweeper, splitter, and curveball into a diverse pitch mix.

Uberstine, a one-time USC hopeful who did not receive any scholarship offers coming out of high school, was Boston’s 19th-round pick in the 2021 draft out of Northwestern. After working his way back from June 2023 Tommy John surgery late last season, the 26-year-old opened the 2025 campaign at Portland and posted a 3.64 ERA (2.51 FIP) with 35 strikeouts to just four walks in six starts (29 2/3 innings) before receiving a promotion to Worcester in mid-May. From there, he forged a 3.56 ERA (4.92 FIP) with 102 strikeouts to 37 walks across 19 outings (15 starts) and 91 innings in which opponents batted .245 against him.

Altogether, Uberstine finished the season leading the Red Sox organization in innings pitched (120 2/3) and strikeouts (137). The 6-foot-1, 200-pound righty features a 92-94 mph fastball that tops out at 95 mph as well as a slider, a changeup, a cutter, and a curveball.

Unlike Sandlin and Uberstine, Drohan is already plenty familiar with the Rule 5 process. Boston’s fifth-round pick in the 2020 draft out of Florida State, the 26-year-old Drohan was left off the club’s 40-man roster when first eligible following the 2023 season and was subsequently scooped up by the White Sox in the Rule 5 Draft that December. He was, however, later returned to the Red Sox in June 2024 after undergoing a nerve decompression procedure in his left shoulder four months prior.

Drohan began the 2025 season in Worcester but was limited to 12 outings (11 starts) with Boston’s top affiliate due to left forearm inflammation that sidelined him from early May until late August. When on the mound, though, the 6-foot-3, 195-pound southpaw compiled a 2.27 ERA (2.85 FIP) with 67 strikeouts to 16 walks over 47 2/3 innings in which he held opposing hitters to a .185 batting average. He primarily operates with a 92-94 mph fastball that can reach 96 mph, a changeup, a curveball, a cutter, and a slider.

With the additions of Sandlin, Uberstine, and Drohan, the Red Sox now have a full 40-man roster. That means that other eligible prospects who were left off, like righties Yordanny Monegro (who is recovering from Tommy John surgery) and Jedixson Paez, lefties Eduardo Rivera and Hayden Mullins, and outfielders Miguel Bleis and Allan Castro, could be taken by other clubs in next month’s Rule 5 Draft.

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.

Red Sox to send eight minor-leaguers to Arizona Fall League

The Red Sox will send eight minor-leaguers — five pitchers and three position players — to the Arizona Fall League this year.

Left-hander Zach Fogell, right-handers Cooper Adams, Danny Kirwin, Conor Steinbaugh, and Tyler Uberstine, catcher Brooks Brannon, infielder Max Ferguson, and outfielder Caden Rose were named to the Mesa Solar Sox’ preliminary 2024 roster on Wednesday. They are slated to play alongside prospects from the Angels, Athletics, Cubs, and Rays organizations.

Of the eight that make up the Red Sox’ contingent, Brannon is perhaps the most notable. The 20-year-old is currently regarded by MLB Pipeline as the No. 27 prospect in Boston’s farm system. He was originally selected in the ninth round of the 2022 draft out of Randleman High School (N.C.) and forwent his commitment to the University of North Carolina by signing for an over-slot $712,500.

After a low back strain limited him to just 17 games last year, Brannon opened the 2024 campaign on the 60-day injured list due to a knee issue. The right-handed-hitter spent a few weeks rehabbing in the Florida Complex League before joining Low-A Salem in early June. He then batted .251/.326/.396 with eight doubles, two triples, six home runs, 24 RBIs, 22 runs scored, five stolen bases, 23 walks, and 67 strikeouts in 54 games (230 plate appearances) for the Red Sox. From behind the plate, he threw out 13 of 69 possible base stealers.

Sticking with the position players, Ferguson missed much of the season with an ankle injury that sidelined him for more than four months. In 28 games between Double-A Portland and Triple-A Worcester, the left-handed hitting 25-year-old slashed just .152/.255/.272 with two doubles, three home runs, 11 RBIs, 14 runs scored, six stolen bases, 13 walks, and 30 strikeouts over 106 plate appearances. He was originally selected by the Padres in the fifth round of the 2021 draft out of Tennessee but was traded to the Red Sox with Eric Hosmer and Corey Rosier for Jay Groome the following August.

Rose, like Brannon and Ferguson, also spent time on the 60-day injured list this season after being taken by the Red Sox in the seventh round of the 2023 draft out of Alabama. The right-handed hitting 22-year-old struggled out of the gate for High-A Greenville (.619 OPS in 25 games) but posted a .353/.476/.529 line with six doubles, seven RBIs, nine runs scored, three stolen bases, five walks, and 10 strikeouts in 10 games (42 plate appearances) for Salem upon returning to action late last month.

On the pitching front, Uberstine stands out given the fact that he only recently returned to the mound after undergoing Tommy John surgery last June. A former 19th-round draft selection out of Northwestern in 2021, the 25-year-old joined Greenville in late August and allowed one earned run on five hits, one walk, and six strikeouts in three starts (4 2/3 innings) for the Drive. He was promoted to Portland on September 10 but spent the rest of the season on the Sea Dogs’ development list.

Fogell, Boston’s 18th-round selection in the 2023 draft out of Connecticut, spent much of his first full professional season with Greenville after being promoted from Salem in early April. In 33 appearances for the Drive, the 24-year-old Rhode Island native posted a 3.32 ERA and 4.52 FIP with 67 strikeouts to 32 walks over 57 innings of relief in which he held opposing hitters to a .212 batting average.

Adams, Kirwin, and Steinbaugh signed with the Red Sox as undrafted free agents in February, April, and March, respectively. Adams, 24, posted a 5.08 ERA (5.48 FIP) with 59 strikeouts to 37 walks in 26 outings (six starts) spanning 79 2/3 innings for Greenville. Kirwin, also 24, produced a 3.63 ERA (3.65 FIP) with 69 strikeouts to 24 walks in 20 outings (five starts) spanning 69 1/3 innings for Salem. Steinbaugh, 25, was assigned to Salem from Greenville in early May and put up a 2.86 ERA (3.65 FIP) with 52 strikeouts to 19 walks in 20 appearances (one start) spanning 56 2/3 innings after that.

In addition to sending eight players, the Red Sox will be dispatching one coach and one athletic trainer to Arizona as well. Sean Isaac, who has served as Portland’s pitching coach in each of the last two seasons, was named to Mesa’s coaching staff under manager Andy Schatzley. Marissa Sciabarra, who has served as Boston’s Florida Complex League athletic trainer in each of the last two seasons, was named to the Solar Sox’ support staff.

The 2024 Arizona Fall League regular season begins on October 7 and runs through November 14. The annual Fall Stars game is scheduled for November 9 while the championship game will be held on November 16 at Salt River Fields in Scottsdale.

Red Sox drafted 8 pitchers in 2021; how did each of them fare during first full pro season?

The Red Sox selected and signed eight pitchers in the 2021 amateur draft. Of those eight, seven were taken out of college, one was taken out of high school, and one has yet to make his professional debut.

For the vast majority of these pitchers, the 2022 minor-league campaign represented their first full seasons in pro balls. Here is a rundown of how each of them fared this year, beginning with the highest draft pick and ending with the lowest one.

Elmer Rodriguez-Cruz, RHP (4th round, 105th overall pick)

Taken out of Leadership Christian Academy in Puerto Rico, Rodriguez-Cruz forwent his commitment to the University of Oregon by signing with Boston for $497,500. The 19-year-old right-hander made his pro debut in the Florida Complex League this summer and posted a 1.95 ERA with 36 strikeouts to 12 walks over 11 appearances (8 starts, 32 1/3 innings) before earning a promotion to Low-A Salem in late August. He then allowed one run while striking out six and walking three in two starts (6 innings) with the Salem Sox.

Listed at 6-foot-3 and 160 pounds with room to grow, Rodriguez-Cruz throws from a three-quarters arm slot and operates with a four-pitch mix that consists of a 90-93 mph fastball that tops out at 95 mph, a 75-78 mph curveball, an 80-83 mph changeup, and a slider that is considered to be a work in progress. He is currently regarded by SoxProspects.com as the No. 19 prospect in Boston’s farm system.

Wyatt Olds, RHP (7th round, 196th overall pick)

Olds, 23, broke camp with High-A Greenville this spring after ending the 2021 season in Salem. The University of Oklahoma product forged a 6.01 ERA with 130 strikeouts to 50 walks over 26 outings (25 starts) and 106 1/3 innings for the Drive. He also made one start for Double-A Portland in September and allowed two earned runs across 4 2/3 innings of work.

At 6-foot and 183 pounds, Olds pitches exclusively from the stretch and possesses a 93-96 mph fastball that tops out at 98 mph, an 85-88 mph slider, and an 87-89 mph changeup, per his SoxProspects.com scouting report. He is currently regarded by the site as the No. 56 prospect in the organization.

Hunter Dobbins, RHP (8th round, 226th overall pick)

Sliding in right ahead of Olds in SoxProspects.com’s year-end rankings is Dobbins. The Texas Tech product missed the entirety of the 2021 season after undergoing Tommy John surgery last March and signed with Boston for $197,500 four months later. After making a full recovery from the procedure, Dobbins debuted with the Salem Red Sox back in June. He compiled a 5.22 ERA — but much more respectable 3.76 xFIP — with 68 strikeouts to 22 walks over 17 starts spanning 69 innings pitched.

Dobbins, also 23, is listed at 6-foot-2 and 185 pounds. The former Red Raider works with a four-pitch arsenal that includes a 91-94 mph heater that tops out at 96 mph, a 74-78 mph curveball, an 83-85 mph changeup, and a high-80s slider that is used sparingly, according to SoxProspects.com. He is projected by the site to make the jump to Greenville next spring.

Matt Litwicki, RHP (10th round, 286th overall pick)

Litwicki is the one pitcher in this draft class who has yet to take the mound in an organized game. The 24-year-old righty was limited to just 31 1/3 innings at Indiana University (missed the entire 2018 season after undergoing Tommy John surgery, missed time in 2021 because of back and shoulder injuries) and received a $47,500 signing bonus from the Sox.

Per SoxProspects.com, Litwicki suffered a setback while rehabbing earlier this year and wound up missing the entirety of the 2022 campaign as a result. When healthy, the 6-foot-2, 220-pound hurler has shown that he can reach 99 mph with his four-seamer while also mixing in a low-80s slider. As of now, it remains to be seen if Litwicki is on track to be ready for spring training.

Christopher Troye, RHP (12th round, 346th overall pick)

Troye, who turns 24 in February, received a $122,500 signing bonus from Boston after spending four years (and undergoing Tommy John surgery in 2020) at the University of California, Santa Barbara. The Brentwood native missed the first month or so of the 2022 season with an undisclosed injury, but he made his way to Salem by mid-May.

In 26 relief appearances for the Red Sox, Troye produced a 4.86 ERA (3.10 FIP) with 50 strikeouts to 24 walks over 33 1/3 innings of work. His 35 percent punchout rate ranked ninth among Carolina League pitchers who accrued at least 30 innings, though his 16.8 percent walk rate was the 16th-highest in the league using that same parameter.

Given that he has the ability to strike out hitters and miss bats at a high rate, it should come as no surprise that Troye possesses tantalizing stuff. The 6-foot-4, 225-pounder sits in the mid-90s with his fastball and can reach 99 mph with the pitch, according to SoxProspects.com. He also flashes a 12-6 curveball, but has shown that he can struggle with his command at times. How he works to improve that will likely play a key role in his development moving forward.

Jacob Webb, RHP (14th round, 406th overall pick)

Webb may be the furthest along of any pitcher listed here. The 23-year-old righty out of Miami University of Ohio pitched across three different levels this season and made it as far as Portland. He posted a 3.18 ERA with 88 strikeouts to 28 walks in 44 total appearances (56 2/3 innings) between Salem, Greenville, and Portland before heading out west to pitch in the Arizona Fall League. With the Scottsdale Scorpions, Webb yielded four earned runs over 10 innings of relief while fanning 12 of the 41 batters he faced.

Listed at a burly 6-foot-5 and 246 pounds, Webb is currently ranked by SoxProspects.com as the No. 60 prospect in Boston’s farm system. The Dayton native operates with a three-pitch mix that consists of a 94-96 mph heater that can reach 98 mph, an 82-84 mph slider, and an 88-90 mph changeup. He is projected to return to the Sea Dogs bullpen for the start of the 2023 season.

Luis Guerrero, RHP (17th round, 496th overall pick)

The lone junior college pitcher included here, Guerrero turned in a solid 2022 campaign after not pitching professionally in 2021. The 22-year-old right-hander out of Chipola College appeared in a total of 27 games between the FCL, Salem, and Greenville. He produced a 3.23 ERA with 59 punchouts to 17 walks over 39 combined innings of work. That includes a 2.08 ERA (1.66 FIP) in seven outings with the Drive.

Originally from the Dominican Republic, Guerrero is listed at 6-foot and 215 pounds. The Bani native can reach triple digits with his four-seam fastball and also possesses an 83-85 mph splitter, an 88-91 mph slider, and a 75-79 mph curveball, per his SoxProspects.com scouting report. He is currently regarded by the site as the 34th-ranked prospect in the system.

Tyler Uberstine, RHP (19th round, 556th overall pick)

A former member of the University of Southern California’s club baseball team, Uberstine transferred to Northwestern University in 2020 and has only seen his stock rise since then. This past season, the 23-year-old righty posted a 3.83 ERA with 101 strikeouts to 35 walks over 21 combined appearances (15 starts, 91 2/3 innings) between Salem and Greenville. He pitched well for the Drive (2.43 ERA) after being promoted in July, but was limited to just seven starts from that point forward due to a quad strain.

Uberstine, who turns 24 in June, is currently regarded by SoxProspects.com as the No. 32 prospect in Boston’s farm system. The 6-foot-1, 200-pound hurler works with a 92-94 mph fastball that tops out at 95 mph, an 85-87 mph changeup, and an 83-85 mph slider, according to the site’s scouting report on him.

Red Sox promote pitching prospect Tyler Uberstine to High-A Greenville

The Red Sox have promoted pitching prospect Tyler Uberstine from Low-A Salem to High-A Greenville, per the team’s minor-league transactions log.

Uberstine, 23, is currently regarded by SoxProspects.com as the No. 38 prospect in Boston’s farm system, ranking 16th among pitchers in the organization. The Red Sox originally selected the right-hander in the 19th round of last year’s draft out of Northwestern University and signed him for $97,500.

After pitching in the MLB Draft League and rookie-level Florida Complex League last summer, Uberstine began his first full season in pro ball with Salem. In 14 starts (eight appearances) for the Red Sox, the California native posted a 4.63 ERA — but much more respectable 3.87 FIP — to go along with 66 strikeouts to 21 walks over 58 1/3 innings of work.

Among Carolina League pitchers who have thrown at least 50 innings to this point in the season, Ubserstine ranks 18th in strikeouts per nine innings (10.18), 14th in walks per nine innings (3.24), 15th in walk rate (8.4%), 18th in swinging strike rate (14%), 12th in groundball rate (49.1%), 16th in FIP, and eighth in xFIP (3.53), per FanGraphs.

Listed at 6-foot-1 and 200 pounds, Uberstine throws from a three-quarters arm slot and works with a three-pitch mix that consists of a 91-93 mph fastball that tops out at 95 mph, a changeup, and a slider, according to his SoxProspects.com scouting report.

Uberstine becomes the latest member of Boston’s 2021 draft class to get called up to Greenville, joining the likes of Wyatt Olds, Jacob Webb, Nathan Hickey, Niko Kavadas, Tyler McDonough, and Phillip Sikes.

In order to make room on the roster for Uberstine, the Drive transferred fellow righty Chih-Jung Liu to the development list.
