Boston Red Sox

Caleb Durbin

3B

The 26-year-old dealt with a dislocated pinkie over the summer, but he played through the injury and never went on the injured list. Durbin struggled early in 2026 but bounced back with a .738 OPS during the second half, resulting in a .248/.332/.378 slash line with 13 homers and 20 steals in 153 regular-season games. He'll likely be fully healthy for the start of spring training since he has three-plus months to recover from the procedure.

Garrett Whitlock

RP

Whitlock hasn't been charged with a run over his last 6.2 innings, picking up two saves, four holds and a blown save in that span. He got the save chance after the Red Sox took the lead in the eighth inning. Aroldis Chapman was deemed unavailable to due a lat issue, which the Red Sox are approaching with caution. Whitlock has thrived as a reliever this year with a 1.78 ERA, 0.83 WHIP and 58:8 K:BB while adding four saves, 25 holds and four blown saves over 50.2 innings. He should be in line for more save chances if they arise before Chapman is cleared to return to the mound.

Roman Anthony

LF

Breslow noted that the club is still gathering information on Anthony, who suffered an aggravation and additional injuries to his right hand during Game 1 of the wild-card series versus the Yankees. However, the feeling at this time is that Anthony's injury will heal with rest. Anthony was limited to only 55 regular-season contests in 2026 because of finger and hand problems.

Tyron Guerrero

RP

Guerrero missed most of September with right shoulder inflammation before returning to the active roster Sept. 20. He's now dealing with more shoulder trouble, and it's uncertain if he might be able to return in October should the Red Sox advance deep in the playoffs. Guerrero has been a reliable arm for Boston this season, posting a 3.10 ERA and 1.11 WHIP with 18 holds across 40.2 innings (40 appearances).

Masataka Yoshida

DH

Yoshida was placed on the 10-day injured list Sunday due to the hamstring strain, with the hope he could return by early September. However, it now appears Yoshida could potentially miss the rest of the regular season. Yoshida is set to get multiple opinions and imaging done in coming days to evaluate his best course of action.

Mickey Gasper

DH

The 4-to-6 month timeline is for Gasper's return to game action, so there's a good chance he'll be held out of spring training action initially, and his availability for Opening Day isn't a given. Gasper slashed .251/.357/.466 with 10 home runs and a 27:39 BB:K over 67 games in 2026.

Romy Gonzalez

DH

Gonzalez will head back to the minors to help make room on the active roster for the additions Boston made prior to the trade deadline. The 29-year-old utility man has taken a step back in the big leagues this year, slashing just .185/.264/.308 with seven RBI and seven runs scored in 73 plate appearances.

Justin Slaten

RP

The transaction makes space for the return of Garrett Crochet (lat) from the 60-day IL. Slaten had previously been ruled out for the remainder of the season after getting a platelet-rich plasma injection to address degenerative changes in his flexor mass.

Eli White

CF

A 40-man spot was needed for the returning Tanner Houck (elbow), and this was the logical move with White having recently undergone Lisfranc surgery on his right foot. White ends the 2026 regular season with a .246/.289/.398 slash line, six homers, 29 RBI, 27 runs scored and five stolen bases across 204 major-league plate appearances between Atlanta and Boston.

Johan Oviedo

SP

Ovideo, who began a rehab assignment with the WooSox, threw 30 pitches (20 strikes). It's unlikely he throws again for Worcester, which has been eliminated from the Triple-A International League postseason. That leaves a potential return to Boston, where Ovideo could operate as a multi-inning arm out of the bullpen.

Kutter Crawford

SP

The Red Sox announced around the All-Star break that Crawford had resumed playing catch at a distance of approximately 100 feet, but news has been scarce on the right-hander ever since. After his 2025 season came to an early end due to right wrist surgery, Crawford was further set back in the spring by the flu. He opened the season on the injured list and appeared to be in line for just a brief absence, but he was pulled off a rehab assignment in mid-April after experiencing right flexor irritation and experienced renewed tightness in his forearm in early June. Though he's under club control through 2028, he could be a non-tender candidate this winter after having essentially two straight seasons lost to injury.

Eduardo Rivera

SP

The left-hander landed on Worcester's 7-day injured list in late August due to the injury, and his transition to the MLB 60-day IL will bring an end to his 2026 regular season. Rivera made his first four big-league appearances this year and had a 6.30 ERA, 1.40 WHIP and 10:6 K:BB in 10 innings.

Triston Casas

1B

The Red Sox did not offer a timeline for Casas' recovery, but the procedure undoubtedly will end his season. It's another lost year for Casas, who played only 29 games in 2025 and zero in 2026 due to a ruptured patellar tendon, a left intercostal strain and now a wrist problem. Casas will be eligible for salary arbitration for a second time this offseason.

Zack Kelly

RP

The right-hander landed on the 7-day IL at Worcester in early July due to elbow inflammation, and he'll now be sidelined until at least early September. The severity of the injury isn't clear, but it's possible that Kelly has already thrown his last competitive pitch of the season.
