Boston Red Sox

Roman Anthony

LF

Anthony was injured on a check-swing and had to be removed from Tuesday's Game 1 loss to the Yankees. He drove back to Boston after the contest for imaging, which revealed the bad news. Anthony is now ineligible to play before the ALCS, and there's a good chance he is done for the rest of the postseason, regardless of how far the Red Sox advance. Manager Chad Tracy said that Anthony Seigler and Curtis Mead (hand) are the top candidates to take Anthony's spot on the roster.

Mickey Gasper

DH

Gasper's biceps tendon tore completely off the bone on a swinging strikeout during a Sept. 25 contest against the Cubs. He will be unavailable for the entirety of the postseason, and it's unclear how long the rehab process will take. Assuming health, Gasper should be in the mix for a utility role with the Red Sox again next season after slashing .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.

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).

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.

Anthony Seigler

2B

Seigler's wrist injury flared up during Saturday's game against the Royals, and further tests have revealed that the injury is severe enough for him to spend time on the IL. Isiah Kiner-Falefa and Nick Sogard will be the main depth infield options for Boston while Seigler is on the IL. In a corresponding move, Willson Contreras (hamstring) was reinstated from the 10-day injured list.

Kristian Campbell

OF

While the injury seems relatively minor, there's a chance it will end Campbell's season, anyway, given how little of the schedule is left. Campbell put up a .631 OPS with just two home runs through the end of June at Worcester this season, but he's slashed .320/.440/.524 with six long balls since July 1.

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.

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.

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.
