Yoshida underwent surgery Oct. 3 to repair a labral tear in his right shoulder, Ian Browne of MLB.com reports.

The hope is that Yoshida will be ready in time for Opening Day, although it's not clear how limited, if at all, he will be during spring training. Yoshida slashed .280/.349/.415 with 10 home runs over 108 games for Boston this season as its full-time designated hitter.

Cowser had successful surgery on his fractured hand Tuesday, Andy Kostka of TheBaltimoreBanner.com reports.

Cowser fractured his left hand in Game 2 of the American League Wild Card Series versus the Royals on Oct. 2, the game in which the Orioles were eliminated. Given the timing of the injury, Cowser is expected to have enough recovery time to be ready for the start of spring training.

Yamamoto will start Thursday in Game 4 of the NLCS against the Mets, Fabian Ardaya of The Athletic reports.

Yamamoto was able to bounce back in Game 5 of the NLDS by throwing five shutout frames against the Padres after he had given up five runs in just three innings during Game 1. He'll now be tasked with keeping quiet a Mets offense that owns a .698 OPS since the start of the postseason.

Manager Dave Roberts said he expects Lux (hip) to be back in the lineup Wednesday for Game 3 of the NLCS, Matthew Moreno of DodgerBlue.com reports.

Lux was absent from the lineup in Game 2 after being removed from Game 1 due to hip-flexor tightness. The second baseman is 5-for-19 with a home run and two walks in the 2024 postseason. If he is back in the lineup as expected Wednesday, he will be facing Mets' right-handed starter Luis Severino.

Mets manager Carlos Mendoza on Tuesday confirmed that Quintana will start Thursday in Game 4 of the NLCS versus the Dodgers, Anthony DiComo of MLB.com reports.

Quintana has permitted just one unearned run over 11 innings in two starts this postseason, and, including those two outings, boasts a 0.57 ERA across his last eight starts dating back to late August. He will be opposed by Yoshinobu Yamamoto.

Mets manager Carlos Mendoza said Tuesday that Martinez will likely be in the lineup Wednesday in Game 3 of the NLCS, Bob Nightengale of USA Today reports.

Jesse Winker started at designated hitter in each of the first two games of the series, going 2-for-6 with a 2:2 K:BB. The Dodgers are slated to start another right-hander, Walker Buehler, in Game 3, but it sounds like Martinez will receive his first start of the series. The veteran is 4-for-14 with three RBI and a 4:2 K:BB so far this postseason.

The Guardians added Lively to their ALCS roster Tuesday.

He's taking the roster spot vacated by Alex Cobb, who is now out for the remainder of the postseason with a back injury. Lively hasn't made an appearance since his final start of the regular season back on Sept. 28, but he's a candidate to make a start during the ALCS in Cobb's place.

The Guardians removed Cobb from their ALCS roster due to an acute left low-back strain.

Cobb lasted 2.2 innings in his Game 1 start against the Yankees, getting charged with three runs on five hits and three walks. Because he's being removed from the roster due to injury, he is now ineligible for the World Series, should the Guardians advance. Ben Lively has absorbed Cobb's roster spot and might also get an ALCS start in his place.

Stratton (forearm) is expected to be healthy for the beginning of spring training, Anne Rogers of MLB.com reports.

Stratton missed the final couple weeks of the regular season and the playoffs with a right flexor strain, but he's expected to recover with an offseason of rest. The veteran reliever holds a $4.5 million player option for 2025, which he seems likely to exercise after posting a lackluster 5.55 ERA and 44:33 K:BB over 58.1 innings in 2024.

McArthur (elbow) is expected to be ready for the start of spring training, Anne Rogers of MLB.com reports.

McArthur was diagnosed with a Grade 1 UCL sprain in his right elbow in mid-September, resulting in a premature end to his season. While a Grade 1 sprain is the least severe, there is always going to be some long-term concern when UCL damage is involved. For now, though, the expectation is McArthur will be ready for spring training after some rest and rehab.
