The Red Sox selected De Leon's contract from Triple-A Worcester, and he will start Sunday's regular-season finale against the Tigers, Chris Cotillo of MassLive.com reports.

With the Red Sox locked into a wild-card spot and not in contention for the AL East title, they will give De Leon his first big-league opportunity since 2023. Chris Murphy was optioned in a corresponding move. De Leon put up a 6.93 ERA and 1.73 WHIP in 75.1 innings with Worcester this season.

Blue Jays manager John Schneider said Sunday that it's "pretty unlikely" that Bichette (knee) would be available if Toronto plays in the wild-card round of the playoffs, Ben Nicholson-Smith of Sportsnet.ca reports.

Bichette is taking part in some activity, including light hitting and throwing, but he's still not running, per Keegan Matheson of MLB.com. A left knee sprain put Bichette on the injured list back on Sept. 9. The Blue Jays can clinch the AL East title and a first-round bye with a win or a Yankees loss Sunday.

Chisholm (forearm) is not in the starting lineup for Sunday's game against the Orioles.

The AL East crown is still up for grabs, but Chisholm won't be in the lineup after being hit in the left forearm by a pitch in the fifth inning of Saturday's 6-1 win. X-rays were negative, however, and Chisholm said he considers himself available off the bench Sunday even while he's still dealing with some swelling and soreness, per Gary Phillips of the New York Daily News. With 31 homers and 31 steals on the campaign, Chisholm is one of seven players to join the 30-30 club this season.

The Twins optioned Ohl to Triple-A St. Paul on Sunday.

Ohl finished his season with eight scoreless innings spanning his final six appearances, including two scoreless frames during Saturday's win over Philadelphia. The Twins cleared him out to make room for the return of Anthony Misiewicz (pectoral) from the injured list.

Buxton is not in the lineup for Sunday's game against the Phillies.

Buxton will take a seat for the Twins' final game of 2025, ceding center field to James Outman with Ryan Jeffers at DH. Austin Martin will move up to the leadoff spot against lefty Cristopher Sanchez. Buxton homered in Saturday's win, his fourth homer in as many games and career-high 35th of the season.

The Twins reinstated Misiewicz (pectoral) from the 15-day injured list Sunday.

Misiewicz has been shelved for more than three months due to a left pectoral strain, but he will presumably get some work in during Sunday's regular-season finale, which should at least provide him with some peace of mind heading into the winter. Misiewicz has allowed five runs on four hits and three walks while striking out five over 4.1 major-league innings so far this season.

Gimenez is not in the lineup for Sunday's game against the Rays.

Ernie Clement will start at shortstop while Davis Schneider mans second base with lefty Ian Seymour toeing the rubber for Tampa Bay in the regular-season finale. Gimenez is slashing a woeful .172/.229/.234 in September, but he has nonetheless maintained a regular role against right-handed pitching to close out the campaign.

Kelly allowed no hits and a walk with no strikeouts over a scoreless inning in Saturday's 4-2 loss against the Royals.

Kelly worked a scoreless seventh inning while issuing just a walk to Mike Yastrzemski. The right-hander has been excellent in September, posting a 1.93 ERA and 0.96 WHIP over 11 outings, including seven straight appearances without an earned run -- his longest streak since opening the year with 10 consecutive scoreless frames. Overall, the 33-year-old owns a 2.75 ERA and 1.25 WHIP across 41 appearances and 39.1 innings this season.

Alvarado allowed no hits and a walk with no strikeouts over 1.1 scoreless innings Saturday against Kansas City.

Alvarado entered in the fifth inning and recorded the final out of the frame, then worked through the sixth while allowing just one baserunner. The hard-throwing righty has been sharp down the stretch, tossing 6.1 scoreless innings over his past five appearances and posting a 1.86 ERA across nine outings in September. In his rookie season, he owns a 3.27 ERA and 1.33 WHIP across 36 appearances and 41.1 innings.

Burke did not factor into the decision Saturday against the Nationals, allowing two runs on three hits and a walk across 4.1 relief innings. He struck out 10.

Working in a bulk role, Burke logged a season-high 10 punchouts while allowing just a pair of runs on a Daylen Lile homer. The 25-year-old Burke was solid down the stretch, posting a 3.65 ERA over his last three appearances (12.1 innings). He'll finish the year at 4-11 with a 4.29 ERA, 1.45 WHIP and 133 strikeouts across 134.1 innings.
