Seymour is slated to start Sunday's game in Toronto.

In his most recent appearance Tuesday, Seymour ended up piggybacking starter Ryan Pepiot and covered four innings while allowing three earned runs on four hits and two walks. Seymour will return to a traditional starting role for the season finale and will look to finish the campaign on a high note as he makes a case for a spot in the 2026 rotation. Since being called up from Triple-A Durham on July 31, Seymour has logged a 3.14 ERA, 1.09 WHIP and 48:14 K:BB in 43 innings over 11 outings.

The Red Sox optioned Murphy to Triple-A Worcester on Sunday.

Murphy threw three scoreless innings in Saturday's loss to Detroit, bringing his ERA and WHIP down to 3.12 and 1.18, respectively, over 34.2 innings with the big club this season. Jose De Leon was called up from Triple-A in a corresponding move and will start the Red Sox's regular-season finale versus the Tigers. Murphy will likely stay active in case he's needed out of the bullpen at some point in the postseason.

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.

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.

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.

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.

Basso will serve as the Athletics' opening pitcher in Sunday's game against the Royals, Martin Gallegos of MLB.com reports.

The Athletics won't have Jeffrey Springs make his normally scheduled start in the season finale, so Basso will take the mound first in what's expected to be a bullpen day. Basso made four starts for the Athletics in 2024 but has worked exclusively as a reliever in 2025. He's eclipsed two innings in just one of his 18 appearances between the majors and minors this season, so he's unlikely to work more than once through the batting order Sunday.

Estevez struck out two and hit a batter while pitching a scoreless inning to earn the save in Saturday's 4-2 win over the Athletics.

This was Estevez's 42nd save of the season, ensuring he would finish first in the majors in the category -- he's two ahead of San Diego's Robert Suarez with one day left in the campaign. Opportunities have been limited for Estevez in September, as he's collected saves in six of his seven appearances for the month. The right-handed closer is at a 2.45 ERA, 1.06 WHIP and 54:22 K:BB across 66 innings this year.

Blubaugh allowed a hit and four walks while striking out two over four scoreless innings in a no-decision versus the Angels on Saturday.

Blubaugh threw just 35 of 70 pitches for strikes, but the Angels weren't able to take advantage. He kept runs off the board in his last eight appearances, spanning 19 innings in which he had a 20:8 K:BB. The 25-year-old posted a 1.69 ERA, 0.88 WHIP and 35:11 K:BB over 42 innings across 11 appearances (three starts) in his first taste of major-league action, which is much more impressive than his 5.27 ERA and 101:58 K:BB over 99 innings with Triple-A Sugar Land this year.
