Fitts is slated to start Wednesday's game against the Blue Jays in Toronto.

After making a spot start Sept. 13 while Tanner Houck dealt with shoulder fatigue, Fitts ended up sticking in the rotation for another turn this past Friday versus the Twins. Fitts was denied a win, but he tossed five scoreless innings in the contest and now appears to have solidified a spot as the Red Sox's No. 5 starter over Cooper Criswell, who was optioned to Triple-A Worcester on Saturday. Fitts' upcoming start Wednesday will likely mark his final outing of the season, and he'll look to end the campaign on a high note as he aims to stake a claim to a rotation spot heading into 2025.

Manager Alex Cora told reporters Sunday that Jansen is likely to be placed on the 15-day injured list Monday due to a right shoulder injury, Chris Cotillo of MassLive.com reports.

Jansen has been battling through a nagging right shoulder issue over the past week, and the 36-year-old closer is set to be shut down for the rest of the regular season. Chris Martin and Justin Slaten will handle the closing duties for the final games of the regular season with Jansen sidelined. Jansen finishes his second year in Boston with 27 saves while registering a 3.35 ERA, 1.08 WHIP and 61:20 K:BB across 53.2 innings, and he will be a free agent this offseason.

Weaver struck out three over 1.2 perfect innings to earn the save in Sunday's 7-4 win over the Athletics.

Clay Holmes struggled in the eighth inning, but Weaver was able to escape without trouble. Weaver then stayed in for the ninth to close out the contest and earn his fourth save, all of which have come over his last seven appearances. Weaver is now at a 2.93 ERA, 0.93 WHIP and 101:26 K:BB over 83 innings this season, and he continues to pitch in the highest-leverage moments.

Munoz (3-7) allowed a run on two hits and struck out one over two-thirds of an inning, taking the loss Sunday versus the Rangers.

It wasn't a save situation, but Munoz wasn't able to keep the game tied at 5-5 in the ninth inning, instead taking a walk-off loss. He entered Sunday on a five-inning scoreless streak before this hiccup. Munoz has maintained a 2.16 ERA, 0.96 WHIP and 76:26 K:BB over 58.1 innings while adding 22 saves in 27 chances and six holds this season.

Yates (7-2) struck out one over a perfect inning to earn the win Sunday over the Mariners.

Yates kept the game tied in the top of the ninth inning, and the Rangers walked it off in their half of the frame. Over his last 13.1 innings, Yates has allowed one run while posting an 18:5 K:BB and earning 10 saves and three wins. He's at a 1.21 ERA, 0.84 WHIP and 84:27 K:BB across 59.2 innings while going 31-for-32 in save chances this season.

Wilson (back) was returned from his rehab assignment Sunday due to right shoulder impingement syndrome, Scott Merkin of MLB.com reports.

Wilson was originally forced to the injured list in mid-August due to a lower-back strain. He appeared to be closing in on a return, having made eight appearances during his rehab stint with Triple-A Charlotte, but the shoulder impingement will bring an early end to his campaign. Wilson posted a 5.71 ERA, 1.59 WHIP and 34:26 K:BB over 34.2 innings in his first season with the White Sox.

Manager Aaron Boone said Sunday that Trivino (elbow) has been shut down due to "shoulder stuff," Bryan Hoch of MLB.com reports.

Trivino had been working his way back from Tommy John surgery and recently agreed to extend his rehab assignment, but it's a moot point now that his shoulder's barking. Boone was vague and didn't disclose the extent of the issue, so it's unclear whether Trivino could still be an option in the postseason.

Cousins, whom the Yankees placed on the 15-day injured list earlier Sunday with a right pectoral strain, could resume mound work within the next week, Bryan Hoch of MLB.com reports.

The pec strain has brought Cousins' regular season to an end, but if he can return to elevated ground this week as hoped, he may still be an option for New York at some point in the postseason. Cousins ranks fifth on the team in holds with eight to go along with a 2.37 ERA, 1.05 WHIP and 53:20 K:BB over 38 innings in his first season in pinstripes.

The Yankees recalled Beeter from Triple-A Scranton/Wilkes-Barre on Sunday.

Beeter will come up to replace Jake Cousins (pectoral), who landed on the 15-day injured list. The right-handed Beeter was at one point feared lost for the season due to a shoulder injury, but he was able to return to action in the minors earlier this month. He allowed just one hit over four scoreless innings after rejoining Scranton/Wilkes-Barre.

The Yankees placed Cousins (pectoral) on the 15-day injured list Sunday, retroactive to Sept. 20.

There was initial optimism that Cousins would avoid the IL after he left Thursday's game with pectoral tightness, but his regular season is officially over after he was diagnosed with a right pec strain. Cousins has pitched well this season with a 2.37 ERA and 1.05 WHIP in 38 innings, and the Yankees are likely holding out hope that he can be an option in the postseason.
