Seymour (4-2) earned the win Wednesday against the Blue Jays, allowing one unearned run on four hits and one walk while striking out three over seven innings.

The left-hander was sharp throughout, with Toronto's lone run coming in the fourth inning after a defensive miscue on a potential double-play ball extended the frame. Seymour has been hurt by poor defense lately, as he's surrendered 13 runs over his last four starts despite only four being earned. He's been excellent during that stretch, pitching to a 1.69 ERA with a 21:6 K:BB across 21.1 innings. Wednesday's outing also marked the longest start of Seymour's short career, surpassing his previous high of 5.1 innings from his previous start. The 26-year-old is slated to face Baltimore in his next outing.

Estevez (back) picked up the save Wednesday against the Mariners, allowing one run on three hits with no strikeouts or walks in the ninth inning.

After leaving Sunday's win over Philadelphia due to mild back tightness, Estevez returned to action Wednesday but was shaky in collecting his MLB-leading 40th save. The earned run was his first allowed since Aug. 13 versus Washington, and the three hits given up were his most since July 3 in Seattle. Estevez has still produced a 2.53 ERA, 1.08 WHIP and 52:22 K:BB over 64 innings, and the veteran right-hander appears to be locked in as the Royals' closer to close out his excellent campaign.

Martin (hand) hit a batter but allowed no other baserunners during an inning of relief in Tuesday's 6-5 loss to the Astros.

Martin experienced some tingling in his right hand during his previous relief appearance in Saturday's 3-2 win over the Mets, but a couple days off was all he needed for the issue to be resolved. The veteran righty made quick work of the Astros in the ninth inning Tuesday, needing just seven pitches to record three outs.

Akin earned the save in Wednesday's 3-1 win over the White Sox, allowing one hit in a scoreless ninth inning.

Akin is up to seven saves on the season, including three in the last seven days, as he continues to work as Baltimore's primary closer. Overall, Akin sports a 3.15 ERA with a 1.37 WHIP and 56 strikeouts through 60 innings this year.

Finnegan (groin) will begin a rehab assignment with Triple-A Toledo on Thursday, Chris McCosky of The Detroit News reports.

Finnegan has missed most of September with a right adductor strain but has been cleared to test things out in a game setting. Given his brief absence, it could be the only rehab appearance Finnegan needs before returning to the Tigers' active roster. He's made 12 scoreless appearances and recorded four saves since being acquired by Detroit at the trade deadline.

Red Sox manager Alex Cora said that Harrison will start Saturday's game against the Rays in Tampa, Jen McCaffrey of The Athletic reports.

Harrison will move into the rotation as a replacement for rookie lefty Payton Tolle, whom Cora said would be used in the bullpen for the remainder of the season. After getting called up from Triple-A Worcester last week, Harrison made his Red Sox debut out of the bullpen Sept. 10 in Sacramento, striking out two over three scoreless innings. Though he had been serving in a starting role for Worcester, Harrison hadn't covered five frames in an outing since Aug. 19, so the Red Sox may not be counting on the lefty working deep into his start Saturday.

The Royals optioned Avila to Triple-A Omaha on Wednesday.

He's being sent down in order to clear a spot on the active roster for the return of Cole Ragans (shoulder) from the 60-day injured list. Avila has allowed just one run with an 11:4 K:BB over 9.1 frames with the big club, but having minor-league options remaining worked against him.

White Sox general manager Chris Getz said Wednesday that he expects Vasil to remain in the bullpen next season, Scott Merkin of MLB.com reports.

Vasil was a starter throughout his time in the minors with the Mets before the White Sox plucked him in the Rule 5 Draft last offseason, so he'd be capable of getting stretched out. However, Getz and the White Sox like the versatility Vasil provides in the bullpen, with his ability to eat multiple innings and appear in high-leverage situations, depending on what is needed. Vasil has posted a 2.45 ERA, 1.22 WHIP and 77:47 K:BB over 95.2 innings, picking up five wins, four saves and two holds along the way.

The Rays optioned Gerber to Triple-A Durham on Wednesday, Ryan Bass of FanDuel Sports Network Sun reports.

Gerber pitched well in two relief outings for the Rays, allowing one run with a 4:0 K:BB across 4.1 frames. He's being replaced by a fresh bullpen arm, as the Rays have summoned Cole Wilcox from Triple-A Durham in a corresponding move.

Smith (7-5) blew the save but picked up the win Tuesday, striking out two and giving up a solo home run in the ninth inning of a 7-5 extra-inning victory over the Tigers.

Called in to protect a 3-2 lead, Smith instead served up a game-tying homer to Kerry Carpenter, only for the Cleveland offense to erupt for four runs in the top of the 10th. It's the right-hander's first blown save since Aug. 22, ending a streak of eight straight successful conversions, and since taking over the closer role in late July he's posted a 3.38 ERA, 0.88 WHIP and eye-popping 33:2 K:BB in 24 innings while securing 12 of 16 save chances.
