The Royals recalled Avila from Triple-A Omaha on Thursday.

Avila was just sent down Wednesday but eligible to be recalled because he's replacing an injured player in Kyle Isbel (hamstring) on the roster. The rookie right-hander has allowed just one run with an 11:4 K:BB over 9.1 innings this season at the big-league level.

Cruz (shoulder) struck out two and gave up a hit and no walks over 1.1 innings in a rehab appearance for Triple-A Omaha on Wednesday.

Cruz has yet to allow a run in four rehab outings with Triple-A Omaha as he works back from right shoulder tendinitis. Before the injury, he posted a 3.61 ERA and 1.18 WHIP across 42.1 innings in 43 appearances out of Kansas City's bullpen. A return to the majors should come soon, giving the club a fresh relief option after a taxing series against Seattle.

King earned a save against the Rangers on Wednesday by pitching 1.1 perfect innings. He did not record any strikeouts

King entered with two outs in the eighth inning, inheriting two runners on base. He got Dylan Moore to fly out, then retired all three batters he faced in the ninth to close out the contest. The save was King's second of the campaign and his first since July 22. Bryan Abreu has taken over closer duties for Houston with Josh Hader (shoulder) out of action, but Abreu was held out Wednesday after pitching each of the previous two days. It makes sense that the Astros turned to King late in the game, as he's now given up just one run while posting a 17:2 K:BB over his past 17 innings spanning 16 appearances.

Fairbanks earned the save in Wednesday's 2-1 win over the Blue Jays, striking out one in a perfect ninth inning.

Called upon to protect a one-run lead, the right-hander locked down his 27th save of the season with ease, continuing his bounce-back form after a rocky stretch in which he allowed six earned runs over seven appearances. Since then, Fairbanks has gone four straight outings without allowing a hit, converting three saves in that span. The 31-year-old now sports a 2.98 ERA, 1.10 WHIP and 58:18 K:BB across 57.1 innings this season.

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.
