The Athletics placed Perkins on the 15-day injured list Friday with a strained right shoulder.

Perkins appears to have picked up the injury during Thursday's start against Minnesota, when he yielded two runs over five innings en route to his third win of the campaign. The 25-year-old has a 4.19 ERA in 38.2 innings with the A's this season. Joey Estes was recalled from Triple-A Las Vegas to fill Perkins' spot on the roster and presumably in the rotation.

The Athletics recalled Nunez from Triple-A Las Vegas on Friday.

Nunez will rejoin the A's active roster for the first time since being optioned Aug. 6. The 26-year-old will fill Ben Bowden's (lat) spot in the bullpen. A trade deadline acquisition from San Diego, Nunez has allowed two runs with a 10:2 K:BB in five innings with Las Vegas.

Sewald (shoulder) will throw a bullpen session Saturday, Evan Petzold of the Detroit Free Press reports.

It appears to be the first time Sewald has thrown off a mound since he was diagnosed with a moderate teres major strain in mid-July. The veteran reliever is eligible for activation from the 60-day injured list Sept. 10 and hopes to join the Tigers' bullpen for the stretch run.

Tinoco (forearm) will undergo surgery to repair his right forearm flexor and is expected to miss most, or all, of the 2026 season, Daniel Alvarez-Montes of ElExtraBase.com reports.

Tinoco has been on the shelf since June 6 with a strained right forearm and was shut down from throwing Aug. 12. He'll require a procedure to fix his right forearm flexor. Tinoco will have the surgery in early September and could miss the entirety of the 2026 campaign. The 30-year-old ends the 2025 season with a 5.12 ERA and 10:8 K:BB across 19.1 innings.

Loaisiga (elbow) will be examined by Dr. Keith Meister on Tuesday, Bryan Hoch of MLB.com reports.

The initial diagnosis is a right flexor strain, but Loaisiga will receive a second opinion from noted surgeon Dr. Meister in Texas. Whether Loaisiga needs surgery could be determined during that appointment. Loaisiga underwent an internal brace procedure on his right elbow in April of 2024.

The Rays optioned Boyle to Triple-A Durham on Friday.

Boyle had yielded 16 runs (15 earned) over his last three starts and did not last longer than four innings in any of those outings. He will look to sharpen things up back at Durham and hope to get another opportunity with the Rays later this season.

The Rays recalled Van Belle from Triple-A Durham on Friday.

Van Belle will receive his first look in the majors after being acquired from the Reds in the Zack Littell trade last month. The 29-year-old is taking the roster spot of Joe Boyle, who had been working out of the rotation for Tampa Bay and started Thursday versus St. Louis. Van Belle should be a candidate to fill that spot given his 3.17 ERA across 105 innings at Triple-A this year, but the Rays have yet to announce their updated pitching plans. Van Belle will likely be available out of the bullpen for the at least the next few days since the rotation opening won't come back up until next week in Cleveland.

The Astros optioned VanWey to Triple-A Sugar Land on Friday, Chandler Rome of The Athletic reports.

VanWey will cede his spot on the 26-man roster to Lance McCullers (finger), who is coming off the injured list to start Friday's game. The 26-year-old logged a 5.59 ERA and 1.86 WHIP in 9.2 innings with the Astros. He has a 4.34 ERA in 18.2 innings with Sugar Land in 2025.

The Astros placed Sousa on the 15-day injured list with left elbow inflammation Friday, Matt Kawahara of the Houston Chronicle reports.

It's not clear when Sousa's elbow began barking, but his last appearance came Tuesday in Detroit. He'll be eligible to return Sept. 4, but it's possible he'll need more time, given the nature of the injury. It's a blow to the Astros' bullpen, as Sousa holds a 2.84 ERA and 59:15 K:BB over 50.2 innings this season.

The Tigers optioned Lange to Triple-A Toledo on Friday, Cody Stavenhagen of The Athletic reports.

The right-hander was reinstated from the 60-day IL this week and delivered a scoreless frame in his first MLB appearance since May of 2024, but he won't retain his spot in Detroit's bullpen. Drew Sommers was called up Friday to fill Lange's place on the roster.
