The Tigers reinstated Horn from the paternity list Thursday, Chris McCosky of The Detroit News reports.

Horn will reclaim a middle-relief role in the Tigers' bullpen after spending two days away from the team for the birth of his child. Drew Sommers was sent back to Triple-A Toledo in a corresponding move.

The Mets recalled Brazoban from Triple-A Syracuse on Thursday.

Brazoban has put up a 3.91 ERA and 1.32 WHIP across 53 innings in the big leagues this season. He'll rejoin the Mets' bullpen to provide the team with an additional fresh arm, replacing Justin Hagenman, and is likely to work primarily in middle relief.

The Mets optioned Hagenman to Triple-A Syracuse on Thursday.

Hagenman did his best to save the Mets' bullpen by throwing 75 pitches during a three-inning relief appearance Tuesday in Philadelphia. Unfortunately for him, he'll now have to be replaced by a fresh relief arm.

The Marlins designated Martinez for assignment Thursday.

Martinez has made six appearances since joining the active roster Aug. 27, across which he coughed up four earned runs over 6.2 innings. He'll now lose his place on the MLB and 40-man rosters to make room for Ryan Weathers' (lat) return from the 60-day IL.

The Reds optioned Zulueta to Triple-A Louisville on Thursday.

With Graham Ashcraft (forearm) and Chase Burns (elbow) both returning from the injured list Thursday, the Reds will move Zulueta and Lyon Richardson to Triple-A in order to create roster space. Zulueta gave up two runs over two innings during his latest stint with Cincinnati, elevating his big-league ERA to 6.14 through 7.1 frames.

The Reds activated Ashcraft (forearm) from the 15-day injured list Thursday.

Ashcraft was shelved for the past two weeks with a right forearm strain, but he'll skip a rehab assignment and rejoin the Reds' bullpen for their weekend series against the Athletics. The right-hander has posted a 3.72 ERA and 56:24 K:BB over 58 innings in 2025 in his first season as a full-time reliever.

The Reds optioned Richardson to Triple-A Louisville on Thursday.

Richardson will be sent down to the minors alongside Yosver Zulueta in order to make room on the active roster for Graham Ashcraft (forearm) and Chase Burns (elbow), both of whom returned from the injured list Thursday. Richardson, 25, surrendered three earned runs in one inning during his lone appearance since being promoted Sept. 3 and now carries a 4.54 ERA and 1.54 WHIP through 37.2 MLB frames.

The Rays recalled Gerber from Triple-A Durham on Thursday.

Gerber was added to the 40-man roster in July, but this will be his first stint in the big leagues since 2020. The 28-year-old has collected a 6.23 ERA with Durham this season, but that has come with an impressive 54:15 K:BB over 43.1 innings.

The Rays recalled Orze from Triple-A Durham on Thursday.

Orze has spent the last two months in the minors despite holding a 2.72 ERA and 38:15 K:BB over 39.2 innings for the Rays this season. He'll give manager Kevin Cash a fresh relief arm after a bullpen game Wednesday.

The Rays optioned Rock to Triple-A Durham on Thursday.

Rock covered 2.2 scoreless innings Wednesday against the White Sox, and his reward is a trip back to the minors. The Rays have summoned Eric Orze and Joey Gerber to supplement their bullpen.
