The Astros placed Hader on the 15-day injured list Tuesday, retroactive to Aug. 11, due to a left shoulder strain.

The All-Star closer was unavailable for the save Monday against the Red Sox due to left shoulder discomfort, and he's now been diagnosed with a strain. Hader will be eligible to be reinstated Aug. 26, though he's without an official timeline for his return since a recovery timetable has yet to be announced. Enyel De Los Santos and Bennett Sousa combined to handle the ninth inning Monday, but setup man Bryan Abreu is the likely favorite to fill in as Houston's closer.

Interim manager Tony Mansolino announced Tuesday that Bautista (shoulder) will miss the rest of the 2025 season, Matt Weyrich of The Baltimore Sun reports.

The right-hander was diagnosed with swelling in his shoulder after landing on the injured list in late July, which is significant enough to sideline him for the rest of the campaign. Bautista is without an official timeline for his return, but that could come into focus once he's further evaluated later this week. Keegan Akin has received the first look as Baltimore's new closer, going 2-for-3 in save chances since Bautista went down.

Robert (finger) will begin a rehab assignment with Triple-A Lehigh Valley on Tuesday.

Robert was placed on the 15-day IL with a blister on his right middle finger, which he suffered July 30. Robert has pitched in 12 games out of the bullpen for Philly this season, logging a 5.79 ERA, 1.82 WHIP and 12:8 K:BB across 9.1 innings of work.

The Mariners claimed Gonzalez off waivers and optioned him to Triple-A Tacoma on Tuesday.

The right-hander was designated for assignment by Atlanta over the weekend but will retain a place on a 40-man roster with Seattle. Prior to the transaction, Gonzalez had spent the full season at Triple-A Gwinnett and had a 3.95 ERA, 1.37 WHIP and 39:19 K:BB across 41 innings.

The Marlins activated Bender from the paternity list Tuesday.

Bender missed Miami's weekend set against Atlanta but is back with the team ahead of a three-game series against the Guardians. The 30-year-old right-hander has a 2.30 ERA, 1.09 WHIP and 38:19 K:BB across 47 innings pitched this season. Bender has recorded three saves.

The Red Sox released Stock on Tuesday, Tim Healey of The Boston Globe reports.

Stock was designated for assignment June 9, and he's been playing for Triple-A Worcester since. However, he'll hit the open market after Tuesday's move. The 25-year-old has thrown 85 innings at Triple-A this season, posting a 3.92 ERA and a 96:36 K:BB.

King (oblique) will throw a full-effort bullpen session Wednesday and, if it goes well, will begin a rehab assignment this weekend, Derrick Goold of the St. Louis Post-Dispatch reports.

King has thrown a pair of bullpen sessions since going on the 15-day injured list in late July with a left oblique strain, but Wednesday's session will be his first at full effort. The lefty reliever hasn't missed much time, so he could be ready to rejoin the active roster next week after a brief rehab assignment.

Gibaut (shoulder) has returned to Cincinnati, where he is undergoing tests after being pulled from a rehab assignment, MLB.com reports.

Gibaut was roughed up in a rehab outing for Triple-A Louisville last week and had the assignment paused when his arm didn't recover well. It's unclear if it was the shoulder or another part of the arm that is the source of the current problem.

Fairbanks earned a save against the Athletics on Monday, allowing one hit and striking out one batter over one scoreless inning.

Fairbanks had a relatively easy path to a save, as he entered with a three-run lead in the ninth frame. The right-hander gave up a leadoff double but then settled in and retired the next three batters. Fairbanks has now reached 20 saves in each of his past three campaigns, and he has an excellent shot at exceeding his career-best mark of 25 regular-season saves, which he recorded in 2023.

Sousa picked up the save in Monday's 7-6 win over the Red Sox. He allowed no hits or walks while striking out the lone batter he faced.

Sousa needed just four pitches to secure his fourth save of the season Monday, taking over for Enyel De Los Santos with one out left in the ninth inning and striking out Roman Anthony to end the game. The left-handed reliever isn't expected to handle closing duties on a regular basis but stepped in with Josh Hader temporarily unavailable due to left shoulder discomfort.
