Okert will serve as the Astros' opening pitcher in Tuesday's game versus the Marlins, Matt Kawahara of the Houston Chronicle reports.

Okert will cover the first inning or two before handing things off to AJ Blubaugh, who is expected to be the bulk reliever. The left-handed Okert has had a dynamite season out of the Astros' bullpen, registering a 2.90 ERA and 59:11 K:BB over 49.2 frames.

The Red Sox recalled Campbell from Triple-A Worcester on Tuesday.

Campbell has allowed two runs over two innings during his brief time in the majors this season, and he has collected a 4.17 ERA and 41:15 K:BB across 45.1 frames with Worcester. The righty will likely be used as a low-leverage reliever.

The Red Sox designated Alcala for assignment Tuesday.

Alcala has fanned 46 batters over 40.2 innings this season between the Twins and Red Sox, but he's also walked 23 while posting a 6.64 ERA. Not having minor-league options remaining will hurt him, but it would not be a surprise if another team takes a shot on the hard-throwing reliever.

Martin gave up six runs while failing to record an out in Monday's loss to the Phillies.

Martin notched a save last week against the Blue Jays, thrusting himself into the closer conversation as part of a bullpen that's lost Felix Bautista (shoulder) to injury and Gregory Soto, Seranthony Dominguez and Andrew Kittredge to trades. However, in his two appearances since that save, Martin has entered in the sixth inning both times. He managed to pitch around a couple hits in the first of those outings, but he was not so lucky Monday. The Orioles' bullpen remains unsettled, but it seems unlikely Martin will be entrusted with another save chance anytime soon.

The Orioles claimed Garcia off waivers from the Mets on Tuesday, Ari Alexander of KPRC 2 Houston reports.

Just within the last month, Garcia has bounced around from the Mets to the Yankees, back to the Mets and now to the Orioles via waivers. The righty reliever holds a 3.52 ERA and 18:4 K:BB over 15.1 major-league innings this season and will join an unsettled Baltimore bullpen.

Bednar earned a hold against Texas on Monday, striking out one batter in a perfect inning.

Bednar got the call in the eighth frame with the Yankees up by a run. He set the side down in order on 11 pitches (eight strikes). This was a much better outcome than in Bednar's team debut Aug. 1, when he allowed two runs on four hits over 1.2 innings. The veteran reliever entered in the seventh frame in that game, so it appears New York has him tabbed for a setup role. That said, Devin Williams blew his second straight save Monday and has yielded at least one run in three straight outings, so the team could shift to Bednar at closer if Williams continues to struggle.

The Yankees designated Brubaker for assignment Tuesday.

Brubaker returned to the majors this year after missing two seasons due to injury, posting a 3.38 ERA and 10:9 K:BB over 16 relief innings. Given his $1.82 million salary, it seems unlikely the right-hander will be claimed on waivers.

The Yankees recalled De Los Santos from Triple-A Scranton/Wilkes-Barre on Tuesday.

De Los Santos has collected a 1.78 ERA over 25.1 relief innings this season, though that's come with just a 20:12 K:BB. He will operate in middle relief.

The Yankees activated Leiter (leg) from the 15-day injured list Tuesday.

Leiter is recovered from the left fibular head stress fracture that sent him to the injured list in early July, and he's back with the Yankees after delivering a scoreless frame in his lone rehab appearance. The right-hander has a 4.46 ERA, 1.57 WHIP and 46:12 K:BB across 34.1 innings and should return to a middle-relief role for New York.

The Yankees are expected to designate Brubaker for assignment Tuesday, Robert Murray of FanSided.com reports.

Brubaker has managed a 3.38 ERA in 12 relief appearances for the Yankees, but it's come with an uninspiring 10:9 K:BB over 16 frames. The 31-year-old didn't pitch in the majors in 2023 or 2024 while recovering from multiple injuries, including Tommy John surgery. Brubaker will likely pass through waivers unclaimed.
