Megill (elbow) threw his second bullpen session Saturday since landing on the injured list and is expected to face hitters this week, MLB.com reports.

Megill is continuing to target a Sept. 16 return from the IL, which would represent a positive outcome after the Milwaukee closer was initially shelved Aug. 27 due to a Grade 1 right flexor strain. Before the Brewers clear him to rejoin the big-league bullpen, Megill will need to show during his throwing sessions that his command and velocity isn't affected by the injury, and he could require a tune-up outing in the minors prior to his activation. While Megill has been out of commission, Abner Uribe has collected three of the Brewers' five saves, with Jared Koenig and Aaron Ashby nabbing the other two.

Astros general manager Dana Brown said Sunday that Ort (elbow) could return from the 15-day injured list at some point during the postseason in a "best-case scenario," Chandler Rome of The Athletic reports.

Ort was placed on the IL on Friday due to right elbow inflammation, and Brown noted that the 33-year-old will be shut down from throwing for another 12-to-14 days before being re-evaluated prior to the final week of the regular season, per Matt Kawahara of the Houston Chronicle. Though Ort doesn't look like he has a chance at making it back from the IL for Astros' season-ending road trip, he shouldn't require an extensive ramp-up period once he resumes throwing and could be available for the playoffs. Ort has mostly been used in middle relief this season, logging a 4.89 ERA, 1.35 WHIP and 49:27 K:BB across 46 innings while nabbing two wins, one save and three holds in 49 appearances.

Astros general manager Dana Brown said Sunday that Sousa (elbow) could return from the 15-day injured list at some point during the postseason in a "best-case scenario," Chandler Rome of The Athletic reports.

Sousa hasn't resumed throwing since being placed on the injured list Aug. 22 due to a low-grade elbow flexor strain and doesn't appear to have a chance at returning before the end of the regular season. The 30-year-old will likely need to start throwing at some point in late September to put himself in consideration for a spot on the Astros' postseason roster. Before getting hurt, Sousa submitted a 2.84 ERA, 1.03 WHIP and 59:15 K:BB in 50.2 innings while collecting five wins, four saves and eight holds over his 44 appearances.

Atlanta designated Brebbia for assignment Monday.

He'll give up his spot on the 40-man roster and 28-man active roster to right-hander Alexis Diaz, whom Atlanta claimed off waivers from the Dodgers. After being called up from Triple-A Gwinnett on Aug. 29, Brebbia appeared in three games out of the Atlanta bullpen and surrendered five runs (four earned) on six hits and one walk while striking out six batters over 4.2 innings.

Atlanta optioned Munoz to Triple-A Gwinnett on Monday.

Munoz pitched each of the previous two days and was lit up for five runs over 1.1 frames in Sunday's loss to the Mariners. He will be replaced by a fresh bullpen arm in right-hander Connor Seabold, who was recalled from Gwinnett.

Atlanta recalled Seabold from Triple-A Gwinnett on Monday.

Seabold was claimed off waivers from the Rays in August and made one appearance for Atlanta, allowing two runs over 1.1 innings back on Aug. 19. He'll be back with the big club and will provide manager Brian Snitker with a fresh bullpen arm who's capable of covering multiple innings.

King (back) will throw a live batting practice session Monday, Derrick Goold of the St. Louis Post-Dispatch reports.

King will face fellow rehabbers Nolan Arenado (shoulder) and Brendan Donovan (groin), among others. The lefty reliever hasn't made an appearance in the majors since late July, first because of an oblique strain and later due to a mid-back strain. King will likely require at least one rehab appearance before being activated from the 15-day injured list.

Svanson struck out three over 1.2 scoreless innings to pick up a hold in Sunday's win over the Giants.

Svanson has quietly had a terrific rookie season in the Cardinals' bullpen and has been particularly dominant in the second half, collecting a 0.74 ERA, 0.86 WHIP and 30:9 K:BB over 24.1 innings. The 26-year-old is earning more and more high-leverage opportunities, having picked up four holds over his last seven appearances.

Topa was removed from his relief appearance in Sunday's 5-1 win over Kansas City in the ninth inning due to left knee discomfort, Matthew Leach of MLB.com reports. "I had the doctor look at it and he said that structurally, everything looks good," said Topa.

Topa was in line for a save chance but exited with two outs in the ninth with the Twins holding a four-run lead, paving the way for Genesis Cabrera to record the game's final out. While Topa said that his knee is fine, he may need a few days off for any soreness to subside. Topa previously missed most of the 2024 season due to patellar tendinitis and a small tear in the patellar tendon in his left knee.

Armstrong picked up the save Sunday against Houston, striking out one over 1.1 perfect innings.

Armstrong has now pitched more than one inning in three of his last four saves. The 34-year-old hasn't yielded a hit or a walk in three consecutive outings, a streak that spans 3.2 innings. He owns a 2.40 ERA, seven saves and a 64:18 K:BB across 63.2 innings this season.
