Sewald struggled in a save opportunity against the Nationals on Wednesday, allowing two runs on one hit and three walks in just one-third of an inning. He was pulled after throwing only nine of 24 pitches for strikes, and Ryan Thompson finished the inning. Diamondbacks manager Torey Lovullo attributed Sewald's issues to a delivery problem and did not confirm any changes to the closer role.

Exercise caution with Sewald and be ready to make changes based on his future performances and any official updates about his role. If more reliable closers are available on the waiver wire, you may want to consider dropping Sewald for a more stable option.

The Padres placed Kolek on the 15-day injured list Wednesday due to right forearm tendinitis.

The right-hander presumably suffered the injury during his appearance against the Dodgers on Tuesday, during which he allowed two walks over a scoreless inning. Kolek is without an official timeline for his return but will be eligible to be reinstated in mid-August.

The Padres optioned Gillaspie to Triple-A El Paso on Wednesday.

Gillaspie will lose his spot in the major-league bullpen as the Friars make room for Martin Perez, Tanner Scott and Bryan Hoeing -- all of whom were acquired Tuesday ahead of the trade deadline. After his promotion to San Diego on July 10, Gillaspie allowed three earned runs in 5.2 innings while striking out one batter and walking none.

The Padres designated Davis for assignment Wednesday.

The Padres needed to clear space for new acquisitions Martin Perez, Tanner Scott and Bryan Hoeing, so Davis will be jettisoned off both the active roster and the 40-man. The 31-year-old southpaw appeared in seven games for San Diego, allowing seven runs in seven innings while striking out six batters and walking five.

The Cubs reinstated Kilian (shoulder) from the 60-day injured list and optioned him to Triple-A Iowa on Wednesday, Meghan Montemurro of the Chicago Tribune reports.

Kilian had been on the shelf all season while recovering from a teres major strain of his right shoulder, but he's healthy again after completing an eight-appearance rehab assignment in the minors. The last five of those outings came at Iowa, with whom Kilian gave up seven runs (six earned) on eight hits and five walks while striking out three over eight innings. Though his results were generally poor, Kilian tossed three no-hit innings in his most recent appearance Sunday. Kilian had been working in relief during his rehab assignment, but since the Cubs didn't have a spot in the bullpen available for him upon his activation, he could get stretched back out for starting duty with Iowa.

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

Richardson got some work out of the bullpen in Tuesday's win over the Cubs, allowing two runs while retiring two batters. The right-hander will rejoin the rotation at Louisville.

Garrett (elbow) has been cleared to begin a rehab assignment with Triple-A Syracuse on Saturday after touching 97 mph in a live batting practice session Wednesday, Joe Pantorno of amNewYork Metro reports.

Garrett has been sidelined since mid-July with right elbow inflammation but looks to be healthy again. Given the short absence, Garrett might require just the one rehab appearance before rejoining the Mets' bullpen.

The Cardinals designated Bosiokovic for assignment Wednesday.

The transaction frees up a spot on the 40-man roster for right-hander Michael McGreevy, who was called up from Triple-A Memphis to start Wednesday's game against the Rangers. Bosiokovic was up with the big club briefly earlier this season but didn't make an appearance out of the bullpen.

The Cardinals recalled Loutos from Triple-A Memphis on Wednesday.

Loutos made two scoreless appearances earlier this season with the Cardinals and holds a 1.98 ERA and 43:16 K:BB over 36.1 frames at Memphis in 2024. He'll provide St. Louis with a fresh bullpen arm.

The Cardinals optioned Roycroft to Triple-A Memphis on Wednesday.

Roycroft wasn't going to be available for a day or two after throwing three innings and 50 pitches over the previous two days. Ryan Loutos was called up from Triple-A to take over Roycroft's spot in the bullpen.
