Zerpa (5-1) earned the win in Thursday's 6-4 victory over the Rangers. He allowed no hits or walks while striking out one over 1.2 innings.

The left-hander entered in relief of Michael Lorenzen with the bases loaded and one out in a tie game in the fifth inning Thursday and induced an inning-ending double play before tossing a perfect sixth frame. Zerpa has been on a roll, stringing together seven straight scoreless outings and posting a 2.43 ERA over 29.2 innings across his past 30 appearances.

Boyle (1-3) allowed six runs (five earned) on nine hits and three walks while striking out five over four innings to take the loss versus the Cardinals on Thursday.

The one bright spot was that he kept the ball in the yard for just the second time in his last six outings. Boyle has allowed at least six runs three times in that span, and he's also issued three or more walks in three of those starts. For the season, the 26-year-old is at a disappointing 5.40 ERA, 1.39 WHIP and 39:21 K:BB through 36.2 innings over 10 appearances (six starts). Boyle is tentatively projected to make his next start at Cleveland.

Silseth was optioned to Triple-A Salt Lake on Thursday.

Silseth was recalled Wednesday but will head back to the minors just one day later. He has yet to pitch in the majors in 2025, but he's maintained a 3.50 ERA and 1.33 WHIP with a 41:24 K:BB across 36 innings with Salt Lake.

Chapman pitched a perfect ninth inning with no strikeouts to earn the save in Thursday's 6-3 win over the Yankees.

Chapman threw just seven of 14 pitches for strikes, but he retired the heart of the Yankees' order on a popout and two groundouts. Dating back to July 26, Chapman has thrown 8.2 scoreless and hitless innings, posting a 9:2 K:BB over 11 appearances in that span. The 37-year-old closer is at 23 saves in 25 chances this year while maintaining a stellar 1.10 ERA, 0.71 WHIP and 69:14 K:BB, numbers in line with or better than what he posted in his prime.

Kimbrel signed with the Astros on Thursday, Jeff Passan of ESPN.com reports.

Kimbrel was granted his release by the Rangers on Thursday and inked his new deal the same day. He's made only one appearance in the majors this season, which came with Atlanta. The Astros are in need of bullpen help with Josh Hader (shoulder) sidelined, but Kimbrel is unlikely to factor into the saves picture.

The Guardians promoted Hartle to Double-A Akron on Thursday.

Hartle had played his entire 2025 season with High-A Lake Country prior to Thursday's promotion. He posted a 2.35 ERA with an 100:37 K:BB across 103.1 innings in 22 starts. The 22-year-old did not allow any earned runs in his last six starts since July 12, which included 28 strikeouts in 31 innings.

Estevez earned the save in Thursday's 6-4 win over the Rangers, striking out one in a perfect ninth inning.

Estevez has now converted eight straight save chances while allowing just four earned runs across his last 14 innings. The right-hander leads the majors with 33 saves this season while posting a 2.72 ERA with a 1.10 WHIP and 47 strikeouts across 56.1 innings.

Perkins (3-2) earned the win Thursday over the Twins, allowing two runs on three hits and four walks over five innings. He struck out two.

Perkins, who joined the A's rotation earlier this month, has won his last three starts while posting a 4.50 ERA with 14 strikeouts in that span (16 innings). Overall, the rookie right-hander sports a 4.19 ERA with a 1.16 WHIP and 37:18 K:BB across 38.2 innings this season. Perkins is currently lined up for a tough home matchup with the Tigers in his next outing.

The Yankees optioned Winans to Triple-A Scranton/Wilkes-Barre on Thursday.

Winans' stint with the Yankees lasted only one day without making an appearance. He's clearing out to make space on the roster for Paul Blackburn, who inked a major-league contract Thursday.

The Rangers activated Webb (back) from the 15-day injured list Thursday.

Webb has been sidelined all month with back spasms but is ready to roll after making three rehab appearances with Triple-A Round Rock. The 32-year-old has offered decent results in middle relief for the Rangers this season and will return to that role.
