The Reds transferred Gibaut (shoulder) from the 15-day injured list to the 60-day injured list Friday.

The transaction frees up a spot on the 40-man roster for the addition of Zach Maxwell. Gibaut is set to miss the remainder of the season following arthroscopic surgery on his right shoulder.

The Reds selected Maxwell's contract from Triple-A Louisville on Friday.

Maxwell will make his MLB debut when he gets into a game. The 24-year-old reliever has a 4.17 ERA and a 1.50 WHIP with a 59:32 K:BB across 49.2 innings for Louisville in 2025. Ian Gibaut (shoulder) was transferred to the 60-day injured list in a corresponding move.

Cruz (shoulder) is throwing from about 75 feet and is in the beginning stages of his throwing progression, MLB.com reports.

Cruz was placed on the injured list Aug. 3 with right shoulder tendinitis and, per manager Matt Quatraro, is still in the early stages of his rehab. While no firm return date has been set, the slow pace of his recovery suggests the 26-year-old is more likely to return sometime in September than by the end of August.

Cruz (oblique) is slated to make a four-out minor-league rehab appearance Friday, and if that goes well, he could be activated from the injured list as soon as Monday, per MLB.com.

Cruz landed on the injured list in late June due to a left oblique strain. The veteran reliever kicked off a minor-league rehab stint Aug. 14 and has appeared in three games so far (two with Triple-A Scranton/Wilkes-Barre and one with Double-A Somerset), allowing four runs on five hits with a 4:1 K:BB over 2.1 innings. Though those numbers are poor, Cruz's most recent outing was strong -- he struck out the side and gave up only one hit over one scoreless frame Tuesday. Once activated off the IL, Cruz should be a candidate for high-leverage work, though he may be eased back given his lengthy absence. He also may be lower on the depth chart than when he last pitched, as New York added David Bednar and Camilo Doval to the bullpen at the trade deadline.

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.

Romero allowed a hit and struck out three over two scoreless innings to earn the save in Thursday's 7-4 win over the Rays.

Romero was brought in for the eighth inning and threw 15 pitches in that frame. He stayed in for the ninth and added 11 more pitches to secure his fourth save of the season. It's encouraging usage for Romero, who had two losses, one blown save and two holds over hos previous four appearances, which made it look like his time as closer was over just weeks after it started. The lefty reliever has a 2.31 ERA, 1.26 WHIP and 45:21 K:BB while adding 18 holds over 46.2 innings this season. Riley O'Brien has had a fairly stable August compared to Romero, which has pushed the Cardinals' late-inning situation into more of a committee approach.

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.

Ferrer earned the save in Thursday's 9-3 win over the Mets, allowing one hit and no walks in 1.1 scoreless innings. He struck out three.

Ferrer entered the game with the Nationals nursing a 5-3 lead in the eighth inning, but Washington scored four more runs in the bottom half of the frame to give him a big cushion to work with while recording the final three outs. The 25-year-old southpaw has emerged as the clear favorite for saves following the Kyle Finnegan trade, having now converted each of his four save chances in August. Over his last 18.2 innings, Ferrer sports a 1.93 ERA, 1.18 WHIP and 18:2 K:BB.
