DeSclafani is slated to start Wednesday's game against the Padres at Chase Field.

After working out of the bullpen in each of his previous three appearances, DeSclafani joined the Arizona rotation this past weekend as a replacement for Merrill Kelly, who was shipped to the Rangers ahead of the trade deadline. While making his first start for Arizona since July 6 on Friday in Sacramento, DeSclafani was dealt a loss while giving up four earned runs on five hits and three walks over 2.1 innings against the Athletics. Despite the rough showing, DeSclafani will get at least one more chance to solidify his spot in the Arizona rotation. Another poor outing, however, could prompt the Diamondbacks to go in a different direction with their No. 5 starter.

Iglesias gave up two hits and struck out one in a scoreless ninth inning Sunday to record his 14th save of the season in a win over the Reds.

Atlanta surprisingly didn't move Iglesias at the trade deadline despite an overheated market for late-inning relievers, and he's rewarded the team by collecting saves in back-to-back appearances since. The veteran right-hander has been scored upon only twice in his last 22 outings, posting a 2.18 ERA, 0.73 WHIP and 24:4 K:BB through 20.2 innings over that stretch while converting six of seven save chances.

The Nationals will recall Beeter from Triple-A Rochester, Spencer Nusbaum of The Washington Post reports.

Acquired from the Yankees in the Amed Rosario trade, Beeter has had an uneven 2025 season. He's been rocked for six runs with a 1:4 K:BB over 3.2 innings at the big-league level and held a 3.70 ERA and 40:20 K:BB over 24.1 frames during his time at Triple-A. The Nationals have a lot of uncertainty in their bullpen right now, so Beeter could work his way into a high-leverage role if he's able to throw enough strikes.

The Dodgers outrighted Penrod to Triple-A Oklahoma City on Sunday.

Penrod cleared waivers after being designated for assignment and will remain in the organization. The lefty has a 4.85 ERA with a 7:13 K:BB over 13 innings at Oklahoma City since being acquired via trade from the Red Sox in late June.

Gibaut (shoulder) tossed a perfect inning Sunday in his first rehab appearance with Triple-A Louisville.

Gibaut has been cleared for game action after being shelved for more than a month with a right shoulder impingement. He will could require at least one more rehab appearance before rejoining the Reds' bullpen.

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

Cincinnati and Atlanta were granted a 27th player on the active roster Sunday during the completion of the suspended Speedway Classic game, and Richardson filled that role for the Reds. The righty struck out three over two scoreless innings Sunday and will now rejoin Louisville's bullpen.

Shugart (knee) began a rehab assignment with Single-A Bradenton on Sunday, MLB.com reports.

Shugart has been sidelined since early July and resumed throwing a couple of weeks ago. He should be able to return relatively quickly and could immediately serve in a high-leverage role.

Stewart earned a hold against Tampa Bay on Sunday, allowing one hit in a scoreless inning of work.

Stewart began his career with the Dodgers but spent the past two-and-a-half campaigns in Minnesota. The Twins traded the veteran reliever back to Los Angeles on July 31, and Stewart made his 2025 debut with his new club Sunday. He handled the eighth inning in a close two-run game and worked around a two-out single by Junior Caminero to finish with a scoreless frame. Stewart's usage in his first game back with the Dodgers suggests he'll immediately be looked to for high-leverage work in a setup role.

Treinen didn't allow a run but yielded a hit and two walks while striking out two batters over two-thirds of an inning Sunday against Tampa Bay.

With the Dodgers up 3-0 entering the bottom of the ninth inning, manager Dave Roberts called upon Treinen to close things out. While the right-hander got two outs via punchout, he also put three runners on base and was pulled with two outs after walking Taylor Walls to bring the winning run to the plate. Ben Casparius entered and got Yandy Diaz to ground out to notch the save and shield Treinen from being charged with any runs, but this was Treinen's third shaky outing in a row since coming off the injured list last Sunday. Over those three appearances, the veteran reliever has surrendered five hits and four walks across just 1.2 frames, but he's managed to be charged with just one run. Los Angeles doesn't have a set closer at the moment with Tanner Scott (elbow) on the injured list, and Treinen is certainly among the candidates to get ninth-inning opportunities, as he did Sunday. However, his recent struggles may prompt Roberts to turn to another arm -- perhaps Casparius or lefty Alex Vesia -- the next time a save situation arises.

Nelson picked up the save Sunday against the Athletics, allowing one run on one hit while striking out one in the ninth inning.

Nelson was a surprise choice to close things out, but with Kevin Ginkel unavailable after throwing 20 pitches Saturday, the Diamondbacks turned to the 29-year-old lefty to finish off the win. His lone blemish was a solo shot off the bat of JJ Bleday, but he otherwise preserved the lead to notch the first save of his career in his 133rd MLB relief outing. Kendall Graveman, who handled the eighth inning against the heart of Oakland's lineup, may remain the top setup option behind Ginkel, but Nelson's usage hints at Arizona's willingness to mix and match in the late innings when needed.
