The Athletics optioned Maldonado to Triple-A Las Vegas on Monday.

The transaction clears a spot on the 26-man active roster for J.T. Ginn (elbow), who will return from the injured list to start Monday's game against the Angels. Maldonado was called up Friday and allowed two runs on three hits while striking out two during his lone one-inning appearance out of the Athletics bullpen. He'll return to Triple-A, where he's posted a 0.73 ERA, 0.66 WHIP and 17:2 K:BB across 12.1 innings.

The Royals activated Clarke from the paternity list Monday.

Clarke missed the weekend series versus the Cardinals while welcoming a new addition to the family, but he's back for the start of a three-game set in San Francisco. The righty has tossed 5.1 scoreless frames with the Royals this season.

Guenther will serve as the Tigers' opening pitcher for Monday's game against the Cardinals, Chris McCosky of The Detroit News reports.

Guenther will draw his first MLB start Monday, though he hasn't covered more than two innings in any of his nine appearances between the big club and the minors this season and is unlikely to work deep into the contest. Keider Montero is slated to cover the bulk of the innings out of the bullpen once Guenther exits the game.

Jackson (hand) issued a walk and struck out a batter in a scoreless inning during Sunday's 4-3 loss to the Astros.

Jackson battled a swollen hand throughout the week after being hit by a comebacker May 12 against the Rockies, but he returned to the mound Sunday in a non-save situation. The right-hander didn't appear to have any lingering issues as he threw 10 of 15 pitches for strikes, and his average fastball velocity of 93.6 mph was only marginally lower than his season average. Shawn Armstrong picked up a pair of saves in his absence, but Jackson should reclaim primary closing duties now that he's healthy.

Neris suffered a right finger blister during his appearance against the Dodgers on Saturday and was held out of Sunday's series finale due to the issue, per MLB.com.

The blister may help explain Neris' rough outing Saturday -- he gave up three runs on two walks and a hit while uncorking a wild pitch without retiring any batters. This doesn't appear to be a serious injury for the veteran reliever, but the Angels probably will opt to hold him out until the blister is healed enough to no longer affect his throwing. Neris joined the Angels on a minor-league deal in mid-April and had tossed five straight scoreless outings before his blow-up Saturday.

Vest tossed a scoreless inning with one strikeout to record the save in Sunday's 3-2 win over the Blue Jays.

Despite not allowing a hit or a walk, Vest needed 24 pitches to retire three batters, but he still managed to earn his fifth save of the year in seven chances. The veteran righty is strengthening his hold on the top closer role in Detroit, as he now has a sparkling 1.66 ERA, 1.02 WHIP and 25 strikeouts across 21.2 innings. Tommy Kahnle, who has five saves of his own this season, worked a clean eighth inning Sunday and will continue to be in the mix for saves moving forward.

Yarbrough is scheduled to start Wednesday's game against the Rangers, Gary Phillips of the New York Daily News reports.

The left-hander last pitched May 11 in Sacramento, so he'll be taking the mound Tuesday with a bit of extra rest. Yarbrough allowed two runs over five frames in that outing while picking up his first win of the season, and he's been a quality swingman for the Yankees early on in 2025 with a 3.70 ERA, 1.27 WHIP and 20:10 K:BB across 24.1 innings.

Estevez picked up the save in Sunday's 2-1 victory over St. Louis, allowing a hit in a scoreless inning with one strikeout.

The Kansas City closer worked around a Brendan Donovan double and efficiently secured the win on 12 pitches, eight of which were strikes. Estevez has been a reliable reliever over his last 10 appearances, conceding just one run while pitching to an 8:1 K:BB across 9.2 innings. The 32-year-old has gone a perfect 8-for-8 on save opportunities during that span as he maintains his firm grip on the closer job over Lucas Erceg.

Hader earned the save in Sunday's 4-3 win over the Rangers, striking out two in a perfect ninth inning.

Hader faced the bottom of the Rangers' lineup and retired them in order to remain a perfect 11-for-11 in save chances this season. The southpaw has allowed runs in just two of his past 10 appearances, both coming in non-save situations. On the year, he owns a 1.80 ERA, 0.85 WHIP and 29:5 K:BB across 20 innings.

Martin was removed from Sunday's game against the Astros due to right shoulder discomfort, Kennedi Landry of MLB.com reports.

The right-hander departed after throwing just one pitch Sunday, which is the same thing that happened when elbow tightness forced him from Tuesday's game versus Colorado. It could be encouraging that Martin didn't aggravate the same injury, but the fact a 38-year-old is dealing with different arm issues in such a short window is worrying in its own right.
