Keller appears to be the likeliest candidate to take over as the Cubs' closer after Daniel Palencia (shoulder) was placed on the 15-day injured list Monday, Bruce Levine of 670TheScore.com reports.

Palencia's availability for the remainder of the season is in jeopardy while he recovers from a right shoulder strain. Keller has been a revelation out of the Cubs bullpen this season and has yet to permit a run over 20 second-half appearances, yielding a total of just three hits over that stretch. If manager Craig Counsell prefers to take a committee approach at closer while Palencia is out, Andrew Kittredge and Caleb Thielbar could also be in the mix for saves along with Keller.

Fedde gathered a hold while giving up a double and retiring the other two batters he faced during a relief appearance in Saturday's 4-1 win over the Pirates.

Fedde made his second appearance as a member of the Brewers, this time working out of the bullpen after he had previously made a 4.1-inning start versus the Diamondbacks in his team debut Aug. 27. Since he tossed just 10 pitches Saturday, Fedde could be in consideration to make a spot start in Texas on Tuesday, when the Brewers will have a temporary opening in the rotation. However, Curt Hogg of the Milwaukee Journal Sentinel notes that Chad Patrick has joined the Brewers in Texas, so he could be formally recalled from Triple-A Nashville to draw the start over Fedde on Tuesday.

The Marlins optioned Roa to Triple-A Jacksonville on Monday.

Roa was with the big club for just a couple days, tossing two scoreless innings in his lone appearance. He's clearing out to make room on the active roster for Janson Junk (elbow), who is back from the 15-day injured list to start Monday's game versus the Nationals.

The Cubs placed Palencia on the 15-day injured list Monday due to a right shoulder strain, Maddie Lee of the Chicago Sun-Times reports.

The Chicago closer will hit the shelf after he experienced tightness in his shoulder during his relief appearance against the Nationals on Sunday, when he was dealt the loss and his third blown save of the season after failing to retire any of the five batters he faced while giving up four hits -- including two home runs -- and one walk. The Cubs haven't yet offered up a timeline for Palencia's return, but as a pitcher who's heavily reliant on high velocity and now coming back from an arm injury, he seems likely to be sidelined beyond the minimum 15 days. Manager Craig Counsell hasn't provided word on his plans for the ninth inning while Palencia is on the shelf, but Brad Keller, Andrew Kittredge and Caleb Thielbar have been pitching effectively in high-leverage spots of late and could be the Chicago relievers most likely to factor into the mix for saves over the next few weeks.

The Cardinals optioned Granillo to Triple-A Memphis on Monday.

Granillo has been an up-and-down performer during his big-league opportunities this season, collecting a 4.71 ERA and 18:7 K:BB over 21 innings. Nick Raquet was called up from Triple-A to take over Granillo's spot in the St. Louis bullpen.

The Cardinals selected Raquet's contract from Triple-A Memphis on Monday.

The 29-year-old southpaw reliever earned a promotion after posting a 1.68 ERA and 57:9 K:BB over 48.1 innings between Double-A Springfield and Memphis this season. Raquet will be making his major-league debut when/if he gets into a game.

The Phillies transferred Robert (forearm) from the 15-day injured list to the 60-day IL on Monday.

The transaction frees a spot on the 40-man roster for utility man Donovan Walton, who was called up from Triple-A Lehigh Valley in a corresponding move. Robert is now officially done for the season after sustaining a right forearm strain earlier this month.

The Brewers optioned Yoho to Triple-A Nashville on Monday.

Yoho struck out a pair in a scoreless frame during Sunday's win over the Pirates in what was his lone appearance during his most recent stint in the majors. Grant Anderson (ankle) was reinstated from the 15-day injured list to replace Yoho on the active roster.

The Brewers reinstated Anderson (ankle) from the 15-day injured list Monday.

Right-hander Craig Yoho was optioned to Triple-A Nashville to clear a spot on the active roster and in the bullpen for Anderson, who spent the minimum amount of time on the shelf while recovering from right ankle tendinitis. The 28-year-old compiled a 2.87 ERA, 1.21 WHIP and 66:27 K:BB in 62.2 innings with Milwaukee prior to landing on the IL and is likely to see most of his usage in middle relief.

Atlanta recalled Dunning from Triple-A Gwinnett on Monday.

Atlanta's bullpen saw heavy use over the previous two days, so Dunning will join the big club to provide a fresh relief arm. He's allowed 13 runs over 17.1 innings covering 10 appearances in the majors between Texas and Atlanta in 2025.
