Baker (undisclosed) was pulled from Saturday's matchup versus Cincinnati due to an apparent injury, Marc Topkin of the Tampa Bay Times reports.

Baker entered in the seventh inning and struggled, allowing two runs on two walks and zero hits while striking out one batter. He flexed his lower right leg after his 22nd pitch and was subsequently visited by a trainer and pulled, though the Rays haven't announced a reason for his departure yet. Baker was acquired from the Orioles in a trade July 10 and picked up a hold in two of his first four appearances with Tampa Bay.

Kansas City traded Hoffmann to the Diamondbacks in exchange for Randal Grichuk on Saturday, Jon Heyman of the New York Post reports.

Hoffmann got into three major-league games with KC this season, posting a 3.86 ERA, 2.36 WHIP and 5:4 K:BB over 4.2 innings. He logged 15 starts over 29 appearances in the minors in 2024 but has been a full-time reliever this year, recording a 2.25 ERA, 1.12 WHIP and 55:10 K:BB over 40 frames spanning 32 appearances with Triple-A Omaha. Per Aaron Hughes of SI.com, Hoffmann will begin his Diamondbacks tenure with Triple-A Reno.

Robert allowed two runs on one hit and one walk in one inning of relief during Saturday's 9-4 win over the Yankees. He struck out one.

Saturday ended Robert's scoreless streak of eight outings, but it at least came with the Phillies holding a 9-1 lead in the seventh frame. The 30-year-old right-hander should continue to work in low-leverage situations in Philadelphia's bullpen, but he does own a respectable 2.35 ERA, 1.30 WHIP and 10:5 K:BB over his last 7.2 innings since being recalled from the minor leagues.

Espada agreed to a minor-league contract with the Orioles on Saturday, Rich Dubroff of BaltimoreBaseball.com reports.

Espada was cut loose by the Padres on Tuesday after posting a 3.38 ERA and 1.21 WHIP across 37.1 total innings between Double-A San Antonio and Triple-A El Paso. The 28-year-old has one career MLB appearance under his belt, but he'll likely need to show some improvement at the Triple-A level before he gets another chance in the majors.

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

Winans pitched three innings of three-run ball during Saturday's loss to the Phillies, and he'll promptly be sent back to the minors following the performance. The 29-year-old righty now carries an 8.68 ERA and 1.71 WHIP through 9.1 innings in the big leagues this season.

Rodriguez (forearm) will undergo Tommy John surgery Aug. 8, Marc Topkin of the Tampa Bay Times reports.

Rodriguez initially landed on the injured list in mid-June with a forearm strain. However, he suffered a setback in mid-July that caused him to move to the 60-day IL, and he'll now officially miss the remainder of the 2025 season. The timing of the 28-year-old's procedure also gives him little hope of pitching in 2026, leaving spring of 2027 as his likely return date.

The Reds optioned Mey to Triple-A Louisville on Saturday.

Mey was called up Friday after fellow reliever Scott Barlow was placed on the paternity list, but with Barlow back with the club Saturday, Mey is heading back to Louisville. The righty didn't get into Friday's contest but has a good chance of being back with the big club at some point later this season if a spot in the bullpen opens up.

Cincinnati activated Barlow from the paternity list Saturday.

Barlow was placed on the paternity list Friday but is back with the team after just one day. Luis Mey, who was brought up from Triple-A to take Barlow's bullpen spot Friday, has been optioned back to the minors in a corresponding move.

The Tigers designated Hartlieb for assignment Saturday.

After making two appearances with the Tigers and giving up two runs over two innings, Hartlieb will now be cast off the 40-man roster. Luke Jackson, who signed an MLB deal with Detroit on Saturday, will claim the open spot in the bullpen.

Jackson signed a one-year, major-league contract with the Tigers on Saturday, Evan Petzold of the Detroit Free Press reports.

Jackson was cut loose by the Rangers on Friday after posting a 4.11 ERA and 1.46 WHIP through 35 innings with the club. It didn't take very long for the 33-year-old righty to find his next gig, however, and he'll likely begin his tenure with Detroit as a middle reliever for the major-league team.
