Baker departed Saturday's contest against the Reds due to a right calf injury, Marc Topkin of the Tampa Bay Times reports.

The Rays aren't sure at this point if Baker is dealing with a cramp or a strain. If it's the former, Baker could be back in action shortly, but he could be out for longer if he's dealing with a strain. He's set for further evaluation Sunday.

Rodriguez will have right elbow surgery Aug. 8 to address a flexor tendon repair, and his UCL will be evaluated during the surgery to determine if any additional procedures are needed, Marc Topkin of the Tampa Bay Times reports.

An earlier report indicated Rodriguez will need Tommy John surgery, and while that remains a possibility, the full extent of the reliever's procedure won't be determined until the flexor tendon repair takes place. While Rodriguez is almost certain to miss the remainder of the 2025 campaign regardless, he could pitch in 2026 if Tommy John surgery is not needed. Assuming Rodriguez is indeed done for the current campaign, he'll finish with a 2.08 ERA, 1.05 WHIP and 25:6 K:BB over 30.1 innings spanning 31 appearances while notching 12 holds.

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.

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 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.

The Astros optioned Hernandez to Triple-A Sugar Land on Saturday.

After giving up two earned runs over 2.2 innings during Friday's contest, Hernandez will be sent down to Triple-A for the second time in the last four days. Luis Contreras was recalled from Sugar Land to fill the vacancy in the Astros' bullpen.

The Astros recalled Contreras from Triple-A Sugar Land on Saturday.

Since being moved to the minors in mid-April, Contreras has posted a 3.34 ERA and 1.37 WHIP alongside a 27:19 K:BB through 29.2 innings. He'll now get another shot as a middle reliever for the big-league squad, replacing Nick Hernandez.
