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.

The Orioles recalled Hiraldo from Triple-A Norfolk on Saturday.

Hiraldo pitched 1.1 scoreless innings during his MLB debut May 27, but he's turned in a 5.75 ERA and 1.18 WHIP through 20.1 frames in Triple-A since then. He'll rejoin the Orioles' bullpen nonetheless to provide a fresh relief option, replacing Jeremiah Jackson on the active roster.

Lynch (elbow) will begin a rehab assignment with Double-A Northwest Arkansas on Saturday.

Nerve irritation in Lynch's left elbow landed him on the injured list July 6. Now that he has the green light to return to game action, the left-hander shouldn't require too many tune-up outings before being cleared to rejoin the Kansas City bullpen.

The Yankees reinstated De Los Santos (elbow) from the injured list Saturday.

De Los Santos landed on the injured list in mid-June due to elbow discomfort, but after two rehab outings in the minors, he'll now rejoin the Yankees' bullpen. The 27-year-old carries a 1.80 ERA and a 1.70 WHIP through 20 innings with New York this year and should take on a middle-relief role now that he's healthy.

The Guardians recalled Kent from Triple-A Columbus to serve as the team's 27th man for Saturday's doubleheader versus the Royals.

Kent is likely to stick around with the Guardians just for the day before heading back to Triple-A once the twin bill concludes. The 27-year-old righty has previously made four appearances out of the Cleveland bullpen this season, allowing five earned runs on eight hits and five walks while striking out eight over 7.1 innings.

Bowlan was called up from Triple-A Omaha and will serve as the Royals' 27th man for Saturday's doubleheader against Cleveland.

Bowlan owns a 4.64 ERA and 1.27 WHIP through 21.1 innings with the Royals this season. The 28-year-old will likely be demoted back to Triple-A following Saturday's twin bill.
