Sewald (shoulder) began a rehab assignment with High-A West Michigan on Thursday, Emily Waldon of Baseball America reports.

Sewald landed on the injured list in mid-July and has been throwing for around a month. Due to his long layoff, he may need to make several rehab appearances before being activated.

Jax will serve as the Rays' opening pitcher in Friday's game against the Guardians, Marc Topkin of the Tampa Bay Times reports.

Jax has worked primarily in high-leverage spots all season, and that has continued since he joined the Rays at the trade deadline. However, he's struggled to a 7.20 ERA and 1.80 WHIP across 10 innings with Tampa Bay, so working as an opener could prove to be a bit of a reset for the right-hander. Jax will likely only work an inning or two before giving way to Ian Seymour, who is expected to work in bulk relief.

Estevez allowed a hit and struck out two in a scoreless inning to earn the save in Thursday's 4-3 win over the Angels.

Estevez has allowed just two hits while racking up nine strikeouts during his eight-inning scoreless streak. He's earned seven saves in that span and continues to lead the majors with 37 saves on the year. He's added a 2.54 ERA, 1.06 WHIP and 52:20 K:BB through 60.1 innings this season and is unlikely to be challenged for the closing role during September.

Martin cleared waivers Thursday and was sent outright to Triple-A Norfolk, Jake Rill of MLB.com reports.

Martin will officially stick in the Orioles organization after being designated for assignment Tuesday. He'll provide the club with organizational bullpen depth at Norfolk, but after putting up a 5.29 ERA and 1.40 WHIP through 32.1 innings in the minors, he's unlikely to get another opportunity with the O's this year.

Headrick (forearm) will begin a rehab assignment Thursday at Triple-A Scranton/Wilkes-Barre.

A bruised forearm has kept Headrick on the injured list since mid-August, but he's now been cleared to begin playing in minor-league games in preparation for his return to the Bronx. The 27-year-old sports a 3.13 ERA and 1.04 WHIP through 23 innings with the Yankees this year and should claim a middle-relief role in their bullpen once healthy.

The Guardians recalled Kent from Triple-A Columbus on Thursday, Tim Stebbins of MLB.com reports.

With Nic Enright (elbow) landing on the injured list, Kent will turn around and rejoin the big-league squad after being demoted to Columbus on Wednesday. The 27-year-old has given up five earned runs through 9.2 innings in the majors this year and will presumably be limited to low-leverage opportunities while with the Guardians.

The Guardians placed Enright on the 15-day injured list Thursday with right elbow/forearm inflammation, Tim Stebbins of MLB.com reports.

Enright pitched a scoreless two-thirds of an inning during his latest appearance Tuesday, but he appears to have come away from the outing with an elbow issue. The Guardians will now keep him on the shelf for at least two weeks and bring up Zak Kent from Triple-A Columbus to round out their bullpen.

The Rangers activated Winn (hand) from the 15-day injured list Thursday.

Winn missed the last couple weeks with nerve irritation in his right hand, but he's ready to go following a brief rehab assignment. The right-hander has authored a 1.45 ERA and 26:15 K:BB over 31 innings covering 25 relief appearances for the Rangers in 2025.

The Rangers placed Coulombe on the 15-day injured list Thursday with left shoulder fatigue, retroactive to Monday.

Coulombe hasn't made an appearance out of the bullpen since giving up three earned runs in just one-third of an inning Aug. 26, and his shoulder injury provides some clarity to the situation. He'll remain on the sidelines until at least Sept. 16, and the Rangers will return Cole Winn (hand) from the IL to claim the open bullpen spot.

The White Sox designated Wilson for assignment Thursday.

Wilson's time with the White Sox will come to an end after just five days, during which he threw two shutout innings in his lone appearance Tuesday against Minnesota. The 27-year-old cleared waivers and remained with the organization when he was DFA'd in June, and there's a strong chance he does the same this time around.
