The Tigers released Heuer on Thursday.

The move clears space on the 40-man roster for the return of Paul Sewald (shoulder). Heuer has made three relief appearances at the big-league level this season between the Rangers and Tigers, yielding three runs with a 5:2 K:BB over 4.2 innings.

The Tigers designated Urquidy for assignment Thursday.

While the transaction for the time being is officially labeled as Urquidy being designated for assignment, the righty has agreed to be optioned to Triple-A Toledo and that is expected to happen Friday. Urquidy has allowed two runs over 2.1 innings since the Tigers reinstated him from the injured list earlier this week, and the club has decided it doesn't have a spot for him on the active roster right now.

The Tigers activated Sewald (shoulder) from the 60-day injured list Thursday.

Sewald was recovering from a right shoulder strain when the Tigers acquired him from the Guardians at the trade deadline, but he's made his way onto the active roster following five rehab appearances. The veteran reliever will likely be used in low-leverage spots initially but could find himself working in key situations if he looks sharp.

The Diamondbacks optioned Backhus to Triple-A Reno on Thursday.

Backhus has appeared in 32 games out of Arizona's bullpen this season, recording a 4.62 ERA, 1.42 WHIP and 22:8 K:BB across 25.1 innings. He picked up his second save of the season in last Sunday's win over the Twins.

The Diamondbacks selected Abner's contract from Triple-A Reno on Thursday.

The 23-year-old Abner opened 2025 in Single-A but has advanced through Arizona's minor-league system quickly and appears set to make his MLB debut in the coming days. The left-hander has a 3.07 ERA and 10.7 K/9 across 58.2 innings of relief in the minors this season. Abner was a sixth-round pick in the 2023 First-Year Player Draft.

The Angels will recall Aldegheri from Triple-A Salt Lake, Ari Alexander of KPRC 2 Houston reports.

The Angels have not announced any probable pitchers for their weekend series in Colorado, and Aldegheri could slot into the rotation one of those days. Aldegheri boasts a 2.52 ERA and 50:20 K:BB over 60.2 innings covering his last 10 starts between Double-A Rocket City and Salt Lake. The lefty has made two relief appearances for the Angels this season, yielding seven runs (five earned) across 4.1 frames.

The Royals recalled Avila from Triple-A Omaha on Thursday.

Avila was just sent down Wednesday but eligible to be recalled because he's replacing an injured player in Kyle Isbel (hamstring) on the roster. The rookie right-hander has allowed just one run with an 11:4 K:BB over 9.1 innings this season at the big-league level.

Cruz (shoulder) struck out two and gave up a hit and no walks over 1.1 innings in a rehab appearance for Triple-A Omaha on Wednesday.

Cruz has yet to allow a run in four rehab outings with Triple-A Omaha as he works back from right shoulder tendinitis. Before the injury, he posted a 3.61 ERA and 1.18 WHIP across 42.1 innings in 43 appearances out of Kansas City's bullpen. A return to the majors should come soon, giving the club a fresh relief option after a taxing series against Seattle.

Devenski was recalled from Triple-A Syracuse on Thursday.

The journeyman reliever carried a 5.92 ERA in 83.2 innings from 2022-24, but Devenski has a 2.30 ERA in 15.2 innings for the Mets this season, in part due to a 5.9% HR/FB and 80.9 LOB%. He should work in low-leverage situations.

Brazoban was recalled from Triple-A Syracuse on Thursday.

The 35-year-old righty has a 3.67 ERA, 1.30 WHIP and 51:27 K:BB in 56.1 innings across 47 appearances for the Mets this season. Brazoban should work in low-leverage situations during this stint in the majors.
