The Tigers optioned Heuer to Triple-A Toledo on Wednesday, Evan Petzold of the Detroit Free Press reports.

Heuer has permitted three runs over 4.2 innings covering three relief outings between the Rangers and Tigers this season. He's being replaced on the roster by Sawyer Gipson-Long, who is back from the injured list.

The Tigers activate Gipson-Long (neck) from the 15-day injured list Wednesday, Evan Petzold of the Detroit Free Press reports.

Gipson-Long has been shelved since mid-July with a neck injury and had to be pulled off his initial rehab assignment due to continued stiffness. However, he's ready to go now after allowing two runs across 7.1 frames in two rehab appearances this month. Gipson-Long appears slated for a long-relief role for the time being.

The White Sox designated Shuster for assignment Wednesday.

The transaction frees up a spot on the 40-man roster for left-hander Martin Perez (elbow), who was activated from the 60-day injured list. Shuster has collected a 5.27 ERA over 62 career appearances (17 starts) at the big-league level.

The White Sox optioned Booser to Triple-A Charlotte on Wednesday.

Booser made a pair of scoreless appearances during his most recent stint in the big leagues, but he will nonetheless be dispatched back to the minors. The lefty reliever holds a 4.85 ERA and 29:14 K:BB over 26 innings this season.

While Abreu "would seem a logical choice" to take over as the Astros' closer following the injury to Josh Hader (shoulder), per Matt Kawahara of the Houston Chronicle, manager Joe Espada said Tuesday that he's "not naming (anyone) for the ninth."

Abreu has been phenomenal again this season, collecting a 1.67 ERA and 79:25 K:BB over 54 innings. The right-hander is the best bet to handle most of the save chances for the Astros while Hader is shelved, but Espada seems to be leaning toward more of a committee approach. With Hader unavailable, Bennett Sousa earned his fourth save of the season in Monday's win over the Red Sox. Abreu, Sousa, Steven Okert, Bryan King and Shawn Dubin could all be in the mix for saves for Houston while Hader is out.

Kahnle allowed two runs on two hits and two walks across 1.1 innings of relief in Tuesday's 9-6 loss to the White Sox. He struck out two.

Kahnle has allowed at least one run in five of his last six outings, and he has a 9.53 ERA during the rough stretch. Since the start of July, the veteran's ERA is 16.36. Before then, Kahnle was having a nice season with a 1.77 ERA, 0.79 WHIP and 31 strikeouts across his first 35.2 innings of 2025, but he's now sitting with a 5.21 ERA and 1.33 WHIP, and the righty has quickly fallen out of favor in the Detroit bullpen.

Munoz gave up a hit and a walk in a scoreless ninth inning Tuesday to record his 28th save of the season in a 1-0 win over the Orioles. He struck out one.

The right-hander is a perfect 7-for-7 in converting save chances since the All-Star break. Munoz hasn't been at his sharpest during that span, walking nine batters in 11 innings, but he's been scored on just once in 11 appearances thanks to 14 strikeouts. On the season, Munoz boasts a 1.34 ERA, 1.00 WHIP and 60:23 K:BB through 47 frames.

Hatch didn't factor into the decision Tuesday against the Yankees, allowing four runs on five hits and seven walks in 4.1 innings. He struck out two.

With several Twins starters on the injured list, Hatch was tasked with eating some innings as a long reliever but struggled mightily to find the plate. The 30-year-old right-hander tossed just 51 of his 99 pitches for strikes Tuesday, and the seven walks issued set a career-worst mark. Hatch has a 5.59 ERA, 1.76 WHIP and 6:8 K:BB over his first 9.2 innings. He'll carry minimal fantasy appeal in his next appearance, which is tentatively projected for this weekend in Detroit.

Mederos allowed three runs on three hits and three walks while striking out three over four innings in a no-decision versus the Dodgers on Tuesday.

Mederos gave up all three runs over the first two innings before settling in. He threw just 43 of 72 pitches for strikes, though he was pitching on short rest after taking the mound for Triple-A Salt Lake on Friday. Mederos has a 5.63 ERA, 1.50 WHIP and 7:7 K:BB across eight innings in the majors this year. This was his first big-league start, and it looks like the Angels may give him a longer look in the rotation. He is tentatively projected for a home start versus the Reds next week should he get another turn.

Leasure picked up the save in Tuesday's win over the Tigers, striking out the only batter he faced.

After Mike Vasil surrendered a three-run homer to Colt Keith in the ninth to trim Chicago's lead, Leasure was called on to face Spencer Torkelson and needed just five pitches to fan him and close out his fourth save of the season. The 26-year-old right-hander also has four blown saves this year and carries a 4.17 ERA, 1.39 WHIP and 56:23 K:BB across 45.1 innings.
