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 Mets are expected to call up McLean from Triple-A Syracuse to start Saturday's game against the Mariners, Andy Martino of SNY.tv reports.

With manager Carlos Mendoza permanently moving Frankie Montas to the bullpen, the Mets will need to break in a new fifth starter this weekend. Though veteran righty Paul Blackburn (shoulder) has been building up a starter during his rehab assignment and looks ready to come off the 15-day injured list, the Mets instead appear inclined to give the 24-year-old McLean his first look in the big leagues. The right-hander has made 21 appearances (18 starts) between Double-A Binghamton and Triple-A this season, registering a 2.45 ERA and 1.13 WHIP while racking up 127 punchouts over 113.2 innings. The Mets could get Tylor Megill (elbow) back from the injured list by the end of the month to challenge him for a rotation spot, but if McLean impresses in his initial taste of the majors, he could end up holding down a starting role for the rest of the season.

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.

The Dodgers recalled Henriquez from Triple-A Oklahoma City on Tuesday.

Henriquez tossed 1.1 scoreless innings in Tuesday's extra-inning loss to the Angels, marking his fourth scoreless relief outing with the big club this season. The hard-throwing righty will occupy a middle-relief role with the Dodgers.

Morillo picked up the save Tuesday against the Rangers, throwing a perfect ninth inning with no strikeouts.

The Diamondbacks are still searching for a closer to replace Kevin Ginkel (shoulder), who was shut down for the season in early August. Morillo, a 26-year-old rookie who's bounced between the big leagues and Triple-A during 2025, appears to be in the running for the position. While he has a 4.76 ERA and 28:16 K:BB in 28.1 innings with Arizona this season, Tuesday's performance could have earned him some trust with manager Torey Lovullo. Morillo posted a 3.00 ERA in 15 innings with Triple-A Reno this year.

DeSclafani was removed from Tuesday's start after three innings due to soreness in his right thumb, MLB.com reports. He allowed two runs on three hits and two walks while striking out three in a no-decision against the Rangers.

DeSclafani attempted to pitch through the soreness but was yanked after three innings and 52 pitches. The right-hander said following the game that he wasn't sure if a stint on the injured list would be needed. The Diamondbacks are expected to evaluate DeSclafani on Wednesday.
