White (hip) began a rehab assignment with Triple-A Charlotte on Thursday.

White has been on the injured list since Aug. 19, one day after making his third appearance in the majors this season. It's unclear if he'll stick in the White Sox's bullpen upon his activation.

Abreu notched the save Thursday against Colorado, allowing one hit and no walks in a scoreless ninth inning. He struck out two.

Abreu secured his fourth save of the year and extended his scoreless streak to 13 innings. With Josh Hader (shoulder) likely to be out until the playoffs, Abreu has established a fairly strong grip on Houston's closer gig. The veteran right-hander has a 1.47 ERA, 0.98 WHIP and 93:25 K:BB over 61.1 innings.

Manager Aaron Boone said Thursday that Loaisiga (elbow) will miss the remainder of the season due to a right flexor strain, Chris Kirschner of The Athletic reports.

The 30-year-old righty will conclude the year with a 4.25 ERA, 1.48 WHIP and 25:10 K:BB across 29.2 innings. Although Loaisiga's season was cut short by an injury, he reportedly won't need to undergo surgery to address the issue, which significantly boosts his chances of being available for the start of the 2026 campaign.

Matz worked around a hit in a scoreless inning to earn the save in Thursday's 3-2 victory over the Orioles.

With Aroldis Chapman having pitched twice in Boston's last three games, it was Matz who was called upon to protect a one-run lead in the ninth inning. The southpaw would surrender a leadoff double to Dylan Carlson, though he'd be erased on a fielder's choice as Matz cruised to his second career big-league save. The 34-year-old Matz has been impressive out of the bullpen since joining the Red Sox at the trade deadline, allowing just one run on six hits through his first 11.1 innings.

The White Sox recalled Booser from Triple-A Charlotte on Thursday.

Before beginning a four-game set against the Yankees, the White Sox will add a fresh arm to their bullpen in the form of Booser. The 33-year-old southpaw owns a 4.85 ERA and 1.35 WHIP through 26 innings in the majors this year and will likely work in middle relief while in Chicago. Tyler Gilbert was optioned to Triple-A in a corresponding move.

The White Sox optioned Gilbert to Triple-A Charlotte on Thursday.

Gilbert was pummeled for six runs while recording just one out in a relief appearance Wednesday versus the Royals and finds himself back in the minors a day later. Cam Booser will absorb Gilbert's roster spot.

Sterner struck out the side in a perfect inning during Wednesday's 7-0 win over the Tigers.

Sterner retired the side on strikeouts in the eighth inning Wednesday, the first time this season he's done so in order. The right-hander has been sharp in August, posting a 1.98 ERA and 0.59 WHIP across 13.2 innings in 11 appearances.

Cruz (shoulder) threw a light bullpen Wednesday, Anne Rogers of MLB.com reports.

Cruz took a step forward in his rehab for right shoulder tendinitis, throwing a short bullpen session of 15 to 20 pitches. The right-hander had previously been limited to flat-ground work from about 75 feet, so this progression is encouraging. While the Royals haven't provided a firm timeline, a late-season return remains on the table.

Harvey (groin) completed a light bullpen session Wednesday, Anne Rogers of MLB.com reports.

Harvey took another step forward in his recovery from the Grade 2 right adductor strain that has sidelined him since Aug. 11. He threw a short bullpen session of about 15 to 20 pitches, and while it wasn't a full workload, simply getting back on the mound is an encouraging sign in the right-hander's quest to return before season's end. Harvey's 2025 season has been marred by injuries, but he's delivered when available by tossing 12 scoreless appearances.

Guerrero (elbow) began a rehab assignment with High-A Greenville on Tuesday and worked around three walks and one hit in a scoreless inning in his first appearance.

The one-inning outing marked Guerrero's first appearance at any level since June 27, as he's been on the shelf for two months while recovering from a right elbow strain. Guerrero is expected to eventually shift his rehab assignment to Triple-A Worcester, and once he gets a few more minor-league appearances under his belt, he could re-emerge as an option for Boston's bullpen.
