The Orioles activated Selby (hamstring) from the 15-day injured list Tuesday, Jake Rill of MLB.com reports.

Selby strained his left hamstring July 28 but is healthy after completing a rehab assignment. The 27-year-old right-hander has recorded a 4.09 ERA, 1.55 WHIP and 12:2 K:BB across 11 innings this season for the Orioles.

The Angels optioned Peralta to Triple-A Salt Lake on Monday.

The move corresponds with the Angels reinstating Ryan Zeferjahn (knee) from the 15-day injured list. Peralta joined the big club Sept. 7 after spending most of the season in Triple-A, but in just four major-league appearances he allowed 12 runs (nine earned) on 14 hits and six walks while striking out seven across 9.2 innings.

The Angels reinstated Zeferjahn (knee) from the 15-day injured list Monday.

Zeferjahn landed on the 15-day IL in early September due to right knee tendinitis, but he has been cleared to return to the majors despite not going on a rehab assignment. The 27-year-old right-hander posted a 3.20 ERA, 1.17 WHIP and 31:11 K:BB across 19.2 innings in 19 games since the All-Star break.

Vargas allowed one run on one hit in 1.2 innings Sunday against the Astros. He struck out one.

Vargas has been a liability out of the Seattle bullpen of late, giving up at least one run in three of his last four outings. The right-hander has mostly worked as a middle reliever and in low-leverage situations in 2025, and that's unlikely to change at this stage of the season while the Mariners try to clinch a playoff berth. Through 74 frames, Vargas has a 4.01 ERA, 1.35 WHIP and 51:23 K:BB with 14 holds while converting just one of his eight save opportunities.

Ferguson allowed one run on three hits in one-third of an inning Sunday against the Astros.

The Mariners acquired Ferguson from the Pirates ahead of the trade deadline to bolster their bullpen, but he hasn't been particularly reliable for his new team. Through 18.1 innings for Seattle, the southpaw has a 3.93 ERA, 1.53 WHIP and 14:7 K:BB. Given Ferguson's shakiness, Gabe Speier will likely remain the preferred left-handed high-leverage arm for the M's in the future.

Aldegheri will start Tuesday's series opener versus the Royals in Anaheim, Jeff Fletcher of The Orange County Register reports.

The Angels recalled Aldegheri from Triple-A Salt Lake on Thursday after Jose Soriano (forearm) was placed on the injured list in a corresponding move, and since Aldegheri wasn't needed out of the bullpen in the Halos' weekend series in Colorado, he'll end up slotting into Soriano's spot in the rotation. Though he was tagged for seven runs (five earned) in 4.1 innings over his prior two long-relief appearances with the big club earlier this summer, Aldegheri has excelled since the All-Star break while pitching out of the rotations for Salt Lake and Double-A Rocket City, notching a 2.43 ERA, 1.04 WHIP and 44:15 K:BB in 55.2 innings. Unless the Angels elect to expand the rotation to six men, Aldegheri will tentatively line up for two starts during the last week of the season, with his second turn set to come in Sunday's finale versus the Astros.

Cantillo did not factor in the decision during Sunday's loss to Minnesota. He allowed a run on four hits and two walks over 4.1 innings while striking out five.

Cantillo gave up his lone run in the third inning. He loaded the bases in the fifth but was not charged with any runs after Erik Sabrowski cleaned up the mess. Cantillo has given up fewer than two runs in six consecutive outings; during that span, he's produced an impressive 1.32 ERA across 34 frames. However, he's also walked 12 batters during that time and has issued 28 free passes in his last 12 starts. Cantillo owns a 3.21 ERA with a 100:42 K:BB through 89.2 innings this season. He's expected to make his final start of the regular season next weekend at home against the Rangers.

Hoffman earned the save in Sunday's 8-5 win over the Royals, allowing one hit and zero walks in a scoreless ninth inning. He did not record a strikeout.

Hoffman got the call to protect the Blue Jays' three-run lead in the ninth. He yielded a double to Mike Yastrzemski, but Hoffman closed things out by getting Bobby Witt and Vinnie Pasquantino to both ground out, and the win clinched the Blue Jays a spot in the postseason. Hoffman has had his struggles this season but has not given up a run in each of his last four outings. He has a 3.71 ERA and 1.24 WHIP across 26.2 innings while converting on 10 of 13 save opportunities since the All-Star break.

Spence (3-6) took the loss Sunday against the Pirates, allowing seven runs (six earned) on nine hits and two walks over 3.1 innings. He struck out one.

Spence struggled out of the gate Sunday, allowing a pair of two-out runs in the opening inning before the Pirates added on with a two-run homer in the second. It's the first start and second appearance for Spence since he was recalled from Triple-A earlier this month. Overall, the right-hander sports a 4.96 ERA with a 1.41 WHIP and 65 strikeouts across 81.2 innings this year.

The Tigers selected Rainey's contract from Triple-A Toledo on Sunday, Evan Petzold of the Detroit Free Press reports.

Rainey began the season with the Pirates, accumulating an ugly 10.57 ERA and 1.70 WHIP over 7.2 innings spanning 11 appearances. He was released in early July and subsequently signed a minor-league deal with Detroit. Since joining the organization, Rainey has been effective with Toledo, posting a 2.52 ERA, 1.12 WHIP and 35:14 K:BB across 25 innings. He'll likely fill a low-leverage spot in the Tigers bullpen over the final week of the campaign. Charlie Morton was designated for assignment Sunday to make room for Rainey on the 28-man active roster and 40-man roster.
