Loaisiga (back) began a rehab assignment Sunday with Triple-A Scranton/Wilkes-Barre and struck out a batter while allowing one hit and one walk over one scoreless inning.

Loaisiga was placed on the 15-day injured list Aug. 3 due to right mid-back stiffness, but his ability to begin a rehab assignment two weeks later suggests he won't be in line for an extended stay on the shelf. The right-hander had submitted a 4.25 ERA and 1.48 WHIP while collecting one save and seven holds over 29.2 innings before landing on the IL.

Armstrong earned his fourth save of the season during Sunday's 10-4 win over the Blue Jays, striking out one batter across 1.1 innings.

The Rangers turned to Armstrong to get the final out in the eighth after Hoby Milner yielded a two-run homer to George Springer and Cole Winn walked two-straight batters. Armstrong helped Texas escape the frame by getting Alejandro Kirk out and stayed on to close things out in the ninth, ending the game by striking out Myles Straw. In 14 appearances since the All-Star break, Armstrong has allowed just one run on five hits and two walks while striking out 16 over 13.1 innings.

Weissert (4-4) took the loss and blew a save during Sunday's game against Miami, allowing two runs on two hits with no strikeouts over one-third of an inning.

The Red Sox called upon Weissert in the ninth inning Sunday, as closer Aroldis Chapman got the day off after pitching in back-to-back games. Weissert inherited a one-run lead, but he surrendered a leadoff homer to Dane Myers on his second pitch of the inning. The 30-year-old reliever departed the contest with a runner on first in favor of Steven Matz, who yielded a go-ahead two-run homer to the first batter he faced. Weissert has now blown seven of his 10 save chances, and he yielded multiple runs in an outing Sunday for the first time since July 2.

Mederos is slated to start Monday's game against the Reds in Anaheim.

Mederos will receive a second turn through the rotation despite an underwhelming performance in his first career big-league start this past Tuesday. The right-hander took a no-decision against the Dodgers, covering four innings and striking out three batters while allowing three hits and three walks. Mederos will tentatively line up for a two-start week, but a poor showing against the Reds could prompt the Angels to go in a different direction the next time his turn comes up Sunday versus the Cubs.

Hatch (2-0) earned the win Sunday over the Tigers, allowing a run on three hits and three walks over five innings. He struck out four.

Hatch, making his first start this season, was impressive against a Detroit team that had scored 15 runs in their previous two games. In 13.2 innings with Minnesota, Hatch has pitched to a 3.29 ERA with a 1.54 WHIP and 9:11 K:BB. The 30-year-old right-hander could get another look in the rotation while Simeon Woods Richardson (illness) and Matt Festa (shoulder) are sidelined. Hatch would tentatively line up for a road matchup with the White Sox in his next outing.

The Tigers optioned Hurter to Triple-A Toledo on Sunday.

Hurter hasn't given up an earned run in his past nine appearances and has a 2.45 ERA in 38 major-league appearances this season, so it's a tough-luck demotion for the left-hander. The 26-year-old also had a 2.58 ERA over 45.1 innings with the Tigers in 2024, so he should be back up with Detroit before the end of the season.

The Angels designated Brogdon for assignment Sunday.

Brogdon will lose his spot on the Angels' 40-man roster after he coughed up four earned runs over 1.1 innings between his last two relief appearances to bring his ERA up to 5.30 across 37 outings on the season. The Angels recalled right-hander Jose Fermin from Triple-A Salt Lake to replace Brogdon in the bullpen.

The Tigers recalled Hanifee from Triple-A Toledo on Sunday.

The right-hander was optioned to Toledo in early August but is back with the Tigers for Sunday's series finale in Minnesota. Hanifee has made 46 relief appearances for the Tigers this season and has recorded 11 holds with a 3.10 ERA, 1.32 WHIP and 35:12 K:BB over 52.1 innings.

The Angels recalled Fermin from Triple-A Salt Lake on Sunday.

Los Angeles designated right-hander Connor Brogdon for assignment to clear room on the active roster for Fermin. Over his prior two stints with the big club this season, the 23-year-old Fermin turned in a 6.63 ERA, 1.79 WHIP and 24:14 K:BB in 19 innings. The right-hander will likely handle a low-leverage role out of the Angels bullpen.

Hatch is slated to start Sunday's game against the Tigers at Target Field, Evan Woodbery of MLive.com reports.

Minnesota will have a couple of holes in its rotation until Simeon Woods Richardson (illness) and Pablo Lopez (shoulder) return from the injured list, and Hatch will fill one of those vacancies Sunday. The right-hander should be able to provide the Twins with some length after making two 4.1-inning bulk-relief appearances since Aug. 6. Between his stops with the Twins and Royals this season, Hatch owns a 5.59 ERA, 1.76 WHIP and 6:8 K:BB in 9.2 innings over three outings.
