The Yankees reinstated Effross (hamstring) from the 15-day injured list Sunday and optioned him to Triple-A Scranton/Wilkes-Barre.

The right-hander opened the campaign on the injured list due to a hamstring strain he suffered at the start of spring training, and he won't immediately join the big-league club upon being activated. Effross hasn't seen significant action in the majors since 2022, when he had a 2.54 ERA, 1.06 WHIP and 62:15 K:BB in 60 regular-season appearances between the Cubs and Yankees.

The Astros claimed Alexander off waivers Sunday and optioned him to Triple-A Sugar Land, Matt Kawahara of the Houston Chronicle reports.

The right-hander was designated for assignment by the Athletics on Friday but will retain a spot on the 40-man roster with a new organization. Alexander gave up 12 earned runs over six frames in the majors but has a 1.69 ERA in five starts at the Triple-A level this season.

The Angels selected Strickland's contract from Triple-A Salt Lake on Sunday.

The veteran right-hander will join the Angels just two weeks after signing with the organization on a minor-league deal. Strickland opened the year in the minors with the Rangers but was granted his release after giving up 14 earned runs in 12 appearances. He was an effective bullpen option for Anaheim last year with a 3.31 ERA and 12 holds over 73.1 innings.

The Royals recalled Bowlan from Triple-A Omaha on Sunday.

The right-hander has spent most of the campaign with Omaha, where he produced a 2.08 ERA, 0.99 WHIP and 25:5 K:BB over 17.1 innings. Bowlan delivered two scoreless frames in his lone big-league appearance of the campaign.

The Orioles recalled Strowd from Triple-A Norfolk on Sunday.

The right-hander was promoted for one day in late April and will rejoin the Orioles with Kyle Gibson being designated for assignment. Strowd has a 7.47 ERA and 25:7 K:BB over 15.2 innings for Norfolk this season and is looking to make his MLB debut.

The Rangers optioned Winn to Triple-A Round Rock on Sunday.

The right-hander was called up from Triple-A on Thursday and delivered 2.1 scoreless frames Friday in his season debut for the Rangers. Winn will return to Round Rock, where he's started the campaign with 23.1 scoreless innings out of the bullpen.

The Rangers recalled Boushley from Triple-A Round Rock on Sunday.

The 31-year-old was sent down Thursday but will rejoin the big-league roster ahead of Sunday's series finale versus Houston. Boushley has made six appearances in the majors so far this year and has a 4.50 ERA, 1.08 WHIP and 12:3 K:BB over 12 innings.

Whitlock walked one over a scoreless eighth inning in Saturday's 7-6 win over Atlanta.

Whitlock had been brutal of late, entering the contest with a 10.80 ERA and four blown saves over his previous five outings. While he did issue a walk and allow a hard-hit flyout, it was an encouraging performance for the right-hander.

Martin (elbow) threw a scoreless inning in Saturday's 5-1 win over the Astros.

Martin recently dealt with elbow tightness and hadn't pitched since Tuesday, but imaging came back negative. With closer Luke Jackson (hand) still dealing with an injury, Martin could snag save opportunities in the short term.

The Twins placed Coulombe on the 15-day injured list Sunday due to an extensor strain in his left forearm.

It's unclear when Coulombe sustained the injury since he hasn't pitched since Wednesday. The left-hander hasn't given up a run through 19 appearances this season and owns a stellar 19:2 K:BB over 16.2 innings out of the Minnesota bullpen, but he'll now be unavailable for at least the next couple weeks.
