The Astros recalled Alexander from Triple-A Sugar Land on Monday, Julia Morales of AT&T SportsNet Southwest reports.

Alexander will be joining the Astros as a replacement on the 26-man active roster for right-hander Lance McCullers (foot), whom Houston placed on the 15-day injured list. Ryan Gusto will be pushed up a day in the Astros' pitching schedule to start Monday's series opener in Sacramento, but Alexander could be called upon to start Tuesday's game against the Athletics while Houston looks to keep a six-man rotation intact during a stretch of 13 games in 13 days, per Chandler Rome of The Athletic. The 32-year-old Alexander hasn't made a start in the majors since 2022, but he made four appearances in the majors with the Athletics earlier this season and gave up 13 runs (12 earned) in six innings. Since being claimed off waivers by the Astros on May 18, Alexander has worked out of the Sugar Land rotation and has posted a 1.74 ERA, 1.26 WHIP and 15:8 K:BB in 20.2 innings over four starts.

The Tigers claimed Hernandez off waivers from the Phillies on Monday.

Hernandez had been designated for assignment after logging a 5.26 ERA, 1.75 WHIP and 23:13 K:BB in 25.2 innings for the Phillies. The hard-throwing right-hander does not have minor-league options remaining, so he will join the Tigers' active roster. Detroit will announce a corresponding transaction prior to Tuesday's game against the Pirates.

The Orioles recalled Selby from Triple-A Norfolk on Monday.

Selby has made three relief appearances for Baltimore this season, allowing two runs with a 5:1 K:BB over 3.2 innings. He'll give the bullpen a fresh arm.

The Rays optioned Englert to Triple-A Durham on Monday.

Despite tossing 4.1 scoreless innings over his two relief appearances following his promotion from Durham last Tuesday, Englert will return to the Triple-A club while the Rays make room on the active roster for newly acquired right-hander Forrest Whitley. Englert has covered 22.1 innings over 13 appearances in his multiple stints in the majors this season, pitching to a 4.84 ERA, 1.39 WHIP and 22:4 K:BB.

Triple-A Charlotte placed Varland on its 7-day injured list March 31 due to an unspecified injury.

Varland made just one appearance for Charlotte before landing on the shelf less than a week into the season. The right-hander looks to be closing in on his return to the Charlotte bullpen, however, as he began a rehab assignment in the rookie-level Arizona Complex League last week. Varland retains a spot on the White Sox's 40-man roster, so he could be in the mix for a promotion to the big club later on this season if he can get healthy and pitch well at Charlotte over an extended stretch.

McArthur (elbow) was cleared to resume playing catch a few times per week earlier this month, MLB.com reports.

McArthur has made limited progress since undergoing surgery in the offseason to address an olecranon fracture in his right elbow, but he's at least begun a throwing program after being shut down for the past several months. The right-hander has multiple checkpoints to hit during the rehab process before making his return from the 60-day injured list at some point during the second half of the season.

Harvey (shoulder) was cleared to continue playing catch after a positive re-evaluation Wednesday, MLB.com reports.

Harvey had already been playing catch every other day for the past few weeks while he works his way back from a right teres major strain, and he now looks poised to increase the intensity and distance of his throwing sessions before eventually graduating to mound work. The veteran reliever has been on the shelf since April 11 and isn't expected to return from the 60-day injured list until July.

Marsh (shoulder) resumed throwing bullpen sessions at the end of May and has continued his throwing progression at the Royals' spring training facility in Arizona, MLB.com reports.

The report doesn't specify whether Marsh has resumed facing hitters yet, but that will be the next step in his progression once he gets enough bullpen sessions under his belt. The right-hander has been on the shelf all season after suffering from shoulder soreness early in spring training and then experiencing a setback in early April. Marsh posted a 4.53 ERA and 1.26 WHIP over 129 innings across 26 appearances (25 starts) with the Royals in 2024, but the big club may not have a spot available for him in the rotation once he's ready to return from the 60-day injured list, likely at some point in July.

Hader didn't allow a hit or a walk with one strikeout over a scoreless 10th inning against the Twins on Sunday.

Hader logged his third win in four appearances, closing the door on the Twins after Houston scored runs in the ninth and 10th innings to land the 2-1 win. Despite the victory, Hader snapped a streak of eight consecutive innings with multiple strikeouts. After posting a sub-standard 3.80 ERA in 2024, Hader boasts a 1.45 ERA and a 48:7 K:BB over 31 innings in 2025.

Duran blew the save Sunday against the Astros, allowing one run on one hit and one walk with a strikeout over one inning.

Duran took the mound in the bottom of the ninth with a 1-0 lead but surrendered a leadoff walk to Jeremy Pena, who came around to score on a game-tying sacrifice fly to give Duran the blown save. It was Duran's second blown save of the campaign, and he's allowed a run in three of his last five appearances. In 33 innings this season, Duran owns a 1.64 ERA.
