Bido allowed four runs on three hits and two walks while striking out five over three innings in a no-decision versus the Tigers on Tuesday.

Bido had posted a 3.18 ERA over 17 innings as a reliever since his July 10 call-up from Triple-A Las Vegas. He didn't fare as well as a starter, giving up a grand slam to Riley Greene in the third inning, though the Athletics were able to quickly reclaim the lead in their half of the frame. Bido threw 44 of 66 pitches for strikes in this outing. For the season, he's at a 5.66 ERA, 1.58 WHIP and 54:27 K:BB through 68.1 innings over 20 appearances (10 starts). He's projected to make his next start at St. Louis and could stick in the rotation as the Athletics navigate the absences of Jack Perkins (shoulder), Jacob Lopez (elbow) and Luis Severino (oblique).

Topa allowed a run on two hits in one inning of work while earning a save over Toronto on Tuesday. He struck out one batter.

Topa was given a 7-4 lead in the ninth inning and worked around an RBI double by Daulton Varsho to convert the save chance. It was Topa's fourth save of the year, and they've all come since Aug. 5. He's converted all four of his save chances and earned one hold since the trade deadline. During that span, Topa owns a 1.53 ERA across 11.2 innings.

Hoffman (8-5) yielded four runs on three hits and a walk while taking a loss against the Twins on Tuesday. He recorded two outs and was charged with a blown save.

Hoffman served up a leadoff homer to Mickey Gasper to immediately blow the save opportunity. Matt Wallner then ripped with a three-run shot to put the game out of reach. It's the first time Hoffman has given up more than one run in an outing since he coughed up three runs against the Athletics on July 11. Since then, he had posted a 1.84 ERA over 15 appearances. Hoffman has blown three of his last five save chances and has converted 28 of his 35 chances this season. His ERA jumped to 4.77 through 54.2 innings after Tuesday's rough outing. If his struggles continue, Brendon Little or Yariel Rodriguez could be in line to see some ninth-inning work.

Enns will serve as the Orioles' opening pitcher for Wednesday's game against Boston, Matt Weyrich of The Baltimore Sun reports.

Enns has pitched in several high-leverage situations since joining the Orioles at the trade deadline, but he'll be taking the hill for at least the first inning of Wednesday's contest. The 34-year-old southpaw has posted a 3.97 ERA and 1.50 WHIP across 11.1 innings with the Orioles, and although he's pitched as many as five innings in an appearance in the majors and six innings in the minors this season, he'll likely only remain in Wednesday's game for a frame or two before handing the game over to bulk reliever Roansy Contreras.

The Astros placed Rooney on the 15-day injured list Tuesday with left elbow inflammation, Brian McTaggart of MLB.com reports.

He will be eligible to return Sept. 9, but with the nature of the injury, Rooney might need more time than that. The lefty reliever has made one appearance for Houston this season, surrendering one run over 1.1 frames.

The Astros recalled Blubaugh from Triple-A Sugar Land on Tuesday, Brian McTaggart of MLB.com reports.

Blubaugh has made one start and two relief appearances for the Astros this season, yielding 11 runs (six earned) with a 15:3 K:BB over 13 innings. He will pitch out of the bullpen.

The Red Sox recalled Moran from Triple-A Worcester on Tuesday, Jen McCaffrey of The Athletic reports.

Moran has permitted three runs with a 5:3 K:BB over four innings covering two relief outings for the Red Sox this season. He will give manager Alex Cora another lefty in the bullpen.

The Red Sox will recall Moran from Triple-A Worcester prior to Tuesday's game in Baltimore, Chris Cotillo of MassLive.com reports.

He'll take the roster spot vacated by Richard Fitts (biceps). Moran has made a couple relief appearances with the Red Sox this season, allowing three runs with a 5:3 K:BB over four innings. The lefty has often been used for multiple innings during his outings in the majors and minors this season, so he'll offer the bullpen some length.

The Orioles transferred Blewett (elbow) to the 60-day injured list Tuesday.

The right-hander has been sidelined by elbow discomfort since July 13, and he now won't be eligible to be reinstated until mid-September. Blewett has pitched for three MLB clubs this season and has a combined 5.48 ERA, 1.42 WHIP and 35:18 K:BB over 44.1 innings.

The Orioles designated Bowman for assignment Tuesday.

Bowman allowed two runs over 1.1 innings in his lone appearance during what was his fourth stint with the Orioles this season. He's accepted three previous outright assignments from Baltimore and could do so again.
