Miller received a hydrodissection procedure on the ulnar nerve in his right elbow earlier this week, Evan Woodbery of MLive.com reports.

The procedure was to help with inflammation surrounding the nerve in Miller's elbow. He started the season strong with five scoreless outings, but he has taken the loss in two of his last four appearances, giving up five runs on four hits and three walks while striking out two across three innings over that span. Miller was placed on the 15-day IL on Monday, and he is eligible to return in late May.

Bachman (shoulder) threw live batting practice Friday, Rhett Bollinger of MLB.com reports.

Bachman began throwing off a mound May 7, and Friday marks another major step in his recovery from offseason shoulder surgery. The 24-year-old righty will almost certainly require a lengthy rehab assignment before the Angels think about adding him to their rotation, though the team has not yet specified when his assignment will start.

The Astros recalled Mushinski from Triple-A Sugar Land on Friday.

Since being optioned to Triple-A on April 12, Mushinski has appeared in 12 games for Sugar Land, registering a 4.15 ERA, 1.00 WHIP and 14:5 K:BB over 13 frames. The southpaw has not yielded a run over his last six minor-league outings, and he'll provide left-handed depth out of the bullpen for Houston. The Astros optioned right-hander Shawn Dubin to Triple-A Sugar Land in a corresponding move.

Green (shoulder) is expected to make a rehab appearance Sunday with Triple-A Buffalo, Shi Davidi of Sportsnet.ca reports.

Green has been nursing a right shoulder strain since mid-April but seems close to returning to the big-league roster. Assuming he doesn't endure any setbacks, Green should rejoin the Blue Jays before the end of the month.

Bautista (elbow) played catch Friday, Danielle Allentuck of TheBaltimoreBanner.com reports.

Bautista is continuing to rehab from October 2023 Tommy John surgery and a follow-up procedure in February. While a 2024 return hasn't been ruled out and Friday's progress is encouraging, it's highly unlikely Bautista will be back on a mound for the O's this season.

Dubin was optioned to Triple-A Sugar Land on Friday, Chandler Rome of The Athletic reports.

Less than 24 hours after collecting his first career big-league save in a three-inning appearance, Dubin was sent down to Triple-A. In a corresponding move, Parker Mushinski was called up. Through 13.2 innings with the Astros, Dubin has logged a 6.59 ERA with a 13:7 K:BB.

Devenski (knee) began a rehab assignment at Triple-A Durham on Friday.

Devenski will take the next step in his recovery from right knee tendinitis, an injury that's kept him sidelined since April 24. It's unclear how long of a rehab assignment he'll need, but he's on track to return before the end of May.

Harris was optioned to Triple-A Las Vegas on Friday.

Harris was called up Wednesday and fired off 3.1 scoreless frames Thursday against the Astros. However, he'll go right back to Triple-A on Friday to make room for Brandon Bielak, who was acquired via trade Thursday. In 25 innings at Las Vegas, Harris owns a 7.56 ERA with 23 walks allowed.

Muller could follow starter Mitch Spence as a long reliever during Friday's game against the Royals, Martin Gallegos of MLB.com reports.

With the A's rotation plagued by injuries, Muller was initially an option to start Friday's series opener. However, Oakland will hand the ball to Mitch Spence -- who's gone three or more innings six times this season -- to start the contest. Still, Muller could follow Spence and see multiple innings of work if needed.

Spence will start Friday in Kansas City, Martin Gallegos of MLB.com reports.

It will be the first major-league start for Spence, who has posted a 4.26 ERA and 22:7 K:BB over 25.1 innings covering 11 relief appearances. The Rule 5 pick will be pitching on three days' rest after allowing two runs over two-thirds of an inning Monday in Houston, so he likely won't be able to pitch deep into Friday's contest. Spence has gone three-plus frames in six of his relief appearances, including a season-long 4.2-inning outing May 5 versus the Marlins. He could wind up piggybacking with Kyle Muller, who is also available to work multiple innings.
