Thielbar was placed on the 15-day injured list Friday with a right oblique strain, Betsy Helfand of the St. Paul Pioneer Press reports.

Thielbar returned from the same injury this past weekend and made just one appearance before evidently suffering a setback. He missed more than a month with the issue the first time around. Josh Winder is taking Thielbar's spot in the bullpen.

Muckenhirn could be in line for a promotion to the majors, Mike Puma of the New York Post reports.

The Mets are in need of a fresh bullpen arm and Muckenhirn appears to be the likely choice. The left-hander has yielded one run over 3.2 innings at the big-league level this season.

White (shoulder) was reinstated from the 60-day injured list Friday.

White has been on the shelf all season due to a right shoulder impingement and was pulled off his rehab assignment May 19 because of fatigue in the same shoulder. Now that he's officially off the injured list, he will likely join the Jays' bullpen in a multi-inning relief role. White logged a 7.74 ERA and 1.74 WHIP in 43 innings with Toronto last season.

Bass was designated for assignment by the Blue Jays on Friday.

Bass has put up a 4.95 ERA, 1.40 WHIP and 19:9 K:BB over 20 relief innings with the Jays this season. He also was recently reprimanded, although not suspended, after sharing an anti-LGBTQIA+ video on social media. Bass will now go through the waiver process.

Karcher was recalled from Triple-A Louisville on Friday.

Karcher was added to the 40-man roster over the offseason and will now get a chance to make his major-league debut. The 25-year-old has big stuff but often doesn't know where it's going, posting a 9.27 ERA and 31:34 K:BB over 22.1 innings with Louisville.

Salazar was optioned to Triple-A Louisville on Friday, Charlie Goldsmith of The Cincinnati Enquirer reports.

Salazar will head to Louisville after he allowed six runs on 12 hits and three walks over 9.1 innings in six appearances with the Reds. Joel Kuhnel was called up Friday and will replace him on the major-league roster.

Kuhnel was called up from Triple-A Louisville on Friday, Charlie Goldsmith of The Cincinnati Enquirer reports.

Kuhnel will return to the big leagues after he was sent down to Louisville on April 5. The right-hander has made one appearance with the Reds this season, allowing three runs on five hits and a walk over two innings against the Cubs on April 4. He's struggled to a 7.13 ERA over 24 innings in Triple-A this year, so he'll likely operate exclusively in low-leverage situations with Cincinnati. Eduardo Salazar was sent down to Louisville in a corresponding move.

Vespi was recalled from Triple-A Norfolk on Friday, Jacob Calvin Meyer of The Baltimore Sun reports.

Vespi was up with the big club briefly last month but didn't make an appearance. He's posted an impressive 1.77 ERA and 21:5 K:BB over 20.1 relief innings with Norfolk this season.

Zimmermann was optioned to Triple-A Norfolk on Friday, Jacob Calvin Meyer of The Baltimore Sun reports.

Zimmermann threw 61 pitches over three innings of relief Wednesday versus the Brewers, so he'll be replaced by a fresh arm. Nick Vespi will take his spot in the bullpen.

Lowther was released by the Orioles on Friday, Roch Kubatko of MASNSports.com reports.

Lowther had been on an injury rehab assignment but has not made an appearance this season. The 27-year-old posted a 6.94 ERA over six starts and five relief appearances with the Orioles from 2021-22.
