The Red Sox are going to have a couple new faces in the bullpen starting Tuesday night.

With righty John Schreiber heading to the injured list and lefty Brennan Bernardino being optioned to Triple-A, the Red Sox are calling up right Justin Garza and lefty Ryan Sherriff to take their place.

Garza, 29, was recently claimed off waivers from the Los Angeles Angels and has appeared in 21 big league games, all with Cleveland in 2021. He has posted a 4.71 ERA over 28.2 innings in his MLB career, and since the start of 2022 he has pitched exclusively at Triple-A. This season he has a 3.95 ERA over 13.2 innings split between Salt Lake and Worcester.

Sherriff, 32, signed with the Red Sox as a minor league free agent this past offseason and was considered a potential contender for the Opening Day bullpen out of camp. The lefty has posted a 3.65 career ERA in four big league seasons between 2017-21 with St. Louis and Tampa Bay, and this season he has a 3.00 ERA in 15 appearances with Worcester.

The moves likely won’t be the only ones coming for the Red Sox pitching staff in the coming days. Kutter Crawford is expected to be activated ahead of Friday’s series opener in San Diego, and the Red Sox could move one or possibly two starters to the bullpen as part of a larger starting rotation shakeup once Garrett Whitlock makes his return in the next couple weeks.
