Red Sox roster moves: John Schreiber placed on injured list, Brennan Bernardino optioned; Justin Garza, Ryan Sherriff called up from Triple-A Worcester

The Red Sox placed right-handed reliever John Schreiber on the 15-day injured list with a right teres major strain and optioned left-handed reliever Brennan Bernardino to Triple-A Worcester prior to Tuesday’s contest against the Mariners at Fenway Park, the club announced.

In a pair of corresponding moves, righty reliever Justin Garza was recalled from Worcester and lefty reliever Ryan Sherriff — who was not previously on the 40-man roster — had his contract selected. The Red Sox had an opening there after designating Ryan Brasier for assignment on Monday.

Schreiber felt tightness in his right lat (the latissimus dorsi muscle, on his side) after delivering a pitch to Julio Rodriguez in the seventh inning of Monday night’s 10-1 loss to the Mariners. The 29-year-old was seen flexing his throwing arm on the mound and was immediately removed from the game after a visit from manager Alex Cora and head athletic trainer Brandon Henry.

The hope is that Schreiber’s injured list stint will last the minimum 15 days, which would put him in line to return to action at the end of the month. Schreiber told reporters (including The Boston Herald’s Mac Cerullo) that he had an MRI done, but it remains to be seen if Tuesday’s diagnosis will alter his recovery timeline at all.

Bernardino, meanwhile, allowed one run on three hits over 1 1/3 innings of relief in Monday’s loss to Seattle. The 31-year-old was seen hugging and shaking hands with teammates after the game, indicating that he had indeed been sent down.

Claimed off waivers from the Mariners on April 16, Bernardino forged a 3.65 ERA and 4.77 FIP with 10 strikeouts to three walks across 11 appearances (12 1/3 innings) in his first stint with Boston. He appeared in one game for the WooSox prior to getting called up for the first time on April 24.

As for the two new additions to the bullpen, Garza — in similar fashion to Bernardino — was claimed off waivers from the Angels on April 28 and was immediately optioned to Worcester. In four relief appearances for the WooSox, the 29-year-old posted a 3.38 ERA and 3.47 FIP with eight strikeouts to just one walk over 5 1/3 innings of work.

A former eighth-round draft selection of the Guardians out of Cal State Fullerton in 2015, Garza broke in with Cleveland in June 2021 and pitched to a 4.71 ERA (5.30 FIP) with 29 strikeouts to 18 walks in 21 outings (28 2/3 innings). The California native became a free agent for the first time last November. The Red Sox had interest in bringing him in, but he instead signed a split contract with his hometown Angels in December.

Listed at 5-foot-10 and 170 pounds, Garza operates with a five-pitch mix that consists of a mid-90s sinker, a mid-80s changeup, a high-80s cutter, a mid-80s slider, and a mid-90s four-seam fastball. He will wear the No. 63 with the Red Sox.

Sherriff, on the other hand, signed a minor-league contract with Boston back in January. The soon-to-be 33-year-old southpaw has appeared in 15 games for Worcester this season and has put up a 3.00 ERA (2.94 FIP) with 16 strikeouts to eight walks over 15 innings in which he has held opposing hitters to a .211 batting average against.

Like Garza, Sherriff last got into a game at the big-league level in 2021, when he produced a 5.52 ERA (3.65 FIP) with 16 strikeouts to nine walks in 16 relief appearances (14 2/3 innings) for Tampa Bay. For his major-league career, which dates back to 2017, the 6-foot-1, 190-pound hurler owns a lifetime 3.65 ERA in 44 outings (44 1/3 innings) between the Cardinals and Rays.

Sherriff, who will wear the No. 71 with the Red Sox, throws from a three-quarters arm slot and works primarily with a low-80s slider and low-90s sinker. He joins Joely Rodriguez and Richard Bleier as lefties available to Cora out of the Boston bullpen.

Following Tuesday’s series of transactions, the Red Sox’ 40-man roster is back at full capacity. More moves will be coming soon, however, as Kutter Crawford — who has been sidelined by a left hamstring strain since May 4 — is expected to come off the injured list in San Diego on Friday.
