White Sox reliever John Brebbia out with right calf strain; lefty Shane Drohan has shoulder surgery

GLENDALE, Ariz. — The White Sox’ sizable flock of working pitchers in camp has taken a trim, from 36 to 33 including one or two notable compoments.

Veteran right-hander John Brebbia, signed to a one-year, $5.5 million contract as a free agent and expected to be a valued late-inning option for manager Pedro Grifol, sustained a right calf strain throwin live batting practice Wednesday that left him wheeling out of the Sox’ complex at Camelback Ranch Thursday on a scooter. And lefty Shane Drohan, the Sox’ Rule 5 draft pick, underwent nerve decompression surgery on his left shoulder, Grifol said.

Earlier this week, the Sox said righty Edgar Navarro is having Tommy John surgery.

Grifol and general manager Chris Getz are hopeful Brebbia can be ready by Opening Day in five weeks.

“My only question was, ‘Hey, are we going to keep the arm moving?’ ” Grifol said. “And without hesitation, all our guys said it wasn’t a problem. We are shooting for Opening day, the beginning of the season.”

Brebbia posted a 3.18 ERA in a National League high 76 appearances for the Giants in 2022 and a 3.99 ERA in 40 games in San Francisco last season, used as an opener, middle reliever and setup man.

Drohan is expected to begin a throwing program after spring training.
