Mariners' Joey Gerber: Undergoes back surgery

Gerber recently had surgery for a back issue, Ryan Divish of The Seattle Times reports.

Gerber made his major-league debut in 2020, throwing 15.2 innings for Seattle out of the bullpen. He logged a 4.02 ERA and 1.15 WHIP, though he has not logged any innings in either the majors or minor leagues this season. Though the exact nature of the injury has not been reported, Divish expects that Gerber will miss the rest of the 2021 campaign.
