The White Sox recalled Severino from Triple-A Charlotte on Tuesday.

With starting pitcher Lucas Giolito (abdomen) and outfielder AJ Pollock (hamstring) moving to the injured list, the White Sox have opted to replace them on the 28-man active roster with a righty and lefty reliever in Jimmy Lambert and Severino, respectively. Severino, who has yet to appear in the big leagues, narrowly missed out on a spot in Chicago's Opening Day bullpen. He didn't allow any home runs in the minors last season and racked up 53 strikeouts across 45.2 innings between Triple-A and Double-A Birmingham, but a 16.5 percent walk rate likely took him out of the mix for a promotion to the big leagues in 2021. Expect him to work in low-leverage spots for the White Sox initially.
