The White Sox announced a series of roster moves before Sunday’s game against the Tampa Bay Rays. With a sweep in front of the home fans at Guaranteed Rate Field on the line, the White Sox recalled right-hander Prelander Berroa from Triple-A Charlotte, selected the contract of right-hander Brad Keller, optioned right-hander Jonathan Cannon to Charlotte and designated right-hander Deivi Garcia for assignment.
The moves come after Pedro Grifol told reporters on Saturday that the bullpen had been heavily taxed early in the season.
