The White Sox placed left-hander Cam Booser and right-hander Davis Martin on the 15-day injured list on Friday.
Those were part of five moves ahead of Chicago’s series opener against the host Toronto Blue Jays.
Booser has a left shoulder strain and Martin has a right forearm strain. Martin’s designation is retroactive to Tuesday.
Booser, 33, is 1-4 with a 5.11 ERA and one save in 30 relief appearances.
Martin, 28, is 2-7 with a 3.79 ERA in 14 games (13 starts) this season.
The White Sox also recalled right-hander Wikelman Gonzalez from Triple-A Charlotte, selected the contract of left-hander Jake Palisch from Double-A Birmingham and designated right-hander Caleb Freeman for assignment.
Neither Gonzalez, 23, nor Palisch, 26, has pitched in the majors.
Freeman, 27, made his MLB debut on May 5 and posted no decisions and a 5.40 ERA in five relief appearances.
