The White Sox placed left-hander Cam Booser and right-hander Davis Martin on the 15-day injured list Friday.
Booser has a left shoulder strain, and Martin has a right forearm strain. Martin's designation is retroactive to Tuesday.
Those were part of five moves ahead of Chicago's series opener against the Toronto Blue Jays.
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.
Booser, 33, is 1-4 with a 5.
