White Sox optioned RHP Gregory Infante to Triple-A Charlotte.
Infante was in the mix for the final bullpen spot, but he’s currently sidelined indefinitely after straining his left oblique on Sunday. The 23-year-old right-hander earned a September call-up last year after posting a 2.54 ERA and 54/28 K/BB ratio between Double- and Triple-A and remains a promising bullpen arm.
