White Sox's Gregory Infante: Heads to big leagues

Infante had his contract purchased from Triple-A Charlotte on Monday.

Calling up Infante is the corresponding roster move after Cody Asche was optioned to Triple-A Charlotte on Sunday. The 29-year-old right-hander hasn't appeared in the majors since 2010, also with the White Sox, but his stellar 2.08 ERA and 11.1 K/9 in 13 Triple-A innings this season could help him succeed in a low-leverage relief role.
