Aumont signed a minor league deal with the White Sox on Monday, Josh Norris of Baseball America reports.
Aumont once rated as a top-100 prospect and was included in a Clif Lee trade, but he has yet to do much in his 46 career major league appearances, and he did nil in the Blue Jays' organization after signing mid-2015. He will attempt to resurrect his career in a White Sox's organization that has previously revived previously-heralded arms.
