The White Sox traded Banks to the Phillies on Tuesday, Robert Murray of FanSided.com reports.
Through 48 innings with the White Sox, Banks has posted a 4.13 ERA and 1.29 WHIP. Chicago's lack of reliever depth has forced him to work often in high-leverage situations this season, though it's likely he moves into a middle-relief role upon joining a more talented Phillies bullpen.
