Farquhar signed a contract with the White Sox on Monday, Daryl Van Schouwen of the Chicago Sun-Times reports.
Just four days after being released by the Rays, Farquhar has already found a new home. The right-hander struggled with command this season, but his strikeout ability could help him land a job in the big-league bullpen. For now, though, he'll act as an organizational depth piece at Triple-A Charlotte.
