Will Venable is a busy man these days. The new manager of the Chicago White Sox is learning his way around the organization. As Venable assembles his first coaching staff with Chicago, he has at least one name in mind: Grady Sizemore, interim manager for the White Sox at the end of last season. “There'll be a role for him,” Venable said Friday after slipping on his new No. 1 Chicago jersey during a news conference at Guaranteed Rate Field.
