Vaughn (leg) is not starting Sunday's game against the Red Sox.
The rookie should still be considered day-to-day as he works through leg soreness. Manager Tony La Russa figures to be especially cautious with Vaughn as he's been with other key players on the division-leading White Sox, so a trip to the injured list is not out of the question. Jose Abreu is DH'ing Sunday with Yasmani Grandal filling in at first base.
