Stewart struck out nine and took a perfect game into the eighth inning before Danny Valencia hit a lead-off double. Brent Morel went 3-for-5 with a two-run single while Juan Pierre and Alexei Ramirez added an RBI apiece. Scott Diamond gave up two runs over five frames to suffer the loss. In the opener, Philip Humber tossed seven shutout innings as the White Sox topped the Twins, 2-1. Jake Peavy will toe the rubber against Liam Hendriks in tonight's third installment.
