Brad Keselowski faces pressure on several fronts. The Pure Michigan 400 is a home race for the Rochester Hills, Mich. native, who finished second and third, respectively, in the past two August events. Keselowski was among the big movers over the weekend in upstate New York, his runner-up finish to Kyle Busch vaulting the reigning NASCAR Sprint Cup champion to eighth in the standings. He leads 11th-place Kurt Busch by 11 points. Without a victory, Keselowski doesn’t have the luxury of a potential Wild Card Chase entry.
