To date this season, Keselowski has raced five double-duty weekends (competing in both Sprint Cup and Nationwide Series races). In those five Cup Series races he has produced two victories and two third-place finishes, Penske Racing PR reports.
Keselowski has been a double-duty ace this season. The extra racing action in the Nationwide Series has not hurt his Cup performances at all. In fact, the added seat time appears to be helping the Penske Racing star. Keselowski's two wins and four Top 5's in five double-duty starts are hard to debate against.
