3.0: The average finish Joe Gibbs Racing teammates Matt Kenseth and Kyle Busch have posted in the first three races of the 2013 Chase for the NASCAR Sprint Cup. Kenseth won at Chicagoland and New Hampshire and ran seventh in Sunday's AAA 400 at Dover. Busch was second in each of the first two Chase races and fifth at the Monster Mile. Though the two drivers have scored identical average finishes over the last three weeks, Kenseth, the Chase leader, has extended his advantage over third-place Busch from three points at the start of the Chase (based on five wins to Busch's four in the first 26 races) to 12 after Dover, thanks to bonus points earned for winning two races and leading the most laps in the first two events.
