Joe Gibbs Racing cemented itself as the team to beat for NASCAR's championships with a dominating run Saturday night that ended in Matt Kenseth's fourth win of the season.

The win put Kenseth in a tie with JGR teammate Kyle Busch and six-time champion Jimmie Johnson for the top seeds in the Chase for the Sprint Cup championship. The 10-race playoff series begins next Sunday at Chicagoland.

Kenseth has won three of the last six races, and JGR has won eight of the last 11.

The 16-driver Chase field was set in the regular-season finale, where only four spots were really up for grabs. Jamie McMurray clinched his berth as soon as he took the green flag, but Jeff Gordon, Ryan Newman, Paul Menard and Clint Bowyer all had to protect their positions.
