Kyle Busch locked up his spot in the Chase for the Sprint Cup championship with his fourth victory of the year Sunday night at Atlanta Motor Speedway.

Busch emerged with the lead after a rapid-fire series of caution flags near the end, and he held off hard-charging Joey Logano to win by 0.740 seconds.

Martin Truex Jr, racing with a broken right wrist, took third on the 1.54-mile trioval, followed by Kurt Busch and Ryan Newman.

The rest of the top 10: Jeff Gordon, Juan Pablo Montoya, Dale Earnhardt Jr., Kevin Harvick and Brian Vickers.
