Bristol, TN (My Sportsbook) - Kyle Busch did not have the dominant car of the night, but he saved his best for last to win Saturday's Sharpie 500 and record a season sweep at Bristol Motor Speedway.

Busch, who won the spring race at Bristol earlier this year, grabbed the lead with 68 laps to go and then held off Mark Martin in several late-race restarts, including the final one for a four-lap shootout, to claim his fourth victory of the season and the 16th of his Sprint Cup Series career.

Martin furiously challenged Busch after the final restart, but ended up finishing one car length behind. He had dominated most of the race by leading 240 of 500 laps.

Marcos Ambrose finished third, while Greg Biffle and Denny Hamlin rounded out the top-five.

With the victory, Busch moved up two positions to 13th in points and trails 12th-place Matt Kenseth by 34 points with two races to go before the "Chase for the Sprint Cup" championship begins. Martin also climbed two spots to 10th in points.
