Watkins Glen, N.Y. Kyle Busch won the Centurion Boats at The Glen at Watkins Glen International, becoming the first driver in NASCAR history to win three road course races in one season.
After a red-flag stoppage following a multicar pileup with eight laps to go, Busch held off Joe Gibbs Racing teammate Tony Stewart, who was bidding for his fifth victory here in his last seven starts. Marcos Ambrose of Tasmania, who started last, finished third a day after winning the Nationwide race.
Busch has won 16 races in NASCAR's top three series this season - eight in Sprint Cup, six in Nationwide and two in trucks - and three came on road courses. He won the Nationwide race in Mexico in April and the Cup race at Sonoma in June before finishing second Saturday in the Nationwide race.
