Tony Stewart won the rain-delayed NASCAR Sprint Cup race at Watkins Glen International on a steamy Monday, holding off Australian Marcos Ambrose over the final 25 laps for his Cup-record fifth victory at the famed road course.

Tony Stewart is on a run at Watkins Glen that has rarely been seen. He has finished in the top two in his last six races at the road course.

"I love it when it gets slick," Stewart said. "I was watching him [Ambrose]. I think we were stronger in the parts we needed to be and we never looked at the fuel."

It was Stewart's third win in his first season as an owner-driver and the seventh road course win of his career, second to Jeff Gordon's NASCAR-record nine. Stewart has six consecutive top-two finishes at The Glen, also winning in 2004, 2005, and 2007 and finishing second in 2006 and 2008. He also has finished first or second in eight of the past 11 road races; he was second to Kasey Kahne at Sonoma in June.

The race originally was scheduled for Sunday, but a string of thunderstorms forced it to be postponed until Monday. Last week's race at Pocono also was postponed to Monday because of rain.
