BROOKLYN, Mich. (AP) -- Greg Biffle drove to an easy victory, pulling away from gambling teammate Mark Martin at the end of the NASCAR Nextel Cup race Sunday at Michigan International Speedway.

Biffle, the only driver to win both the Busch and Craftsman Truck series championships, took the GFS Marketplace 400 for his second career Cup win. He has struggled through much of his second full season in the series.

To get his first win since the July race at Daytona last year, Biffle had to hold off longtime Cup star Martin, who overcame a mistake in the pits to get back to the runner-up spot.

Martin and crew chief Pat Tryson chose to take only two tires on their final pit stop, while Biffle and the rest of the leaders took four. That gave Martin track position, but he was unable to come close to chasing down Biffle's Ford. More
