Saving his equipment for the final green-flag run, NASCAR Sprint Cup Series points leader Greg Biffle finally put a win on the board, cruising to a 3.235-second victory over Jimmie Johnson in Saturday night's Samsung Mobile 500 at Texas Motor Speedway.
Biffle took the lead on Lap 304 of 334 and pulled away to win his first race since Oct. 3, 2010 (at Kansas), his second at Texas and the 17th of his career. Johnson, who led a race-high 156 laps, scraped the wall trying to run down Biffle in the late going.
Mark Martin came home third, followed by Jeff Gordon and Matt Kenseth. With Kasey Kahne finishing seventh and Dale Earnhardt Jr. 10th, all four Hendrick Motorsports drivers ran in the top 10, but Biffle denied them their most coveted prize, a 200th Cup victory for team owner Rick Hendrick.
From the moment he passed pole-sitter Martin Truex Jr. for the lead on Lap 180, Johnson was dominant, as Biffle chased the five-time champion lap after lap through three cycles of green-flag pit stops.
Biffle frequently gained ground when Johnson hit traffic, but the margin would expand when Johnson got to clean air. The lead stayed at roughly one second -- give or take -- and by the time the race hit Lap 300, Martin in third at 7.8 seconds back was the only other driver within 10 seconds of the leader.
With 34 laps left, however, Biffle turned up the wick. On Lap 304, the series leader made the pass for the top spot, streaking to the inside of Johnson's No. 48 Chevrolet as the cars approached the start/finish line.
The race featured only two cautions and ended with a green-flag run of 234 laps. That was a race record, as were the average speed (160.577 mph), fewest number of cautions and fewest number of caution laps (10).
