Las Vegas, NV -- Matt Kenseth celebrated his 41st birthday on Sunday by winning the Kobalt Tools 400 at Las Vegas Motor Speedway.
Kenseth gambled on tires late in the race and then held off a hard-charging Kasey Kahne in the closing laps to claim his 25th career Sprint Cup Series victory but his first with Joe Gibbs Racing. It came in just his third start with JGR's No. 20 team. Kenseth, the 2003 series champion, spent the past 13 seasons with Roush Fenway Racing.
On their last pit stops, Kenseth and Brad Keselowski took fuel only and came out of the pits first and second, respectively, while the other front runners put on two new tires. Kenseth led the final 41 laps on old tires.
Kahne, who led the most laps with 114, finished 0.6 seconds behind Kenseth. Keselowski, the defending Sprint Cup champion, finished third, followed by Kyle Busch and Carl Edwards, who won last weekend's race at Phoenix. Busch bounced back from a pit-road speeding penalty early in the race.
Danica Patrick finished six laps down in 33rd after starting 37th. The starting lineup for this race was determined by owner points since qualifying was rained out on Friday.
