NASCAR Cup Series

Already three races into the Sprint Cup Series season Greg Biffle and company have fallen into a comfortable rhythm.

Last year, Stewart dominated and came close to winning, but found himself at the bad end of a penalty late in the race. This year, he dominated once again and was able to close the deal, holding Jimmie Johnson off coming to the checkered flag.

TONY STEWART, NO. 14 MOBIL 1/OFFICE DEPOT CHEVROLET, RACE WINNER: ON HIS VICTORY TODAY AT LAS VEGAS MOTOR SPEEDWAY: "Man, I'm just finally glad to win one here. We were so close last year and had a dominate car. I'm not sure we had the dominate car, but we had an awful fast Mobil 1/Office Depot Chevy."

GREG BIFFLE – No. 16 Meguiars Ford Fusion – WHAT WENT ON WITH YOU AND YOUR TEAMMATES AT THE END? “I don’t know if Matt was outside of me. They told me that Matt had a run at the top and Carl was inside of me and drifting up."

Brad Keselowski (No. 2 Miller Lite Dodge Charger R/T) Finished 32nd “We had a pretty decent Dodge Charger all day, probably not as good as Tony’s (Stewart) but really strong. We were going to give him a run for his money and I was going to drive my butt off."
