Kurt Busch celebrates his win in the NASCAR Sprint Cup Series auto race at Infineon Raceway in Sonoma, Calif.
SONOMA, California (AP) — Kurt Busch has earned his first career road course victory with a dominating performance at Infineon Raceway.
Busch led a race-high 76 laps and beat Jeff Gordon by almost 4 seconds for his first win of the season.
It marked a total turnaround for Busch and his Penske Racing team, which struggled last month and made behind-the-scenes personnel changes to adapt.
Carl Edwards finished third Sunday, followed by Clint Bowyer and Marcos Ambrose.
The race featured several on-track flare-ups, most notably Brian Vickers' payback spin of Tony Stewart. The bump sent Stewart's car spinning into a stack of tires, and the rear of his Chevrolet came to a rest on top of the stack.
