2011 Kurt Busch #22 Shell Pennzoil Toyota Save Mart 350 Infineon Sonoma Raced Win Version 1:24 NASCAR Diecast

Busch's impressive turnaround continued Sunday with a dominating run at Infineon Raceway, where he earned his first career road course victory and his first win of the season. "We've been on a great run these last few weeks," Busch said. "To get a road course win, it's a big check mark on my list. It's just really neat to bring home that 'W."

Busch led a race-high 76 laps during the Toyota / Save Mart 350 and beat Jeff Gordon by almost 4 seconds for his first win of the season. It's a marked turn for Busch, who unraveled over his team radio at Richmond in early May because of how poorly his Dodge had been running. The rant led to behind-the-scenes changes at Penske Racing that have sparked both Busch and teammate Brad Keselowski, who won at Kansas earlier this month. Busch, despite three consecutive poles, was winless but inching closer and closer.

It finally came on a road course, of all places. Busch was winless in 10 career starts at both Sonoma and Watkins Glen, the only two road courses on the Sprint Cup circuit. And Busch helped Keselowski finish 10th with advice and a tour of the track on Friday. "It's a good feeling to know that the two teams are working as closely together as they ever have," Busch said. "Knowing that Brad is definitely maturing, seeing him bust off a top 10 at a road course is great. We went around the race track, I pointed out some of the apex points, exit points, shifting points. He absorbed it like a sponge.
