SONOMA (CBS/AP) — Clint Bowyer raced to his first victory on a road course, and first with Michael Waltrip Racing, by holding off Kurt Busch at Sonoma.
Bowyer dominated Sunday's race by leading 70 of the 112 laps. Defending race winner Busch, in an unsponsored car, was all over the bumper of Bowyer's Toyota late and got a final shot at taking the win away when caution flew with four laps remaining.
Only Busch damaged his car with roughly eight laps to go, and he worried the entire caution period whether his Chevrolet was ruined and had no chance of catching Bowyer through the two-lap overtime sprint to the finish.
Bowyer raced side-by-side with Busch at the green flag, then cleared Busch and pulled away for the win. Bowyer, who left Richard Childress Racing at the end of last season to join MWR, had to walk to Victory Lane to celebrate with his new crew after his car ran out of gas.
"I'm super excited for everybody involved," Bowyer said. "To switch teams like I did was a huge risk and a chance for me, and it was a chance to showcase my talents."
It was a strong day all-around for MWR, which got a fourth-place finish from Brian Vickers, who was back to NASCAR after racing last weekend at Le Mans. Martin Truex Jr. led 15 laps, and was running in the top-10 until a late-race incident dropped him to 22nd.
"Everybody is just working together," Bowyer said. "That's something we are very proud of."
Tony Stewart passed Busch on the final lap to claim second.
"Got it by default there, to a certain degree," said Stewart, who was second for the second consecutive week.
Busch wound up third. He was emotional after — Busch missed Pocono earlier this month because he was suspended by NASCAR for verbally abusing a media member — and said he was thrilled to compete for the win in an underfunded, unsponsored Phoenix Racing car.
"It's an amazing day, when you can do what we did," Busch said. "I'm a little choked up because A: We were in position. B: I was very considerate to Bowyer, who was going for his first win with the new team. And then C: which is most important, I made a mistake, I got into those tires in turn 11."
Busch, who has struggled with his temper on and off the track, saw a silver lining in his strong finish.
"If I can get my head on straight here, and after the race, then I could be able to race every weekend and go for victories," Busch said.
Vickers was fourth for MWR, followed by Hendrick Motorsports teammates Jimmie Johnson and Jeff Gordon.
Greg Biffle was seventh, followed by pole-sitter Marcos Ambrose, AJ Allmendinger and Joey Logano.
Most everyone believed the race would be a runaway win for either Ambrose or Gordon, but neither really contended. Ambrose led the first 11 laps before plummeting through the field, and Gordon led one time for 13 laps before running out of gas as he was headed in for a scheduled pit stop.
There were only two cautions — the fewest in track history for the Sprint Cup Series.
