SONOMA, Calif —
"It's OK. We got a top-10 out of it," Ambrose said. "I wanted to win. Of course I wanted to win, but that's the way it goes."
Greg Biffle was eighth and followed by Jimmie Johnson and Kevin Harvick in the top 10.
The race got off to an inauspicious start before it even began with a pit road accident, a mechanical issue for Jacques Villeneuve and an oil line failure for Bobby Labonte.
The accident occurred as the cars were headed onto the track and David Reutimann stopped his car on pit road. Alex Kennedy stopped behind Reutimann, and Paulie Harraka slammed into the back of Kennedy.
The damage wasn't significant enough to prevent Harraka from making his Sprint Cup Series debut. But it was a short-lived race for the first driver to advance from NASCAR's diversity program into a Cup race — Harraka spun and crashed his car six laps later.
Meanwhile, a parts failure caused Labonte to dump oil all over pit road before the race and he was forced to take his car to the garage for a quick repair. Labonte made it onto the track for the green flag, but his engine failed on the first lap.
"It blew up, dude," Labonte said on his radio. "Something in the bottom engine because it had no oil pressure."
Villeneuve had an issue shifting his gears and had to stay on pit road for a quick repair before trying to catch up to the field at the start of the race. He made it, but the problem wasn't completely corrected and he was back on pit road after 19 laps for more repairs.
Busch had back-to-back speeding penalties in yet another race that slipped away. He led 15 laps, lost the lead to former teammate Brad Keselowski, then was flagged for speeding when he went in for a scheduled pit stop. He had to return to pit road for a stop-and-go penalty and was flagged for speeding again.
