Carl Edwards passed Marcos Ambrose on the final turn to win the crash-filled Nationwide race at Circuit Gilles Villeneuve, which ended with the cars on rain tires for the second straight year.

Edwards won a two-lap sprint to the finish on a track that was both wet and dry in spots from a light rain when Ambrose, who dominated the race, slid sideways after hitting the rumble strips in turn 14. Edwards slipped past Ambrose and outraced him down the final straightaway for his first career road win and the first road win for Roush Fenway Racing.

“The difference was the tires and the way the track was changing,” Edwards said. “As soon as it gets dry, there’s so much more grip, and there were places out there I saw that had a little more grip. Maybe I could just see better through my windshield.”

Ambrose survived three other restarts in the final 11 laps of the race, which was plagued by 11 cautions and went an extra lap.

“I made a mistake at the end there and just lost it,” Ambrose said. “Carl put pressure on in the hairpin. He got a great run, and it turned into a drag race. I couldn’t make the turn, bounced off the curb, and Carl slingshotted the corner. When you’re on the wrong side of it, it’s pretty tough.”

NASCAR Canadian Tire Series star Andrew Ranger was third. Former Formula One star Jacques Villeneuve finished fourth on the track named for his father, and Brad Keselowski was fifth.

Points leader Kyle Busch went from fourth to 10th on the final two laps.

Ambrose started from the pole and was out front most of the race. He led 60 laps — including 31 in a row when rain moved in for the second year in a row.

The crowd cheered when the red flag flew, stopping the race at the end of lap 61 so the teams could switch to rain tires, slap on windshield wipers, and hook up brake lights in a five-minute window.

The red flag lasted 6 minutes, 51 seconds, and the 74-lap race resumed on lap 64 with the 2.7-mile, 14-turn course damp but with no standing water like a year ago.

Raikkonen wins Belgian GP

Kimi Raikkonen held off Force India driver Giancarlo Fisichella to win Formula One’s Belgian Grand Prix, the Ferrari driver’s fourth triumph at the high-speed track in the past five years.

The former world champion, who started sixth, immediately overtook pole sitter Fisichella after the safety car came in following accidents on the opening lap — including one involving overall F-1 leader Jenson Button — and held for a 0.9-second victory.

“It’s a proper circuit, an old-style circuit,” said Raikkonen, who clinched Ferrari’s fifth win in seven races at the Spa-Francorchamps circuit. “It’s just been good to me.”

Championship contender Sebastian Vettel of Red Bull, who had retired with engine failures in the past two races, finished third to gain on Button.

Button failed to finish in the points for the first time this season, and Rubens Barrichello moved within 16 points of his Brawn GP teammate after finishing seventh despite an oil leak with two laps to go. Barrichello’s car caught fire as he rolled into pit lane.

Button leads the drivers’ standings with 72 points, followed by Barrichello with 56 and Vettel with 53.

“This championship is a little crazy, to be honest,” Vettel said. “It’s up and down. (But) we’re still in reach.”
