Wallace takes Grand-Am win

Wallace took advantage of a door-banging exchange between Jan Magnussen and Max Papis to win the Grand Prix of Miami. The Briton was teamed with Venezuelan racer Milka Duno, who became the first female driver to win an American sportscar race overall.

Seven laps from the finish, Papis and Magnussen roared down the frontstretch side-by-side, slamming into each other. As they approached the first turn, Magnussen, driving on the inside, spun out as a tyre went down on his Lexus-powered Doran. Papis, his driver's-side door knocked ajar by the impact, went off course. His tyres damaged, Papis wasn't able to maintain the lead.

Wallace, holding steady in third with his Howard-Boss Motorsports Crawford-Pontiac, assumed the lead and held it to the finish, leading to a joyous celebration with Duno.

"I was able to stay close, but I couldn't quite catch them," Wallace said. "I kept thinking, 'If only they would start banging together, I could find a way to get through.' When I saw them going down the front straight like that, I thought, 'This is the place.'"

On the 100th lap, Papis' car was smoking noticeably, possibly the result of earlier contact with Magnussen's car. As the two emerged onto the frontstretch, Papis' Chip Ganassi/Felix Sabates entry repeatedly slammed into Magnussen's Doran Enterprises car. Magnussen eventually spun after a particularly hard hit as the cars entered the first turn. Seconds later, Papis was out of the race, too.

Magnussen and Papis met with Grand-Am stewards after the race. A Grand-Am official said a review would take place and penalties were expected to be handed down.

"I can't believe he took me out," said Magnussen, who was teamed with Didier Theys in the Doran entry. "He hit me so hard on the front stretch that it broke my suspension. I spun around and just stopped. He hit me maybe six or seven times, but I didn't once turn the steering wheel in on him."

Boris Said and Bill Auberlen teamed to win the GT class by finishing 12th overall in the Prototype Technology Group BMW M3. David Murray and Craig Stanton won the SGS title in The Racers Group Porsche GT3 RS.

The story of the day, though, was the slam-bang finish that led to a historic result.

"This is wonderful," Duno said. "It's just too much."
