TALLADEGA, Ala. (AP) – Brad Keselowski won a demolition derby at Talladega Superspeedway, where multiple wrecks caused two cars to go airborne and led to millions of dollars in damage to race teams.

Keselowski’s cruise to the checkered flag was anticlimactic Sunday compared to all the other trouble.

Chris Buescher’s car flipped three times in an early crash, and Matt Kenseth was turned upside down in the waning laps. In Kenseth’s accident, Danica Patrick hit hard into an energy-absorbing wall that that seemed to buckle upon impact. She appeared shaken after the hit.

There were 21- and 12-car accidents in the final 28 laps. And, as Keselowski crossed the finish line, another wreck in the back of the pack punctuated the sloppy day.

Only 21 of the 40 cars finished on the lead lap, and 12 cars were ruled out of the race.
