DAYTONA BEACH, Fla. (AP) -- Tony Stewart won a chaotic Nationwide Series race at Daytona International Speedway that ended with a frightening last-lap crash that appeared to injure fans when rookie Kyle Larson's car sailed into the fence that separates the track from the seats. The front end of Larson's car was ripped away, and a gaping hole was cut in the fencing. Pieces of the car sailed into the grandstands and emergency workers could be seen attending to fans.
