DAYTONA BEACH, Fla. (AP) Brad Keselowski posted the fastest 10-lap average during Daytona 500 practice Friday, barely edging Kyle Busch.
Keselowski averaged 195.898 mph during the second of two sessions at Daytona International Speedway. Busch averaged 195.895 mph. Clint Bowyer was third, followed by Tony Stewart, Jeff Gordon, Joey Logano and Mark Martin. Denny Hamlin, Martin Truex Jr. and AJ Allmendinger rounded out the top 10.
Only 16 cars took the track in the morning session, and 23 turned laps in the afternoon.
Eleven drivers, including former Daytona 500 winners Kevin Harvick and Jamie McMurray, didn't even leave the garage. Many teams avoided practice because they don't have backup cars and were wary of causing damage.
Drivers have one final chance, a 90-minute session Saturday, to get on track before Sunday's opener.
