Dale Earnhardt Jr. scraped the wall in a race billed as his final Cup Series start at Daytona International Speedway. He drove his JR Motorsports Chevrolet to his first career win last weekend at Iowa.
Clint Bowyer was second, followed by Paul Menard, Michael McDowell, Ryan Newman and Ragan.
As 40 cars were entered, all drivers made the field for tonight's race. The most spectacular was a nine-car mess on the front straightway in lap 153 of the 160-lap race that began when Kyle Larson's auto went airborne, was T-boned by Brad Keselowki and Matt Kenseth and briefly caught fire before it slid onto the grass.
Larson and four other drivers were evaluated at the infield hospital and released.

Planes were grounded for almost an hour, which meant unprotected firefighters on the ground also had to back off from their work. More than 1,200 firefighters have seen action battling the blaze that has charred 40 square miles (104 square kilometers).
In a single auto incident, Earnhardt hit the Turn 1 wall on Lap 52 of Saturday night's Coke Zero 400 and then limped his vehicle around the track to get repairs on pit road.
Earnhardt was the pole-sitter and overwhelming favorite to win the Saturday night race at Daytona.
Earnhardt's team repaired the damage, although he dropped two laps down.
