Jimmie Johnson wins again at Daytona.

Jimmie Johnson has won the Daytona double.

After winning the season-opening Daytona 500, Johnson dominated last night's Coke Zero 400 for his fourth victory of the season.

He's the first driver since Bobby Allison in 1982 to sweep both Daytona races.

Johnson is the Sprint Cup points leader.

He tied Matt Kenseth for most victories on the circuit.

The five-time NASCAR champion was the leader on the restart for a two-lap sprint to the finish in overtime.

He held off Kevin Harvick on the restart, and then pulled out front to a sizeable lead.

Tony Stewart was second, followed by Kevin Harvick in a Chevrolet sweep. Clint Bowyer (BOY'-ur) was fourth in a Toyota.
