Denny Hamlin

Denny Hamlin is undefeated on the season after winning the second Daytona 500 qualifying race, that ended with a violent last-lap crash in which Clint Bowyer's car flipped upside down.

Back on top with only two NASCAR legends left to catch, Jimmie Johnson won his sixth Sprint Cup championship in eight years Sunday to stake his claim as one of the most dominant competitors in sports history. Now looming large in Johnson's windshield is the mark of seven titles held by Richard Petty and the late Dale Earnhardt.

Denny Hamlin promised he would be a factor in Sunday's NASCAR race at Martinsville Speedway, and he went out and proved it by leading a parade of drivers who smashed the track qualifying record.

Denny Hamlin has another top spot in his comeback from a back injury. Hamlin turned a lap of 157.978 mph Friday to win the pole at Dover International Speedway. He won the pole last week at Charlotte Motor Speedway and has three overall this season.

Denny Hamlin broke the track record Thursday with a lap of 195.624 mph to capture the pole for the Coca-Cola 600 on Sunday at Charlotte Motor Speedway.

Matt Kenseth takes the lead with 13 laps left to win his first Southern 500 at Darlington Raceway.

Denny Hamlin has received medical clearance to return this weekend at Talladega Superspeedway.

Denny Hamlin suffered a compression fracture in his lower spine during a last-lap crash while racing for the win against former teammate Joey Logano, and Joe Gibbs Racing gave no indication Monday how long its driver could be sidelined.

At Auto Club Speedway on Sunday, Kyle Busch took the checkered flag by flying by the dueling machines of Joey Logano and Denny Hamlin. Plus Tony Stewart goes after Logano for an earlier dust-up on the track.

Kasey Kahne's bumper-banging battle with Brad Keselowski was just the warm-up act in an action-packed race at Bristol Motor Speedway.
