Carl Edwards claimed his first Sprint Cup Series win of the season and with Joe Gibbs Racing after he conserved enough fuel in the late going of Sunday's Coca-Cola 600 at Charlotte Motor Speedway -- NASCAR's longest race of the season.

Edwards joined JGR at the start of this season to drive the team's new fourth car, the No. 19 Toyota. He snapped a 31-race winless streak in the series. After he and crew chief Darian Grubb elected not to pit during a late-race round of stops, Edwards took over the lead with 21 laps to go and then crossed the finish line 4.8 seconds ahead of his closest competitor, Greg Biffle.

Hamlin led the way late in the race but had to pit unexpectedly with 37 laps to go due to a loose wheel. He was also suffering from a migraine headache at the time and had to receive treatment at the track's infield medical care center after the finish.

Busch competed in his first Sprint Cup points-paying race this season after he suffered a fractured right leg and left foot during an accident in the Feb. 21 Xfinity Series race at Daytona. He ran all 400 laps around this 1.5-mile track and scored his first 33 points this year.

Dale Earnhardt Jr. finished third, while Martin Truex Jr. came in fifth after leading the most laps with 131.

Ryan Newman placed sixth, followed by Brad Keselowski. Kevin Harvick, the defending Sprint Cup champion, and Kurt Busch completed the top-10. Busch led a total of 118 laps.

Jimmie Johnson, who won last year's Coca-Cola 600, finished 40th after he was involved in an accident on lap 274 and spent close to 30 laps in the garage for repairs. Johnson spun out while exiting turn 4 and then pounded the inside wall at the entrance of pit road. A SAFER barrier had recently been installed on the wall where Johnson hit. He also spun in the same area but did not hit anything on lap 90.
