By Lap 180, Edwards was able to work himself back up into the top five and on Lap 194, passed Earnhardt for the lead, taking his teammate Kenseth with him into second place just one lap later.

Kenseth then took the lead on Lap 216, when he beat Edwards out of the pits during another caution period. Kenseth and Edwards stayed 1-2 until Lap 238, when Edwards blew by Kenseth to take the lead, a lead that he ultimately would never surrender.

But the drama was far from over. Earnhardt passed Kenseth for second place Lap 252 and five laps later, Kurt Busch blew a right-front tire to bring out the 10th caution of the race. Like Stewart and Robby Gordon earlier, Busch made extremely hard contact with the wall.

The race restarted single-file on Lap 263 with Edwards leading Earnhardt, Kenseth, Gordon, Biffle, Harvick, Burton, Kahne, Ragan and Kvapil.

Earnhardt had a bad restart and Jeff Gordon jumped to second place ahead of Kenseth and Earnhardt. Gordon drifted up the hill going into Turn 2 and hit Kenseth’s car, sending the Ford spinning, though it didn’t hit anything.

But Gordon was not so lucky.

His Chevrolet shot violently across the track, hitting an opening in the inside backstretch wall with savage force. The impact was so hard that it knocked Gordon’s radiator back across the middle of the track onto the backstretch.

That incident brought out a red flag for 17 minutes and 57 seconds.

Kenseth’s car didn’t have any collision damage, but both his right tires were flat, so he had to pit for tires under caution, which dropped him from the top five to 20th in the final rundown.

At the restart on Lap 266, the order was Edwards, Earnhardt and Biffle, which is how they finished. Biffle made a couple of runs at Earnhardt to try and snatch second place, but came up short, while Earnhardt had nothing for Edwards, who cruised to victory by 0.504 seconds.

With a second consecutive victory and another race at a 1.5-mile track next week at Atlanta, the Roush Fenway Racing squad may just be getting warmed up.
