Busch, Denny Hamlin, Truex Jr. and Edwards led a group to pit road for fresh rubber in preparation for a restart on Lap 378. Gordon was leading when the sixth caution flew on Lap 389 for Sam Hornish Jr.'s wreck on the backstretch. That set up the five-lap dash to the finish.
Busch ran away with the first half of the race, leading all but eight of the first 229 laps before Burton powered past him in Turn 3 on Lap 230. Burton held the top spot for 20 laps, only to surrender it to Gordon, whose car came to life in the middle of a long green-flag run.
"I have no idea how this has just happened—but I'm liking it," Gordon radioed to crew chief Steve Letarte after the pass for the lead. Gordon extended his advantage through a cycle of green-flag pit stops, and by Lap 300 he had stretched his advantage over Harvick to 2.878 seconds.
Notes: Edwards led Laps 269 and 270 during a cycle of green-flag pit stops. Those were the only laps he has led this year, ending a 12-race drought dating to Talladega in November 2009. … Busch gave Dave Rogers his first victory as a Sprint Cup crew chief.
