In his second race with new crew chief Darian Grubb, Hamlin shook off memories of a championship-losing run at Phoenix in 2010 by leading the final 59 laps and holding off NASCAR's best closer.
Kevin Harvick had Hamlin in his sights over the final few laps, but ran out of gas and finished second. Hamlin was concerned about gas as well, but had just enough to celebrate his 18th career win with a brief burnout.
Greg Biffle finished third and Jimmie Johnson bounced back from a disastrous Daytona 500 to finish fourth despite wheel troubles midway through the 312-lap race.
