Jimmie Johnson dominated again at Dover International Speedway, extending his track record for wins with nine.
He followed last week's victory in the Coca-Cola 600 with another sensational run in a race red-flagged for 22 minutes because of a pothole in the concrete track.
Johnson led 272 of 400 laps, and won consecutive races for the 13th time. The six-time Cup champion swept Dover in 2002 and 2009 and won races in 2005, 2010, 2012 and 2013.
Brad Keselowski was second, followed by Matt Kenseth, Clint Bowyer and Denny Hamlin.
Johnson also became Dover's career leader in laps led when he hit the 2,802 mark.
Carl Edwards finished 14th.
