Kyle Busch led most of the second half of today's race and appeared on the way to his third win of the season. But he seemed to have tire trouble off the restart that came after the caution with seven laps left.
Keselowski was there to take advantage and the checkered flag, perhaps taking away some of the sting of failing to qualify for Sunday's Cup race.
Joey Logano was second and Clint Bowyer third. Brian Vickers and Carl Edwards rounded out the top five.
Busch led the most laps for the fifth consecutive race, but has only one win over that span. He finished 17th.
