Brad Keselowski led most of the last 192 laps and then rallied from fourth in a two-lap sprint for his second consecutive NASCAR Nationwide Series win.
The victory allowed Keselowski to begin rebuilding his series points lead, which was cut nearly in half last week after he won at Talladega and his car failed postrace inspection.
Keselowski almost led the last 192 laps, but he pitted as the leader under caution with five laps to go. He reasserted his dominance by powering through the field on new tires to pass Kyle Busch and teammate Justin Allgaier, who both stayed out, to win by 0.261 seconds.
"We made the right moves (Friday)," Keselowski said. "We had the car to beat."
Greg Biffle rallied from fifth on the restart to finish second. Jamie McMurray was third, followed by Busch and Carl Edwards. Allgaier was hurt by his late strategy, falling to 15th.
The dramatic ending served only to reinforce that Keselowski had the best car.
Earlier, he was leading by more than 3.5 seconds when a crash by Jason Leffler brought out a late caution and gave Busch an opportunity to make amends for an earlier error on pit road that dropped him from second to sixth. This time, he went into the pits fourth and came out second, lining up to the outside of Keselowski on a restart with 57 laps left.
It hardly mattered.
"We just didn't have anything for (Keselowski) tonight," Busch said. "He was so stellar."
