"It gave us a good opportunity to run a bit quicker lap than maybe what the car had in it."[6] He was joined on the front row of the grid by Edwards.[7] Johnson qualified third, Kyle Busch took fourth, and Marcos Ambrose started fifth.[7] Denny Hamlin, Ryan Newman, Keselowski, Vickers, and Montoya completed the first ten positions on the grid.[7]
