NASCAR Watkins Glen Results 2012: Marcos Ambrose, Brad Keselowski Have Memorable Finish (VIDEO)

In a wild final two laps that rivaled any race in recent memory for unrelenting action, Marcos Ambrose out-dueled Brad Keselowski to win Sunday's Finger Lakes 355 at Watkins Glen International.

Kyle Busch had the lead at the white flag, but slid in a patch of oil exiting Turn 1 on the final lap. Keselowski likewise slid in the oil, hit Busch's No. 18 Toyota and spun it. For the rest of the final lap, Ambrose and Keselowski raced side-by-side for the lead, with Ambrose finally clearing the No. 2 Dodge in the last corner.

The victory was Ambrose's second straight at Watkins Glen and the second of his NASCAR Sprint Cup Series career. Jimmie Johnson finished third and took over the series lead by one point over Greg Biffle, who wound up sixth. Clint Bowyer was fourth, followed by Sam Hornish Jr., Biffle and Busch.

Tony Stewart finished on the bottom end of a roller-coaster day. Starting from the rear of the field for dragging a gas can from his pits under caution on Lap 27, Stewart charged toward the front and was running second to Keselowski when he spun in Turn 7 on Lap 72 and backed his No. 14 Chevy into the guardrail.

That left Keselowski and Ambrose to restart 1-2 on Lap 75 in the 90-lap race, but before the two front-row cars cleared the first corner, Busch took them three-wide to the inside and grabbed the lead. After a protracted battle with Keselowski, Ambrose took over the second position on Lap 81 but couldn't gain ground on the race winner.

Keselowski retook the second position in Turn 5 on Lap 89 -- and then the fireworks started.
