At the 2012 U.S. Open, Westwood was in contention again after firing a three-under-par round of 67 in the third round to position himself three strokes behind the leaders. During the final round, Westwood lost his ball in a tree on the par-four fifth hole after his drive clattered into the pines. The ball was declared lost and he had to play his third shot from the tee, resulting in a double-bogey six which effectively ended his challenge. He finished in a tie for 10th.
