Rory McIlroy, 2011 PGA Championship
McIlroy entered the 2011 PGA as the favorite, having run away with his first major two months earlier at the U.S. Open. On the third hole of the first round, McIlroy's drive came to rest on a tree root. Instead of taking a drop, McIlroy took a swing. His club hit the root, and McIlroy injured his wrist. He had it wrapped and played on, eventually finishing tied for 64th.
