Mediate has been featured in the top 20 of the Official World Golf Ranking and considered to be one of the best putters in golf. At the 2006 Masters, Mediate was in contention to win the event on the final day until he took a septuple-bogey ten on the par three 12th hole. His best finish in a major championship was a second place showing at the 2008 U.S. Open at Torrey Pines South Course. Tied with Tiger Woods at -1 after regular tournament play, then tied again at even par through the 18 hole playoff, Woods finally bested Mediate on the first hole (hole #7) of sudden death, the 91st hole of the tournament. It was only the third time a U.S. Open playoff had gone to sudden death. Mediate's performance gained him 111 spots in the world golf rankings, moving him from 158th to 47th place.
