Tiger Woods has won the PGA Championship four times. His victories came in 1999, 2000, 2006, and 2007, making the tournament one of the defining stages of his career.
Woods won his first PGA Championship at Medinah Country Club in 1999, defeating Sergio García by one stroke. He successfully defended the title in 2000 at Valhalla Golf Club, beating Bob May in a three-hole playoff. That victory was part of Woods's extraordinary season, which also included the U.S. Open and The Open Championship.
After several years without a PGA Championship win, Woods captured the title again in 2006 at Medinah. He then won in 2007 at Southern Hills Country Club, becoming the only golfer to win the PGA Championship back-to-back on two separate occasions.
The number is sometimes confused with Woods's total of 15 major championships. The PGA Championship is only one of golf's four men's major tournaments; Woods won five Masters titles, four PGA Championships, three U.S. Opens, and three Open Championships.
