Who caddied for Tiger Woods during 13 of his 15 major championship victories?

Steve Williams caddied for Tiger Woods during 13 of Woods’s 15 major championship victories. The New Zealander joined Woods in 1999, replacing Mike “Fluff” Cowan, and remained his caddie until 2011.

Their partnership covered Woods’s most dominant period. Williams was on the bag for major wins including the 1999 and 2000 PGA Championships, the 2000 U.S. Open, four Masters victories, and Woods’s 2008 U.S. Open triumph at Torrey Pines. He also caddied during the 2000–01 “Tiger Slam,” when Woods held all four professional major titles at once.

The two majors Williams missed were Woods’s 1997 Masters victory and his 2008 Open Championship win at Royal Birkdale. Mike Cowan, commonly called “Fluff,” caddied for Woods early in his professional career, including the 1997 Masters. Joe LaCava became Woods’s caddie much later, beginning in 2011 after Williams’s departure.

Williams later caddied for Adam Scott, including Scott’s 2013 Masters victory, giving him 14 major wins with players overall.
