Mickelson produced one of the most improbable wins in the game's history in May 2021. At age 50, the left-hander won the 2021 PGA Championship at Kiawah Island's Ocean Course to become the oldest major champion. With six majors to his name, Mickelson now seeks to complete the career Grand Slam after six runner-up finishes in the one major that has eluded him, the U.S. Open. A week before his PGA triumph, Mickelson received a special exemption from the USGA to play in this year's championship. His PGA win was his 45th on the PGA Tour. His previous major win before the PGA was the 2013 Open Championship at Muirfield, where he carded a final-round 66. He also owns three Masters victories, in 2004, 2006 and 2010. He also won the PGA Championship in 2005 at Baltusrol Golf Club in Springfield, N.J. A 2012 World Golf Hall of Fame inductee, Mickelson has 55 worldwide wins. His only USGA title came in the 1990 U.S. Amateur at Cherry Hills Country Club outside of Denver over fellow San Diegan Manny Zerman. He represented the USA in the 1989 and 1991 Walker Cup Match and is a three-time NCAA individual champion. As a professional, he has competed on 12 USA Ryder Cup and 12 Presidents Cup teams.
