KIAWAH ISLAND, SC — Winning a major professional golf championship at age 50 or older is something no one had ever pulled off, until Phil Mickelson accomplished the feat Sunday afternoon with a win at the 2021 PGA Championship at the Ocean Course in Kiawah Island, South Carolina.

Mickelson clinched the PGA Championship win, and oldest major win distinction, by finishing at 6-under after the final round of the four-day tournament on Sunday. Louis Oosthuizen, of South Africa, and American Brooks Koepka tied for the runner-up at 4-under.

Mickelson’s age on Sunday — 50 years, 11 months and 8 days — makes him two years older than the next oldest golfer to win one of professional golf’s four major tournament championships.

Before Mickelson’s PGA Championship win on Sunday, Julius Boros was the oldest golfer to win a major with his 1968 PGA Championship win at age 48. Tom Morris Sr., winner of the 1867 Open Championship and Jack Nicklaus, the 1986 Masters Tournament champion, both notched major victories at 46.

Sunday’s PGA Championship win was the sixth major championship for Mickelson, and the first since his 2013 Open Championship title. He’s also won the Masters three times — 2004, 2006 and 2010 — and the 2005 PGA Championship.
