6 incredible feats Mickelson achieved with win on Sunday

It still seems unbelievable to say, but Phil Mickelson is the winner of the 2021 PGA Championship at Kiawah Island.

Though the title itself is the biggest achievement for the week, there are a number of feats Mickelson accomplished with a victory at the challenging South Carolina layout.

Here are the most incredible six:

50 years old: Mickelson become the oldest man ever to win a major championship with the victory on Sunday. The previous record-holder was Julius Boros, who claimed the 1968 PGA Championship at just over 48 years old.

2,864 days: Mickelson's last major victory came at the 2013 Open Championship when he blitzed Muirfield with a final-round 66 to win by three strokes.

45 wins: A victory on Sunday gives Mickelson his 45th career victory on the PGA TOUR, matching Walter Hagen for the eighth-most ever. His last win on the circuit before the PGA Championship came at Pebble Beach in 2019.

30 years: Mickelson burst onto the PGA TOUR scene as an amateur just over 30 years ago with a shocking one-stroke victory at the Northern Telecom Open in 1991. The win now gives him a TOUR title in the 1990s, 2000s, 2010s, and 2020s.

No. 116: Mickelson entered Kiawah Island as the 116th-ranked player in the world. Sunday's win represents the lowest-ranked player to claim a major since Shaun Micheel won the 2003 PGA Championship at No. 169, according to Justin Ray of TwentyFirstGroup.com.

6th major title: Only 13 players had previously won at least six major championships in men's golf. Mickelson became 14th with a victory on Sunday. The win represents his second PGA Championship after claiming the 2005 event to go alongside three Masters and the 2013 Open Championship. He also has six runner-up finishes in the U.S. Open, with the 2021 event being played close to home next month at Torrey Pines.
