Phil Mickelson, for a long time, believed that the Open Championship was the least likely of the four majors for him to be victorious.
Well, that all changed in the 142nd Open Championship at Muirfield.
A week earlier, Mickelson figured out the intricacies of links-style golf in Scotland with a win at Castle Stuart in the Scottish Open. Riding that momentum, Mickelson showed up more confident than ever at Muirfield.
On an incredible Sunday that featured four birdies over his final six holes, Mickelson closed with an amazing, 5-under 66 to capture his fifth career major championship.
Mickelson ended the Open at 3-under 281, three strokes better than runner-up Henrik Stenson.
With the victory, Mickelson became the third player to qualify for golf's most exclusive foursome, joining Masters champ Adam Scott and U.S. Open winner Justin Rose in the 2013 PGA Grand Slam of Golf to be played Oct. 14-16, 2013, at Port Royal Golf Course in Southampton, Bermuda.
Mickelson began the final round of the Open Championship trailing 54-hole leader Lee Westwood by five shots. Following a steady front nine, it was those last six holes that earned Mickelson arguably his greatest win to date.
The PGA Grand Slam of Golf features a $1.35 million purse, with the winner receiving $600,000, second place $300,000, third place $250,000 and fourth place $200,000.
TNT's prime-time broadcast of the event reaches a worldwide audience of 88.9 million U.S. homes and international viewers in more than 100 countries. The PGA Grand Slam of Golf is hosted by the Bermuda Department of Tourism, Port Royal Golf Course, and the Fairmont Southampton Hotel.
Established in 1979, the PGA Grand Slam of Golf has grown from an 18-hole, single-day charity event to a 36-hole annual showdown that matches professional golf's best against each other.
The final spot in the foursome will be filled out by the winner of the 95th PGA Championship, August 8-11, at Oak Hill.
