He appeared as himself in a non-speaking role in the 1996 film Tin Cup, starring Kevin Costner.
His 2000 Buick Invitational win ended Tiger Woods' streak of six consecutive victories on the PGA tour.
After winning two majors in a row heading into the U. Open at Winged Foot, Mickelson was bidding to join Ben Hogan and Tiger Woods as the only players to win three consecutive majors (not necessarily in the same calendar year).
Mickelson was the joint-leader going into the final round, but he was part of a wild finish to the tournament, in which he made major mistakes on the final hole and ended up in a tie for second place at 6 (286), one shot behind Geoff Ogilvy.
In early 1993, Mickelson hired Jim "Bones" Mackay as his caddy.
He won many PGA Tour tournaments during this period, including the Byron Nelson Golf Classic and the World Series of Golf in 1996, the AT&T Pebble Beach National Pro-Am in 1998, the Colonial National Invitation in 2000 and the Greater Hartford Open in 2001 and again in 2002.
Other players to accomplish this feat include Doug Sanders (1956 Canadian Open) and Gene Littler (1954 San Diego Open).
To date, it is the most recent win by an amateur at a PGA Tour event.
Ernie Els was the runner-up at a stroke back; the two played in different pairs in the final round and had traded birdies and eagles on the back nine.
In addition to getting the "majors monkey" off his back, Mickelson was now only the third golfer with a left-handed swing to win a major, the others being New Zealander Sir Bob Charles, who won The Open Championship in 1963, and Canadian Mike Weir, who won The Masters in 2003.
