Phil Mickelson wins 2006 Masters
Moving day at the 2006 Masters was the turning point for Mickelson, as he played well enough through poor weather conditions to surge from four strokes back of the lead to one stroke ahead of the field.

Phil Mickelson wins 2010 Masters
Mickelson entered the final round of the 2010 Masters one stroke behind Lee Westwood, but a 67 on moving day served as an indication of what was to come on Sunday. Mickelson posted another 67 in his final round, surging to 16-under par and easily clearing the rest of the field. Westwood finished three strokes behind, while a dominant 65 from Anthony Kim wasn't enough to make up the gap.
At the time, Mickelson's 16-under par was only two strokes behind the 72-hole record at the Masters. The record has since been broken and is now 20-under par, but Mickelson delivered one of the most consistent performances in Masters history to capture his third title and fourth major championship.

The U.S. Open championship remains elusive for Mickelson, despite a whopping six runner-up finishes in the event. Mickelson finished second or tied for second in 1999, 2002, 2004, 2006, 2009 and 2013, but the U.S. Open is still the only major he hasn't won. With 2025 likely his final U.S. Open appearance, the career grand slam is nearly out of reach for Lefty.
Still, Mickelson can look back on more than three decades of success at the U.S. Open, including a one-stroke gap between himself and the great Payne Stewart at the classic 1999 U.S. Open.

Phil Mickelson wins 2013 Open Championship
Mickelson moved one step closer to the career grand slam with his first Open Championship win and fifth major title in 2013. Winning required a dominant final round.
After entering Sunday trailing by five strokes at 2-over par, Mickelson shot a 66 to jump eight players on the leaderboard and still win by three strokes. 54-hole leader Lee Westwood unraveled by shooting a 75, and Mickelson was able to win comfortably despite entering the day with fairly distant odds.
The victory looked like it might be Mickelson's final major title, but he overcame a slump and injury concerns to win the PGA Championship at age 50 in 2021.
