During the tournament, his wife Amy and his mother Mary were battling breast cancer and no one would have blamed Mickelson if his play reflected that.
And yet, even without a victory on the season and plenty on his mind, Mickelson came into the Masters and once again was at his best to finish 16-under at 272, three shots better than runner-up Lee Westwood.
Mickelson has a total of five major victories, but his magic at the Masters is something else.
1961: The Boston Celtics defeat the St Louis Hawks for their fourth title.
1981: Larry Holmes beats Trevor Berbick in 15 rounds for the heavyweight boxing title.
1996: The NHL’s Detroit Red Wings become just the second team in history to win 60 games in a season.
