rsvman2 I highly doubt Phil will ever win the US Open. He had two incredible chances; at Winged Foot he decided to try a hero shot from the trees instead of punching out, took a double, and lost by a single shot. Can't remember the venue, but who can forget him air-mailing the straightforward par 3 16th hole to take bogey and lose to Justin Rose by a single shot?
Winged Foot was 2006 - Ogilvy got up and down for par from short of the 18th to win by 1, with Montgomerie and Mickelson both making double bogey on the last hole to finish one shot behind. (Furyk was also T2 after bogey to finish, and Harrington finished 2 behind with three bogeys to finish.)
Rose's US Open was 2013 at Merion - the sixth time that Mickelson had finished second at the US Open (to Stewart at Pinehurst in 1999, Woods at Bethpage (2002), Goosen at Shinnecock (2004), Ogilvy at Winged Foot (2006), Glover at Bethpage (2009), Rose at Merion). The best opportunity of those was probably 2004 - 1 ahead with 2 to play, but a double at 17 and a Goosen birdie left him 2 shots behind.
