Masters 2012: Triple-bogey costs Phil Mickelson

Three-time Masters champion Phil Mickelson's tee shot hits the grandstand railings and goes into the trees on the par-three fourth hole on his way to a triple-bogey six.

Mickelson had been one shot off the lead of Louis Oosthuizen after the first three holes of his final round at Augusta and admits afterwards that it was this hole that cost him the chance of claiming a fourth green jacket.

Mickelson finished in a tie for third place on eight under-par, two shots behind Oosthuizen and eventual winner Bubba Watson.
