The American golfer got himself on the 18th green in two after shooting eight under through 17.
It was the perfect approach for Phil, offering him a makeable birdie putt to shoot a 62 and set a new major championship record round.
But it wasn’t to be – and it couldn’t have been any more devastating from the 2013 winner of this competition.
Mickelson got almost everything right, with his pace perfect and line almost spot on, but the ball turned at the last second and rimmed the hole before sitting out.
It’s as hard to watch as it is to accurately describe:

How, just HOW, does that not go in? That’s some black magic at work.
Still, Mickelson didn’t look too disappointed as he walked off the green, despite being heard on TV saying, “I can’t freaking believe that didn’t go in,” to a spectator.
His 63 ties the major record set by a whole host of players, beats the Royal Troon record by three strokes and sees him take a three-shot lead into day two of the competition.
