Frustrated Phil Mickelson swats moving ball with putter at U.S. Open

Phil Mickelson's 48th birthday took a freakish twist on Saturday as he was penalised for deliberately hitting a moving ball in the third round of the US Open.

Mickelson, who turned 48 on Saturday, hit a moving ball at the par-4 13th hole at Shinnecock Hills Golf Club.

He then took a quick jog over to the ball and hit it as it still seemed to be moving.

"I don't mean disrespect by anybody", Mickelson told Fox. With the two-shot penalty, he was given a sextuple-bogey 10 on the hole and was 10 over for his round.

He said, 'I don't know what [my] score that is. "He's putted bad enough that I think he just snapped at how bad his speed was on that putt". It looked like the ball was going to fly off the green when Mickelson hit the ball back towards the hole while it was still moving - which is illegal. He carded a 10 on the hole for a 5 over par.

The five-time major champion, who just needs a U.S. Open title to complete his career grand slam, shot an ugly 11-over 81 in Round 3 while showing some clear disdain for Shinnecock Hills.

'It was going to go down in the same spot behind the bunker. The action stunned the commentators, and Mickelson's comeback put lipped out of the hole. "At that time, I just didn't feel like going back and forth", he told unusual. "I've had it with the USGA and the way they run their tournaments".

The 48-year-old slipped down the leaderboard with four bogeys around the turn before racking up a sextuple-bogey during a freaky incident at the par-four 13th. "The last time I saw something like that was John Daly at the '99 [U.S.] Open at Pinehurst".
