Rory McIlroy admitted frustration had got the better of him as he damaged one of his clubs in the final round of the US Open at Merion.
McIlroy drove into the water on the par-four 11th and then hit his approach into the creek short of the green as well, the world number two then leaning on the offending iron so hard he bent the shaft out of shape.
That meant he could not use the club for the rest of the round as he ran up a quadruple-bogey eight on the hole and a closing 76 to finish 14 over par.
"I just hit a bad tee shot into the creek there and what you don't want to do as a golfer is follow one mistake with another, and that's what I did," McIlroy said. "And obviously I got a bit frustrated there.
"It's a hole that you want to try to take advantage of. It's a hole that you want to at least give yourself a birdie chance and you walk off with a quad and it's not very good.
"I think that's what this tournament does to you. At one point or another it's got the better of you, and it definitely did this weekend.
