WATCH: Rory McIlroy Smashes Bunker In Anger At US Open

Rory McIlroy showed some serious anger during day one at the US Open after finding a tricky lie atop a bunker and duffing it out.

Rory's tee shot on the drivable par-4 4th hole nestled in the thick rough on the edge of a bunker and all he could do was duff it out into the next one. He was clearly annoyed at the lie he had found on a hole that offers up a real birdie chance, as he then proceeded to smash the sand in anger twice.

Watch the clip:

Luckily for McIlroy, he went on to splash his next bunker shot to around 10ft and holed a great putt to save his par and stay bogey-free for the day. He was two-under-par at the time after 13 holes, having made a superb start to the US Open.
