Rory McIlroy inadvertently hit his father Gerry with a wayward shot as he struggled to an opening 76 on day one of the 85th Masters.

McIlroy was already two over par when he pushed his approach to the seventh hole to the right of the green, where it hit his father on the back of the leg.

The former world number one had at least shouted the traditional warning of “Fore” and Gerry was able to see the funny side, joking with reporters: “I should ask for an autographed glove.”

“I’m quite encouraged with the way I hit it on the way in. I hit some loose shots out there but after the six iron in the water on 13 I hit some really good shots.

“I’m going to go to the range to work on it a little bit more but it was just one of those days where I wasn’t very efficient with my scoring.”
