Rory McIlroy cut an extremely frustrated figure out on the golf course on day one of the PGA Championship.

McIlroy succumbed to an opening-round 74 at Aronimink to leave him seven shots adrift of the leaders with three rounds left to play.

The 37-year-old Northern Irishman won The Masters for the second consecutive time last month.

However, Rory McIlroy will have to make huge improvements on day two of the PGA Championship, if he is to win his second major of the year this week.

McIlroy drove the ball really poorly on Thursday at the PGA Championship, and that cost him dearly.

His poor play was summed up by the fact that he achieved an unwanted career first in Pennsylvania.

McIlroy played the 990th round of his PGA Tour career at Aronimink on Thursday.

And things obviously didn’t go to plan for the six-time major champion.

McIlroy made just two birdies along with six bogeys during his opening round of 74.

Four of those bogeys came consecutively at the end of his round.
