Rory McIlroy has admitted that he gives up too easily when he is struggling on the course during tournaments.

The world number two has missed four cuts in his last five tournaments but insists that he is working on his mental strength.

McIlroy said: "Definitely in the past, if things haven't gone my way, the fight goes out of me pretty quickly.

"That's something I'm working on and trying to get better at."

The 23-year-old will tee off in his home country of Northern Ireland in the Irish Open later today.
