Rory McIlroy said he will need to turn flashes of brilliance into firing on all cylinders for his final two rounds as he aims to win the British Open on home soil at Royal Portrush. 

The Masters champion sits at three under par, five behind clubhouse leader Brian Harman, after the opening two days of his return to Northern Ireland. 

After a rollercoaster first round that contained five birdies, four bogeys and a series of wild tee shots, McIlroy was more controlled on his way to a 69 on Friday.
 
“I feel like my game’s definitely good enough to make a run,” McIlroy told reporters.
