Paul Dunne fired a rollercoaster 66 to move up the leaderboard at the Hero Indian Open in New Delhi, but he still trails leader Terry Pilkadaris, who added a 64 to his opening 67, by nine shots after the second round.

Dunne had an extraordinary round which contained eight birdies, an eagle, two bogeys and a double bogey. He found himself two over par after four holes and looking at a missed cut but completed the remaining holes in eight under to ensure his place for the weekend on a total of four under par 140.

Pádraig Harrington and Michael Hoey both failed to make the cut after rounds of 74 and 75 respectively.
