Rory McIlroy was frustrated with his finish as Banbridge’s Richard Kilpatrick grabbed a share of the halfway lead in the AIB Irish Amateur Open at Royal Dublin.
Kilpatrick, 25, fired a one-under up par 71 to tie with reigning US Amateur champion Richie Ramsay (72) and Welshman Rhys Enoch (73) on one-over par 145.
McIlroy drove into the hazard at the 18th and ran up a bogey five for a 74 that left him two off the pace entering Sunday's final 36 holes.
The Island’s Robert McCarthy sits alone in fourth place on two over par after a 72 with McIlroy in a share of fifth place with Limerick's Pat Murray and the Finn Joonas Granberg on three-over par.
“It is just very frustrating,” said McIlroy, who had five bogeys and three birdies in his round. “I am probably being a little impatient to be honest but I should be playing better.”
Joint leader Ramsay, the winner of this title in 2005, was also disappointed with his score after getting to three-under par for his round with seven holes to play.
"I could have opened up a slight lead but I didn't finish it off,” said Ramsay. “By my standards that is not good enough. I am not out there to be content."
