A deflated Rory McIlroy admitted he needs to eliminate "silly mistakes" from his game after missing the cut in the Dubai Duty Free Irish Open for the fourth time in five years.
After labouring to an opening 72 on a day when 105 of the 156-strong field broke par, defending champion McIlroy could only add a second round of 73 at Portstewart Golf Club to finish one over par.
Outsiders Daniel Im and Benjamin Hebert are on 13 under and boast a one-shot lead but McIlroy finished five shots short of the cut mark.
"My short game is not sharp enough and I'm making silly mistakes," said the Holywood ace.
"I'm not being very efficient with my scoring which is making it difficult for myself. Maybe a little bit of course management as well. A couple of times I tried to go at pins I shouldn't have and paid the price. It's the simple things I haven't been doing well."
Graeme McDowell also missed the cut as he finished two under.
