Irish Open round two: Everything you need to know as McIlroy among five Irish players to make the cut despite more putting problems
Read back on all the action from Friday at Ballyliffin on our live blog
The second day at the Dubai Duty Free Irish Open will be remembered most for a catastrophic Irish collapse.
Padraig Harrington, who had been one behind the overnight leader after round one, missed the cut care of a disastrous four over par back nine on Friday.
- Irish Open Saturday LIVE: Updates as McIlroy and McDowell aim to make up lost ground on leaders at Ballyliffin
Thursday's leading Irishman hit the self destruct button, culminating in a double dogey six at the last to miss the cut.
A lost ball on the par five 13th contributed to his first double of the day that added to four more bogeys and left him +2 for the weekend and outside the cut mark after 15. Back to back birdies on 16 and 17 looked to have saved him but a three-putt double bogey on 18 ended any chance of making it through.
Meanwhile, Shane Lowry and last weekend's qualifying winner Simon Thornton are now the best placed locals. They both shot comparatively delightful -2 rounds to sit -2 for the week, eight back of the leaders.
Rory McIlroy finished at -1 for the tournament after a disappointing second round one over par 73. A bogey, bogey finish was the climax of a frustrating couple of days in which putting problems were the main issue. It's no exaggeration to say that, had the putter worked, he could be leading the tournament.
Graeme McDowell has just about made it to the weekend. He birdied both short par fives but added three bogeys to leave him one over for the day and squeaking into the weekend on level for the week.
Paul Dunne sneaked through on the cut-mark of +1 but there was a Harrington-style disaster for Ruaidhri McGee who doubled his final hole to miss the weekend by a shot.
At the top of the leaderboard on -8 are Ryan Fox and Matthieu Pavon, who shot -3 and -4 respectively, as well as South African Erik Van Rooyen, who carded the week's lowest score; a seven under 65 on day two.
