Padraig Harrington has endured a disappointing start to his final round with bogeys on the second and third and seventh holes.
A birdie on the sixth pulled one back but at four under he is now eight shots off the lead.
Leading the field overnight was Finland's Mikko Ilonen. He is just out on the course with second place Danny Willett and they have both parred the first.
Best of the Irish Graeme McDowell started the day in third place and after two holes is still on his opening score of 10 under.
The North's Michael Hoey is having the best round of the day so far. He picked up three shots on the front nine, and an eagle on 10 and another birdie on 12 means he has now pulled level with McDowell.
Darren Clarke earlier finished for the day and the tournament at one over. Peter Lawrie shot two under today, giving him a final score of four under.
Irish amateur Gary Hurley shot two over today and finishes up at eight over for the tournament.
