Keith Horne made the cut, while Shaun Norris, Hennie Otto and James Kingston fell short of the one-under-par mark at the end of day two in the Irish Open at Killarney Golf and Fishing Club.
Horne, Norris and Otto began the day at one-under, while Kingston was level-par, but of the four it was only Horne who managed to hang on and he carded a level-par round of 71.
Jaco van Zyl led the way with his second round of one-under for a tournament score of two-under, but the only player after him who did not shoot over par was Horne.
Horne overcame yesterdayÂs double-bogey on the 11th and went on to birdie the hole in todayÂs round, but an unfortunate bogey on the final hole set his score back to level-par.
An opening double-bogey must have shaken Hennie Otto, who carded four-over before the turn and could not recover his round, despite a valiant bogey-free back nine which included birdies on the 14th and 18th.
Shaun Norris made par through the first five holes, but struggled to find fairways and subsequently carded a round containing seven bogeys and his second round of five-over left him out of contention.
James Kingston had to withdraw from the tournament after he battled through 13 holes.
Defending Champion Ross Fisher moved to seven-under and claimed his share of fourth with a strong round of three-under. He currently two shots behind leaders Milkha Jeev Singh and Noren Hansen ahead of the third day.
Horne has made the cut and must look now to the third round to go further under par and find success in Ireland.
