Gavin Green holds a three-shot lead at the halfway stage of the Czech Masters after carding a 63.
The 28-year-old Malaysian's nine-under round was the lowest of the second day at the Albatross Golf Resort course in Prague and was enough to propel him up to 14 under and clear of the trio of Marcel Schneider, Richard Mansell and Thomas Pieters who followed Thursday's 65 with a four-under 68.
Cormac Sharvin was best of the Irish, with his 69 lifting him to four under. He managed five birdies but bogeyed seven and 18.
David Carey is one shot further back after a 70 which featured five birdies - four on the back nine - and three bogeys.
Gavin Moynihan and Paul Dunne both missed the cut. Moynihan carded a 73 to finish on level par, while Dunne finished on four over despite improving on Thursday's 76 with a 72.
