Malaysia's Gavin Green holds a one-shot lead after the opening round of the D+D Real Czech Masters, with Paul Dunne the best of the Irish some six shots off the pace.

Green carded eight birdies in the first 12 holes and added another on the last for a round of 64.

He is a shot clear of South Africa's Erik van Rooyen and Lee Slttery of England. 

Austria's Bernd Wiesberger, who missed seven months of last season after undergoing wrist surgery, is three shots off the lead as he chases a third victory in his last eight events.

Paul Dunne had four birdies, including one at the last, as he signed for a 70. 

Gavin Moynihan is a shot further back, with Padraig Harrington, one over after a 73.
