Cairndhu's Neil McKinstry might have been tied for the overnight lead but he was in a class of his own in the end as he fired rounds of 66 and 70 to storm to an impressive 10-shot victory in the Ulster Youths Amateur Open at Belvoir Park.

A brother of Ryan McKinstry, the 2011 champion, University of Ulster golf scholarship student Neil has certainly put the pressure on younger brother (and Boys international) Marc to follow suit.

A son of the talented scratch man John McKinstry, Neil stormed to the turn in four under 32 in the morning round, then eagle the 10th before dropping his only shot of the day at the 16th.

His 66 was worth a four-shot lead over Killarney's Tommy O'Driscoll but in the end he more than doubled his lead, carding a 70 to finish on six under, 10 clear of fellow Cairndhu man Stephen Watts with O'Driscoll and Belvoir Park's  Dominic Pollock third on five over 289.
