Michael McDermott shot a sensational 65 to win the nett prize at Naas’ Conor O’Rourke warmed up for international duty with a gross win in the opening Tuesday Winter Series outing of 2017 at Portmarnock Hotel and Golf Links.

McDermott’s six under par round ave him six shots to spare over the GUI National Academy’s Niall McGlynn and seven over Spawell’s Ross Young in the nett.

But scoring was also red hot in the gross with St Andrews Links Trophy holder O’Rourke, who will join Alex Gleeson in the South American Amateur Open in Buenos Aires later this month, carding a four under 67.

The Naas player won the gross by four shots from Thomas Mulligan and by six from Portarlington’s Karl McCormack on a day when 72 players teed it up.

Mulligan will join Irish Boys champion Mark Power, Leinster Boys champion John Brady, West of Ireland champion Jonathan Yates and his fellow Naas man Rob Brazill as well as Clement Ader’s Eamonn O’Driscoll and Kilkenny’s Luke Donnelly in the Copa Andalucía at Real Club de Golf Guadalmina in Spain from January 9-12.
