Playing in one of the last groups, the Masham pair edged the runners-up spot, 17-16, on the back six.
Ripon City's Anthony Blackwell and Andrew Matey were fourth with the day's only 44pt total, while Otley's Mike Yeates and Nigel Roberts claimed fifth place ahead of club-mates Graham Holden and Kevin Walsh, who came sixth despite 23pts on the back nine.
Twenty two twos were scored, including four by the partnership of Tony Magrs, the Ripon City captain, and Richard Stockdale.
Magrs's came on holes three and nine while Stockdale's were carded on the 12th and 16th.
