The Heath's Mary Doyle carded the low round of the day — a brilliant three under par 69 — to claim a share of seventh place in the Portuguese International Ladies Amateur Open in Lisbon.

The talented left-hander was the only player in the 46-strong field to break 70 and one of just three players to dip under par as she made five birdies and two bogeys at Montado Golf Club to lead the Irish challenge on four over par 292.

Joint overnight leader Silvia Bañon Ibañez of Spain had enough with a 75 to win by a stroke from England's Gabriella Cowley (70) on three under par 285 as her compatriot Luna Sobron Galmes crashed to a 79 and joint fifth on one over.

Ballybunion's Emma O'Driscoll, third overnight, made an early birdie but then suffered in the tough conditions and posted a 78 to slip back to joint 11th on five over 293.

Irish Close champion Paula Grant of Lisburn looked on course for a top-10 finish but she dropped four shots in her last four holes, closing with a double bogey at the 18th, and came home 15th on seven over 295.

Royal County Down's Olivia Mehaffey was joint 26th on 14 over 302 after a 76 while Jean O'Driscoll missed the 54 hole cut.
