CASCAIS, Portugal (AP) - Pablo Martin-Benavides became the first amateur to win the Estoril Open after shooting a 3-under 68 on Sunday.

The 20-year-old Spaniard had three birdies on the Quinta da Marinha Oitavos Golf Club course to finish the tournament at 7-under 277, one stroke ahead of Raphael Jacquelin (67).

Jacquelin had six birdies and two bogeys and will receive the prize money because of Martin- Benavides' amateur status.

David Griffiths (68) shared third with Graeme Storm (72), Martin Kaymer (67) and Charl Schwartzel (69) at 281.

Defending champion Paul Broadhurst (74) double-bogeyed the 11th hole and had two birdies and three bogeys to finish in a tie for 54th at 5-over 289.
