Irish golfer Damien McGrane hit a bogey-free round to earn a share of the lead after the first round of the Estoril Open today.
McGrane, the world number 220, picked up eight birdies - including three in a row between the 11th and 13th - to take the clubhouse lead.
Unfancied Englishman Luke Goddard birdied his last four holes to snatch a share of the lead.
Goddard, ranked 1,349 in the world, picked up shots at the sixth, seventh, eighth and ninth to join McGrane on an eight-under 64.
Goddard had earlier picked up four strokes on the back nine, with two birdies and an eagle two at the 11th at the Penha Longa Golf Club.
Dane Eirik Tage Johansen and Welshman Stuart Manley were one shot back after shooting 65s, Johansen collecting seven birdies and a bogey.
Manley enjoyed a more mixed round, with five birdies and eagles at the sixth and 12th marred by a pair of bogies.
