Nicolas Colsaerts has taken a three-shot lead at the Portugal Masters after carding a first-round 60 in rainy Vilamoura.
Play was suspended with a number of golfers in the field yet to finish their rounds, but Colsaerts came through his 18 in impressive fashion by making seven birdies and two eagles.
The Belgian was close to recording the European Tour's first round of 59, but it was not to be as he failed to putt a long-range attempt on the 18th.
Scott Jamieson and Alexander Levy are the closest to challenging after they both went round in eight-under 63s.
Europe's successful Ryder Cup captain Paul McGinley had a blemish-free round with four birdies to finish on four-under par.
Darren Clarke, who is being tipped to lead the next the team in two years time, was 10 shots off the pace when play was suspended with two holes left for him to play.
