NEWPORT, Wales – Joost Luiten birdied seven of his last 10 holes to grab a one-shot lead in the first round of the Wales Open at Celtic Manor on Thursday.
Luiten parred his opening eight holes before storming up the leaderboard with a 6-under-par 65 on the Twenty-Ten course.
Of Europe's four Ryder Cup players in the field, Jamie Donaldson shot a quiet 1-under 70, Thomas Bjorn birdied the 18th to finish on par, Lee Westwood, who hasn't played in a month, bogeyed his last two holes to card a 2-over 73, and Stephen Gallacher failed to manage a birdie in a 7-over 78.
''I haven't played in three weeks, so there's a fair bit of rust in my game, but then I am thinking more about next week than this week,'' Gallacher said.
The Dutchman needed just 28 putts to match a similar score he shot on the opening day of last week's KLM Open, where he eventually finished in a tie for fifth.
''A 6-under-par start is always very good,'' he said. ''I holed some good putts and, looking back, I only missed one green all day, and had one bogey, and that was on 17.''
The Belgium-born Colsaerts, who played in the 2012 Ryder Cup, hit his tee shot 447 yards at the 575-yard, par-five 18th hole. That left him with a wedge to the green, and he walked off with an eagle three.
''The hole was playing downwind and I managed to get a good bounce. I thought it was too far right but there is a bit of a speed trap down the right side of the fairway, and it must just have luged it down there,'' he said.
Another stroke back at 4 under in a share of fourth place, were South Africa's Justin Walters and Englishmen Robert Rock and Sam Walker.
