England's Robert Dinwiddie made a flying start to lead the KLM Open during the early stages of the first round.
The Challenge Tour graduate birdied the ninth, then picked up more strokes at the tenth, 12th, 16th and 18th to be five under and one clear of compatriot Simon Dyson.
The English were certainly making their presence felt with Robert Coles, Oliver Wilson and Seve Benson in the group tied for third on two under, alongside Italy’s Edoardo Molinari, German Marcel Siem and Dane Anders Hansen.
Defending champion Martin Kaymer, though, bogeyed the short tenth to be one over.
Lee Westwood and Rory McIlroy were among the later starters.
Earlier vandals who attacked several of the greens delayed the start at Hilversum in The Netherlands.
Areas on the fourth, fifth, sixth and ninth were dug up overnight, leading to a 45-minute hold-up to the first round as the damage was repaired.
The affected parts were marked off as ground under repair, allowing players to move balls away when necessary.
Championship Director Daan Slooter said: "At this moment we do not know who caused the damage. For this evening and the rest of the tournament we have increased security substantially.
"I'm very disappointed for all the people here at the club who worked so hard over the past few days, through challenging weather conditions, to ensure the course was in playable condition.
"However, having said that, the same professionalism of the greenkeepers has ensured that the damage has been repaired so the tournament can go ahead. They are all due a huge vote of thanks."
