Joost Luiten carded a 5-under 65 on Thursday and grabbed a share of the lead with the first round of the KLM Open suspended due to darkness.
Luiten was joined at minus-5 by Jamie McLeary, who completed 16 holes of round one at Kennemer Golf & Country Club.
Italians Edoardo Molinari and Andrea Pavan posted 4-under 66s. They share third place with Gary Stal.
Thomas Aiken, Daniel Im, Tano Goya, Maximilian Kieffer and Andy Sullivan are tied for sixth at minus-3. Paul Casey and Matteo Manassero headline a group of players at 2-under par.
There was a delay of nearly two hours after Fabrizio Zanotti was struck in the head by a wayward tee shot. Alexandre Kaleka hit a poor tee shot off the 14th tee and hit Zanotti in the forehead as he played the 16th.
Zanotti was treated on the course, then taken to a hospital for further testing. He was later released.
