Zaandvoort, Netherlands:Jean-Baptiste Gonnet and Taichi Teshima shot course record 6 under-par 64 to share the lead after the first round of the Dutch Open on Thursday.
France's Gonnet and Japan's Teshima enjoyed bogey-free rounds in calm conditions on the North Sea links at Kennemer Golf and Country Club.
Gonnet was coming off a runner-up finish at the Scandinavia Masters.
"Last week was very good and to follow that with a low round is very positive," Gonnet said. "But my goal is to get a victory and there is a long way to go."
Teshima hoped he would be more consistent than on previous occasions when he blew excellent starts.
"I shot 64 in Italy (at the Italian Open), eight under, but then followed up with a 77 and missed the cut by one," Teshima said.
Among the seven golfers a stroke behind were former US Open champion Michael Campbell, 2004 winner David Lynn, Sweden's Alexander Noren and Britain's Steve Webster.
Teenage newcomer Stefan Langer of Germany hit a 28-over 98, 31 strokes behind his father, Bernhard Langer. At 67, the three-time Dutch Open winner was three strokes behind Gonnet and Teshima. It was the first time a German father and son were playing in a European Tour event.
Defending champion Simon Dyson started with a 3-under 67.
