Graeme Storm of England shot a course record 7-under 63 to lead the KLM Open by two shots in the opening round on Thursday.

Storm birdied three of his closing four holes on the Hilversumsche course. His effort was three shots fewer than his previous best score in the premier Dutch event.

"I made the birdies when I gave myself the chances, and I managed to get up and down when I missed the greens," he said.

Storm teed up in the Netherlands ranked 353rd in the world. He wants to end the season inside the top 115 to retain full European Tour membership next season.

Martin Kaymer, Frenchman Raphael Jacquelin and Paraguay's Fabrizio Zanotti also surpassed the previous course record with their 5-under 65s to tie for second place.

Kaymer, who won the KLM Open two years ago, capped his round with an eagle at the 12th where he holed a 20-foot putt. Europe teammate Peter Hanson of Sweden also produced a 68 in his last event before the Ryder Cup.
