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