LOCH LOMOND, Scotland, July 9 (Reuters) - Motor racing fan Richard Green was quick off the Scottish Open grid before accelerating into the lead with a seven-under-par 64 in Thursday's first round.

The Australian left-hander, who says he enjoys nothing more than driving and maintaining his own race car, reeled off six birdies and an eagle on a day of glorious sunshine to leave a top-class field trailing.

Sharing second place on 65 were British pair Graeme Storm and Martin Laird, Ireland's Paul McGinley and Gonzalo Fernandez-Castano of Spain who squeezed nine threes into his round.

"It was a great round of golf ... (I was) very much under control," Green told reporters at the warmup event for next week's British Open at Turnberry.

"I love this place. I remember the first time I came here in 1996, I finished joint sixth. Today was very easy for us and it seemed very easy for me."
