Change at the top

Graham Marsh birdied the par-4 eighth hole just moments before Tom Purtzer took a bogey on the par-3 seventh, meaning the two swapped spots.

Marsh is now in the lead at 6 under, while Purtzer dropped into second at 5 under.

Mark McNulty, Jay Haas, R.W. Eaks and John Cook are currently tied for third, another stroke back.
