Ogilvy's 63 has him in front in Melbourne

Geoff Ogilvy cruised to an eight- par 63 on Saturday and has a two-shot lead at 13-under par heading to the final round of the JBWere Masters.

Ogilvy, the 2006 U.S. Open champion, shot up the leaderboard with an eagle on the first hole and birdies on the next two to fly past second-round leader Ian Poulter.

Poulter held a two-shot lead coming into the third round, but only managed a two-under 69 and sits alone in second at two shots back.

Nathan Green (67) and Ashley Hall (68) are four shots back at nine-under, while five players share fifth at seven-under par, including Greg Chalmers, who is trying for the Australian Triple Crown after capturing the Australian Open and Australian PGA Championship. Chalmers shot a 67 on Saturday.

World No. 1 Luke Donald carded a two-under 69 and trails Ogilvy by eight shots at five-under par.
