Greg Norman shot a bogey-free 6-under 64 on Saturday in Sunningdale, England, to grab the lead by a stroke heading into the last round of the Senior British Open.

Norman was at 10-under 200, a stroke ahead of overnight leader Fred Funk (72) and Loren Roberts (67).

Tom Watson's hopes of improving on his runner-up spot in the British Open last week took a hit after a 70 left him six shots behind Norman.

Larry Mize also shot a 64, and Bernhard Langer, Ben Crenshaw and defending champion Bruce Vaughan all had 65s. Langer has a share of seventh place, four shots behind Norman as he bids for his fifth Champions Tour victory of the year.

Jason Dufner flirted with a 59, then settled for a 9-under 63. Mark Calcavecchia made a PGA Tour-record nine straight birdies. And there were two more aces in perfect scoring conditions at the Canadian Open in Oakville, Ontario.

The fun didn't last long, giving way to 1.8 inches of rain on the already-saturated Glen Abbey course. Soon after Dufner finished the second round in light showers, the heavy rain forced tour officials to postpone the third round until this morning.

In an attempt to get 36 holes in today, the tour cut to the low 60 and ties instead of the usual low 70 and ties, leaving 64 players in the tournament.

At 13 under, Dufner had a one-stroke advantage over Jerry Kelly (67) and 2001 winner Scott Verplank (67).

Becky Brewerton of Wales shot a 3-under 69 to grab a share of the Evian Masters lead for the third consecutive round in Evian-les-Bains, France.

Brewerton heads into today's final round tied with Sophie Gustafson of Sweden -- who had a 5-under 67 on Saturday -- and In-Kyung Kim of South Korea at 12-under 204.

Ai Miyazato of Japan, the joint second-round leader with Brewerton and Na Yeon Choi of South Korea, bogeyed the final hole to drop a shot back at 205. She was joined by Cristie Kerr, who made a birdie on No. 18 for a 67.
