SUNNINGDALE, England—Greg Norman shot a bogey-free 6-under 64 on Saturday 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 that left him six shots behind Norman. Television coverage begins at 1 p. m. today (Ch. 7).

Watson’s putter remained cold, despite an overnight grip change following similar problems Friday.

“I had five three-putts. I wasted a good ball-striking day,” he said. “I hit it very well and made absolutely nothing on the greens, although I did make a 60-footer [on the 13th hole] and a 30-footer [on the fifth].

“Otherwise, I was missing everything. Everything was right, everything pushed. Maybe I ought to aim left. I don’t have very good speed control on these greens.”

Norman found the right speed in a solid round.

“I put the ball in play and putted decently,” he said. “I got on the tee and could see the shots I wanted to play and just went and played them.”

The Shark loves the Sunningdale course, where he played often and won during his years on the European Tour.

“I feel comfortable around this golf course. I always have for some reason. I like the way it feels to me off the tee. You can be aggressive or conservative, depending on how you want to play. Today I had a mixture of both.”

Funk dropped his first shot of the week at the tough second hole, then double-bogeyed the 12th and bogeyed 14.

“The good news is that I’m still there. I can still win it,’ Funk said. “The bad news is that I put everyone else in the tournament right back in it.”
