Jordan Spieth had a performance that matched the magnificent views — finally — in Pebble Beach. Calif., on Saturday.

Spieth took only 10 putts on the back nine, closed with a pitch that checked up inches from the cup for another birdie and shot a 7-under-par 65 to open a six-shot lead going in the final round of the AT&T Pebble Beach Pro-Am.

Starting out the weather-delayed event tied with Jason Day and Derek Fathauer, Spieth never gave anyone a chance.

Following his only bogey of the round — a 7-iron over the cliffs on No. 8 that narrowly stayed up in the rough above the putting surface — he ran off three straight birdies, made a tough, curling 6-foot par putt on the 12th, and then closed with three birdies and another tough par save on his last four holes.

He was at 17-under 197 and had his largest 54-hole lead on the PGA Tour.

Brandt Snedeker did his part with a 30 on the front nine — he started on No. 10 — for a 67 to pull within two shots when he finished. Spieth was up the hill on the 14th, doing what Spieth does — a 6-foot par save.

‘‘Those putts scare me,’’ Spieth said after making a downhill 3-footer for par on No. 4.

But he made them all, except for the 8-foot par putt on No. 8 that he missed immediately, pausing when a heel print nearly kicked the ball left and into the cup.

Snedeker, trying to win at Pebble Beach for the third time in five years, was at 11-under 204 and will be in the final group with Spieth, along with their amateur partners. Spieth is playing with country singer Jake Owen, while Snedeker’s partner is Nashville businessman Toby Wilt.

‘‘Jordan is going to be out outnumbered,’’ Snedeker said. ‘‘We got three Tennesseans in that group, so it will be a lot of fun to get in there. But the front nine will be huge tomorrow, the first seven holes. I've got to go out there and make some birdies and put some pressure on him.’’

Dustin Johnson spent three days with Spieth and couldn’t keep up, at least not on the greens. The US Open champion made three birdies over his last six holes and saved par from a shot into the Pacific Ocean on No. 18 for a 66. He was seven shots behind.

There were questions whether Johnson’s second shot ever cleared the hazard along the ocean wall. A television replay was not entirely conclusive.

European and Asian — Masters champion Danny Willett shot a 5-under 67 at the Maybank Championship to finish the day three strokes ahead of David Lipsky heading into Sunday’s final round in Kuala Lumpur, Malaysia.

Champions — Fred Couples birdied the final two holes to pull within a stroke of the leaders at the Allianz Championship in Boca Raton, Fla.. Couples shot a 7-under 65 to reach 11-under 133 on The Old Course at Broken Sound. Doug Garwood, Joe Durant, Scott McCarron, and first-round leader Olin Browne shared the top spot.

Ladies European — Melissa Reid of England shot a 6-under 67 to take a two-stroke lead over American Angel Jin and Australian Su Oh at the Vic Open in Barwon Heads, Australia.
