PALM BEACH GARDENS, Fla. >> Jake Knapp survived a wild Saturday at the Cognizant Classic and avoided calamity at the troublesome par-3 15th by making a pair of late birdies for a 3-under 68 and a one-shot lead going into the final round at PGA National.

Knapp, who opened the tournament with a 59, started the third round with a one-shot lead and was trailing by three shots when he made the turn. He holed a 12-foot birdie putt on the 16th and finished with a chip-and-putt birdie on the par-5 closing hole to stay in front.

“A little bit all over the place,” said Knapp, who was at 16-under 197.

Right behind was Michael Kim — and nearly two dozen others.

There was so much movement in this captivating third round that 10 players had at least a share of the lead at one point. Some of them were undone by the 15th, playing 163 yards over water framed by a rock wall.

Taylor Montgomery, who had six birdies on the front nine and was the first player to reach 15 under, had a one-shot lead when he pumped two tee shots in the hazard on the 15th. The first was a line drive that nearly hit an alligator in the water. The second from the drop area rolled back into the crevice of a rock. It added up to a quadruple-bogey 7.

“You let your mind up in this game for one second, and it can bite you,” said Montgomery, who rallied with two birdies on the next three holes to salvage a 68. He was three behind.

Jesper Svensson of Sweden, who earned a PGA Tour card through the European tour last year, was tied for the lead when he caught too much ball from a bunker behind the 15th green and it sailed into the water. He made triple bogey, and hit his drive into the water on the 18th. Tied for the lead with four to play, he wound up six behind.

Another victim was Kim, though he had fortune on this side. He had a one-shot lead going to the 15th when his tee shot caromed high off the rocks, veered hard to the right and was headed for the water when it landed softly in the muck.

Most of the golf ball was showing, so he removed his right shoe and sock and blasted out of the mud and onto the green about 25 feet away. He two-putted for his first bogey of the tournament. It could have worse — and messier.

“I didn’t get as wet as I thought,” he said, though his face had speckles of mud.

Knapp made his mistakes on the front nine, particularly with his iron play and short game, but he steadied himself down the stretch as so many others struggled.

That leaves a final round loaded with possibilities on a course that has been getting firmer, particularly the green, as the week goes on under plenty of sunshine.

“It’s just a lot less pin hunting. It’s a little bit more conservative targets and you have to be a little bit more dialed in with distance control and shot shape and things like that because if you don’t you’ll end up in a bunker or water or somewhere you don’t want to be,” Knapp said.

Russell Henley and Ben Griffin each had a 66, and Doug Ghim had a 68 to finish the crazy day just two shots behind.

Ko takes third-round lead at LPGA Singapore

Lydia Ko shot a 4-under 68 Saturday to move from one stroke behind to one stroke in front after three rounds of the LPGA’s HSBC Women’s World Championship.

The 27-year-old South Korean-born New Zealander had a 54-hole total of 10-under 206 on the Tanjong course at Sentosa Golf Club.

Charley Hull, who birdied two of her first four holes, was a stroke behind in second after a 68. Jeeno Thitikul, who had four back-nine birdies for a 66, had the best round of the day to move into third place, three strokes behind Ko. A Lim Kim, who led after the first two rounds, moved in the wrong direction with a 73 and was tied for fourth place, four strokes off the lead. Defending champion Hannah Green had a 67 to move 16 places up the leaderboard and was five behind Ko.

Ko had three bogeys with seven birdies, including four on her back nine.

“I made a few mistakes but I was able to bounce back with a few good birdies as well,” said the former world No. 1. “It really doesn’t matter what the context is, as long as you can put a good score, and under the circumstances, I felt like I playing really solid. So hopefully these past few days will give me good rhythm for tomorrow.”

Ko is chasing her 23rd LPGA title and looking to finally break through in Singapore in 11 appearances. Her best result at the tournament was a runner-up finish in 2015.

Hull is seeking to win her third LPGA tournament.

“My mindset is going to be no different from literally the last three days,” Hull said. “Just go out there, play golf, hole some putts and have fun.”

Hull said she was looking forward to her final-round showdown with Ko.

“I like playing with Lydia, she’s a really, really nice person, so down-to-earth, so kind,” Hull said. “Just go out there, have a little chat and just play golf.”

The Singapore tournament is the second of three events on the LPGA’s first Asian swing of the year. The final event will be played next week at Hainan Island, China.
