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.

Russell Henley and Ben Griffin each had a 66.

Twenty-two players were within five shots of the lead, a group that includes Jordan Spieth (68) and Brian Campbell, who won his first PGA Tour title last week in Mexico and shot 66.

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.”
