Narin An leads with a 64 in the wind as Nelly Korda struggles in LPGA finale

NAPLES, Fla. — Narin An handled the windy conditions with a hot putter on Thursday, making four straight birdies around the turn and finishing with an 8-under 64 for a one-shot lead in the CME Group Tour Championship.

At stake for the 60-player field is a $4 million prize to the winner, the largest single-day payoff in women's golf.

Nelly Korda already has won more than that during her sterling season of seven wins. Now she faces an eight-shot deficit over the next three days at Tiburon Golf Club if she wants to end her year in fitting fashion.

Korda, coming off a victory last week, couldn't make amends for her three bogeys and had to settle for an even-par 72. She has come from behind in four of her victories, and still has 54 holes ahead of her. But it has made the task that much tougher.

Everything felt easy for An, a 28-year-old from South Korea who has never won on the LPGA and has never cracked the top 10 in any of the 16 majors she has played.

''Today my putt really good,'' An said. ''The speed was good and the shape was good. I just try to focus a little bit more.''

She had a one-shot lead over Angel Yin, who shot 30 on the back nine, including an eagle on the par-5 17th hole that most players can easily reach in two.

Former U.S. Women's Open champion Allisen Corpuz and Marina Alex were at 66, with Lydia Ko leading the group at 67.

Despite the wind so typical along the Gulf Coast of Florida, 27 players — nearly half the field — shot in the 60s.

''It's a good head start for the big ol' prize we get at the end of the week,'' Yin said.

Whoever wins this week is assured of breaking the 17-year-old LPGA record for most money earned in season. The record was set by Lorena Ochoa in 2007 at $4,364,994, back when the total prize money was about half of what it is now. Ochoa earned $1 million for winning the Tour Championship in 2007.

The opening round followed a big night of awards for the LPGA Tour, where Korda officially picked up her first award as player of the year, which she clinched earlier this month.

Ko was recognized for her big year, highlighted by an Olympic gold medal that put her into the LPGA Hall of Fame. She regained plenty of focus for the opening round on a course where she won just two years ago.

''The course isn't easy,'' Ko said. ''I set a goal of shooting 3 under today, and somebody shot 8 under. I was like, ‘OK, maybe I need to make a few more birdies.' It's a course that can get away from you as much as you can shoot some low scores, so I'm just trying to stick to my game plan and go from there.''

Also in the group at 67 was Albane Valenzuela of Switzerland, already celebrating a big year with her debut in the Solheim Cup and her first appearance in the Tour Championship.

She made a late run at her first LPGA title last week at Pelican Golf Club, and kept up her form. And she can see the finish line, which is appealing.

''I everyone is looking at that $4 million price tag,'' Valenzuela said. ''I try not to look too much at the result. I feel like in the past I've always been stuck on results, and ultimately all I can do is control my own round, my own energy, my own commitment.

''It's the last week of the year. It's kind of the bonus week. No matter what, everyone is having a paycheck.''
