NAPLES, Fla. -- Thanks to some nice shot-making on No. 17, Sandra Gal built a three-stroke lead on Friday in the CME Group Titleholders at Tiburon Golf Resort.
The former University of Florida golfer shot a 3-under-par 69 and is at 11 under after two rounds.
Sun Young Yoo is second after a second consecutive 68 that included three birdies in her first seven holes.
Gerina Piller had the best score of the day with a 5-under 67 that moved into contention at 6 under with Pornanong Phatlum and Cristie Kerr.
If Gal holds on to win the $700,000 first prize, she will double the money she has won this season.
With winds whipping to 20 mph, Gal said she chose to be more cautious than she was Thursday in the first round of the LPGA event.
Gal hooked her first shot into the woods on No. 17 but recovered nicely on the par-5 hole. After hitting her approach within 15 feet, she made a birdie putt.
Kerr overcame a double-bogey on No. 1 and a bogey on No. 3 with three straight birdies on Nos. 6-8. He had another birdie on No. 12 and an eagle on No. 17.
"I can make a lot of birdies and I snapped something into my head and I'm like, I'm swinging tentative at it," Kerr said. "On 17, I mean I was just due, I don't know how to describe it any other way than that."
Rolex Player of the Year Inbee Park made three birdies to go to 7 under, but she fell back with four bogeys on her final 10 holes and finished 36 holes at 4 under.
Teen-age pro Lydia Ko shot a 71 for the second day in a row. She's at 2 under.
"I thought I played much better today than yesterday, but the score was the same," Ko said.
Defending champion Na Yeon Choi is at 1 over after a 74.
Earlier in the day, the 2014 LPGA schedule came out. The tour will increase from 28 to 32 events and the purse will grow by more than $7 million.
The tour will begin with the Pure Silk Bahamas Classic on Jan. 23-26. New events will be in San Francisco on April 24-27; Sylvania, Ohio, on July 17-20 and Prattville, Ala., on Sept. 18-21. There's also an unnamed Asian event scheduled from Oct. 30 to Nov. 2.
Another new tournament is the International Crown in Owings Mills, Md., from July 24 to July 27. That event will feature team play among eight countries.
