NAPLES, Florida (AP) -- Lydia Ko didn't feel too many nerves in her pro debut on the U.S. LPGA Tour. It just took her awhile to make some birdies.

Ko overcame an early double bogey with three birdies on the back nine for a 1-under 71 in the LPGA Titleholders. The 16-year-old New Zealander already has won two tour events. She does not officially become a member until next year.

Sandra Gal birdied her opening six holes at Tiburon Golf Club, and rallied late with two more birdies for an 8-under 64. Gal had a one-shot lead over Rebecca Lee-Bentham.

Among those two back were Lexi Thompson and Anna Nordqvist, who can make more money ($700,000) by winning than she has all year. This is the largest payoff in women's golf.
