Naples, Florida - Japan's Ai Miyazato collected nine birdies in an eight-under par 64 on Friday to take a one-shot lead midway through the LPGA tour's season-ending Titleholders tournament.
Miyazato, seeking a third victory this season, had just one blemish on her card, a bogey at the par-five second hole.
She more than atoned, with five birdies on the front nine and four more on the back at TwinEagles for a 10-under total of 134
after two rounds.
She was one shot in front of South Korean Na Yeon Choi, the US Women's Open champion who carded a 68 for 135.
South Korea's Sun Young Yoo, part of a trio sharing the first-round lead, was two shots adrift until she was assessed a one-shot penalty for an improper drop.
That gave Yoo a one-under 71 and put her in a tie for third on 137 alongside France's Karine Icher (70), American Brittany Lincicome (69) and overnight co-leader Suzann Pettersen of Norway (71). - Sapa-AFP
