PHOENIX — Ai Miyazato birdied three consecutive holes on the back nine and shot 6-under 66 for a share of the LPGA Founders Cup lead with Yani Tseng on Saturday.
Miyazato, a Japanese player with seven tour victories, birdied Nos. 14-16 and closed with two pars for a bogey-free round in partly cloudy, breezy conditions to stand at 14-under 202.
"It was more difficult than (Friday)," Miyazato said. "The wind makes more greens firmer, and I did (hit) a long distance because some holes were really downwind. It was difficult to make birdies out there. But I was really patient, and my putting was really good."
The weather is expected to be a factor for today's final round. Temperatures are forecast to be in the 50s with rain and strong winds possible.
"It could be you need to make some birdies out there. But then you need to be really patient out there, too," Miyazato said. "But it doesn't matter about the weather."
Tseng, the second-round leader from Taiwan who has 13 tour victories, had a chance to take the lead at the par-4 18th. She hit to 10 feet out of a fairway bunker. But her birdie putt rolled just past the left edge, and she settled for 67.
"I was a little disappointed out there," Tseng said. "I played so good. I hit lots of good drives and hit lots of good shots, and I missed three short birdie putts."
Na Yeon Choi (67) was a stroke back and fellow South Korean I.K. Kim (69) three back. Tampa resident Kristy McPherson (72) sat tied for 20th, eight back.
Champions: Mark Calcavecchia shot his second 4-under 67 in rainy conditions to take a two-stroke lead at the Toshiba Classic in Newport Beach, Calif. He had six birdies and two bogeys to sit at 8-under 134. Fred Couples (69), the 2010 winner of the event, and Loren Roberts (70) sat one back.
