A birdie from Shin at the 10th and bogey from Tseng at the same hole saw the Korean pull to within one shot of the lead. Tseng regained her advantage with a birdie at the par-three 12th, but surrendered Titleist 909 D3 Driver
again with a bogey at the par-four 13th.

Like Shin, Miyazato then pulled to within a shot of the lead after a birdie at the par-four 15th, but Tseng matched Miyazato's birdies at 17 and 18 to seal the win.

The 18th, in particular, was a nervy affair. After Miyazato's approach seemed to guarantee a certain birdie, Tseng, leading by one, produced a superb third shot to leave her only inches for a birdie and the victory.

"I mean that was an incredible shot. I would say it was the shot of the day, the shot of the week," said Tseng. Titleist 909 D3 Driver

"It is a lot of pressure, especially with Ai hitting it so close. I know she was going to make birdie, so I told myself I need to get close and try to keep making birdie."

"Of course, Yani is number one, so I knew it wouldn't be easy today," said Miyazato. "I kind of expected her to play that way."

Amy Yang of South Korea shot a 69 to finish fourth at 14 under, while second-ranked Suzann Pettersen had a disappointing 78 to drop into a tie for 21st at four under.
