Miyazato birdied the closing hole at the Ko-Olina Golf Club as the winds that had abated during the second round Thursday returned.
Cristie Kerr moved into a tie for second at 209 with Azahara Munoz, who began the day tied for the lead with Miyazato but who had to settle for a 1-over 73.
Miyazato successfully battled the winds to make the turn in 1-under, but she bogeyed both the par-3 holes on the back side to mar an otherwise excellent round.
