The two leaders both started and finished their rounds. Lorena Ochoa was just a little stronger.
Ochoa, the No. 1 player in the world and the defending tournament champion, gained a one-stroke lead Saturday at the LPGA Safeway International, shooting a 3-under par 68 at Superstition Mountain Golf and Country Club near Gold Canyon.
Angela Stanford opened the day with a one-stroke lead and shot a 69. She is tied for second with Jee Young Lee, who fired a 67. Because Lee finished her round first on Saturday, she will be paired with Ochoa in the final group today, which will tee off at 12:41 p.m.
Stanford and Ochoa, playing in the last group Saturday, each opened with birdies on the first two holes. Ochoa then birdied the fourth to tie Stanford atop the leaderboard, and after hitting an 8-iron to within 25 feet, Ochoa birdied the par-4 fifth hole to take the lead.
Ochoa and Stanford both birdied the 18th hole.
Saturday is often called moving day in golf, and two players named Park made their moves with third-round 65s.
Inbee Park is tied for fourth at 12 under, while Grace Park, an Arizona State alumnus, is tied for 20th. She was among the last group of players to make the cut.
Annika Sorenstam shot a 1-under 71 on Saturday and fell into a tie for eighth.
