Harukyo Nomura moved up to a share of fourth place at the U.S. Women's Open on Friday after shooting a 3-under 69 in the second round to stay three strokes off the pace.

Starting the day in 11th, Nomura carded four birdies and one bogey at the par-72 CordeValle for a 5-under 139 total in the third major of the season.

Park Sung-hyun had a 66 to top the leaderboard with a 136, while fellow South Koreans Amy Yang and Mirim Lee were another two strokes back in a tie for second.

With two wins this campaign and eyeing her first victory in a major, Nomura bogeyed the fourth, but rebounded with a birdie on No. 9 and added three more after the turn.

"The wind was really strong so I'm more than satisfied (with the score)," Nomura said. "I think it's the same with everyone but I'm here because I want to win. If I can concentrate on my game, I should come up with a good result."

Ayaka Watanabe sits in 29th with a 1-over 145, while Sakura Yokomine and Erina Hara also advanced to the final rounds after placing 38th and 60th, respectively.

Mika Miyazato missed the cut by a stroke after a 6-over 78.
