SAN MARTIN, Calif. (AP) — Mirim Lee became the fifth golfer to shoot a round of 8-under par at the U.S. Women's Open when she made 10 birdies on the way to a 64 and the first-round lead.

Lee is the first woman to shoot that much below par at the U.S. Open since Lorie Kane and Becky Iverson did it in the second round in 1999 at Old Waverly in Mississippi. The lowest total score in a round in U.S. Open history is a 63 by Helen Alfredsson in 1994 at the par-71 Indianwood in Michigan.

Amy Yang birdied 18 to move into a three-way tie for second at -5 with Cristie Kerr and Minjee Lee.
