Four Advance to Semifinals in U.S. Women's Amateur

Lauren Diaz-Yi, a 17-year-old from Thousand Oaks, Calif., who defeated medalist Yumi Matsubara of Japan in the second round of match play, lost 4 and 3 to Doris Chen of Chinese Taipei on Friday to fall out of the U.S. Women's Amateur at the Country Club of Charleston in South Carolina

In June at the U.S. Women's Public Links, Diaz-Yi routed Chen 10 and 9.

In Saturday's semifinals, Chen will face Yueer Cindy Feng of Orlando, who had an easier time of it in beating Annie Park of Levittown, N.Y., by a 6-and-4 margin.

Park won the NCAA individual title this year as a freshman at Southern California, which won the 2013 team championship as well. Chen is also part of the Trojan women's golf team.

Alison Lee of Valencia, Calif., beat Katelyn Sepmoree of Tyler, Texas, 4 and 3, and will square off against Emma Talley of Princeton, Ky., who needed 19 holes to defeat Su-Hyun Oh of Australia.
