Angel Yin shot a 5-under 67 on Tuesday to share medalist honors with Jennifer Hahn in the U.S. Women's Amateur at Portland Golf Club.
The 16-year-old Yin, from Arcadia, California, had seven birdies and two bogeys to match Hahn at 6-under 138. Yin lost to Eun Jeong Seong last month in the U.S. Girls' Junior final in Tulsa, Oklahoma.
The 21-year Hahn, from Henderson, Nevada, had a 70. She'll be a senior at Vanderbilt.
Yin and Hahn topped the 64 qualifiers for match play.
Nelly Korda of Bradenton, Florida, shot a 66 — the best round of the week — to tie for third with Australia's Hannah Green at 5 under. The 17-year-old Korda, sister of LPGA Tour player Jessica Korda and daughter of former tennis player Petr Korda, birdied eight of the first 14 holes.
The 18-year-old Green had a 68.
Defending champion Kristen Gillman, 17, of Austin, Texas, tied for ninth at 2 under after a 71.
The 15-year-old Seong, from South Korea, tied for 22nd at even par after a 70.
Ellen Port, the oldest player in the field at 53, failed to qualify. The 2014 U.S. Curtis Cup captain, from St. Louis, followed her opening 77 with a 72. The youngest, 14-year-old Anne Chen of Sugar Land, Texas, also dropped out. She shot 82-78.
