PORTLAND, Oregon — Angel Yin shot a 5-under 67 on Tuesday (Wednesday, Manila time) to share medalist honors with Jennifer Hahn in the US Women's Amateur.
Princess Superal, the US Girls Junior champion last year, fell short of the Match Play, however, adding a 78 to her opening 75.
One of nine USGA champions in the field, Superal left herself some catching up to do after the slow start, then had a rollercoaster second round that featured two birdies, six bogeys and a double-bogey at Portland Golf Club.
Playoffs were still to be played to determine the who will make it to the final places in the top 64, who will battle it out in Match Play.
Daniella Uy also did not make it to the next phase after a second-straight 77.
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 US Girls' Junior final in Tulsa, Oklahoma.
"Confidence. Maybe momentum," Yin said. "I didn't play golf for three days after I went back home (from the Girls' Junior), so I took a break, which is good."
The 21-year Hahn, from Henderson, Nevada, had a 70. She'll be a senior at Vanderbilt.
"Staying patient was a big factor," Hahn said. "Ball-striking wasn't as good as yesterday. I was kind of crooked off the tee, found myself in the rough a lot, hitting punch shots, but I gave myself the best chances to save or get up and down for par."
Nelly Korda of Bradenton, Florida, broke the women's course record with a 66 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, but dropped strokes on her 16th and 17th holes.
"It was amazing," Korda said. "I've never been 8 under par, the lowest score (I've ever) shot was 7 under. To come one short of it is kind of a little sad, but I'm happy with how I played."
Petr Korda caddied for his daughter.
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 US 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.
