GLEN COVE, N.Y. — Princess Mary Superal fired a two-under par 70 to stand four strokes off the pace after one round of the stroke-play qualifying in the US Women's Amateur on Monday (Tuesday, Manila time).
The 17-year-old Superal, who became the first Filipina to win a USGA event by topping last month's US Girls' Junior Championship, had two birdies and two bogeys at Nassau Country Club.
Superal, also the winner of the Southeast Asian Games gold in Myanmar last year, was tied for eighth with Grace Na and Angel Yin of the US and Celine Boutier of France.
Regina the Guzman, the other Filipina in the field, came up with a 72 and was in a big group in 22nd spot.
The top 64 after the second round Tuesday will advance to match play.
De Guzman hit three birdies, but also had three bogeys and a double bogey.
Australia's Su-Hyun Oh shot a 4-under 66 to take the first-round lead.
The 18-year-old Oh had six birdies and two bogeys.
"I'm playing quite solid," said Oh, a quarterfinalist last year at the Country Club of Charleston in South Carolina. "Just giving myself a lot of opportunities and making a few."
Eighth in the world amateur ranking, Oh matched the women's course record. She holed out from 40 feet for birdie from off the green on the par-4 11th.
"I thought, 'Just get it somewhere there,'" Oh said. "It felt good. I'll take it any day."
Sixteen-year-old Hannah O'Sullivan of Paradise Valley, Arizona, was a stroke back. She birdied four of her last six holes and needed only 25 putts.
"I just started hitting the ball better," O'Sullivan said. "I was putting great all day and just gave myself better opportunities and drained the putts."
Megan Khang, also 16, of Rockland, Massachusetts, opened with a 68.
Brooke Mackenzie Henderson, the 16-year-old Canadian who was the low amateur in the US Women's Open, shot 71.
Defending champion Emma Talley, the 20-year-old University of Alabama player from Princeton, Kentucky, was tied for 86th at 76.
Doris Chen, the NCAA champion for Southern California, withdrew after nine holes because of an ankle injury.
