Charleston, SC (Sports Network) - Yumi Matsubara fired a tournament-record, 7- under-par 64 on Tuesday to grab stroke-play qualifying medalist honors at the U.S. Women's Amateur Championship.
After shooting even-par 71 in Monday's first round, the 14-year-old Matsubara charged to the top on Tuesday, eventually posting a two-day total of 7-under 135 at the Country Club of Charleston.
First-round leader Allisen Corpuz, a 15-year-old from Honolulu, shot 71 and ended the stroke-play portion of the event tied for second place at 2-under 140. She finished alongside Yueer Cindy Feng and Emma Talley, who shot 68 and 69, respectively.
Brittany Fan (69), Emily Tubert (70), Alison Lee (69), Brooke Mackenzie Henderson (70) and Kotone Hori (68) tied for fifth at 1-under-par 141.
There was a 5-for-4 playoff to determine the final match play spots, with Saki Iida, Bianca Maria Fabrizio, Lydia Choi and Laura Wearn making it through to Wednesday in extra holes.
Matsubara, of Japan, went bogey-free on Tuesday, carding seven birdies to break the previous 18-hole tournament record by a single stroke and grab medalist honors.
Last year's champion, Lydia Ko, and runner-up, Jaye Marie Green, both are not competing this week.
The match-play portion of the championship runs from Wednesday through Sunday's 36-hole final.
