Canadian teen Brooke Mackenzie Henderson advanced to the U.S. Women's Amateur quarterfinals Thursday, winning two matches at Nassau Country Club.

The 16-year-old Henderson, the low amateur in the U.S. Women's Open, beat Ember Schuldt of Sterling, Illinois 4 and 3 in the morning, and topped Dylan Kim of Plano, Texas, 3 and 2 in the third round.

Henderson, the Smith Falls, Ontario, player who is second in the world amateur ranking, is trying to become the first Canadian winner since Cathy Sherk in 1978.

Henderson will face Alison Lee of Valencia, California, on Friday. Lee edged Eimi Koga of Honolulu in 20 holes in the third round.

In the other upper-bracket quarterfinal, Hannah O'Sullivan of Paradise Valley, Arizona, will play Grace Na of Alameda, California. In the third round, O'Sullivan edged Canada's Augusta James in 20 holes, and Na beat Lauren Kim of Los Altos, California, 2 up.

In the lower bracket, Australia's Su-Hyun Oh will play Kristen Gillman of Austin, Texas; and Andrea Lee of Hermosa Beach, California, will face South Korea's Eunjeong Seong.

In the third round, Oh routed defending champion Emma Talley of Princeton, Kentucky, 9 and 8; Gillman beat Casey Danielson of Osceola, Wisconsin, 5 and 3; Andrea Lee topped Jessica Porvasnik of Hinckley, Ohio, 4 and 2; and Seong beat New Zealand's Liv Cheng in 19 holes.
