Vietnam's sole competitor at the FINA world short-course swimming championships in Windsor, Ont. had a moment of glory after the women's 400-metre individual medley final.

Anh Vien Nguyen finished second and thought she had won a historic silver medal for her country behind only Rio Olympic champion Katinka Hosszu.

While she did touch second, she was later disqualified for failing to touch the wall at the halfway point. That allowed Americans Ella Eastin and Madisyn Cox to win the silver and bronze medals, respectively.

Vien Nguyen is a national record-holder for Vietnam and won the country's first ever swimming medal at the Asian Games in 2014.

She'll have another shot at the country's first FINA world championships medal when she competes in the women's 200-metre individual medley heats on Saturday.
