MELBOURNE - China's Gao Xinyu and Wei Sijia are one step closer to reaching the main draw at the Australian Open after winning their opening qualifying matches on Tuesday.

Gao continued her form from the United Cup, where she helped team China reach the quarterfinals, with a dominant 6-0, 6-0 win against Anouk Koevermans of the Netherlands in 63 minutes at Melbourne Park.

The Chinese 27-year-old, who rose in the rankings from 175 to a career-high 146 following the United Cup, equaled Koevermans' 10 winners for the match but hit only seven unforced errors compared to her opponent's 32.

In other matches, China's Zhu Lin was defeated 6-3, 1-6, 6-2 by France's Selena Janicijevic, while China's Shi Han went down against Jil Teichmann 5-7, 6-2, 6-2.
