Taipei, Jan. 25 (CNA) Chuang Chia-jung became the last Taiwan player standing in the senior level competition of the 2010 Australian Tennis Open when she and Slovakia's Filip Polasek made the mixed doubles quarterfinal after an upset win over the third-seeded U.S. pair Berthanie Mattak-Sands and Bob Bryan Monday.
Chuang and Polasek prevailed 7-5, 7-6 (7-4) in tough battle on Melbourne's Show Court 3, the same court on which Taiwan's Chan Yung-jan was knocked out of the women's doubles two hours earlier.
Chan and her Romanian partner Monica Niculescu lost 7-5, 6-3 to Lisa Raymond (USA) and Rennae Stubbs (AUS) in the third round of the women's doubles.
On Sunday, Hsieh Su-wei, who paired with China's Peng Shuai, also lost in the third round of the women's doubles, a category in which Taiwan players have had relative success in recent years.
Local fans will be looking to the juniors to keep Taiwan in play for the remainder of the competition as Huang Liang-chi and Juan Ting-fei are still going in the boys' singles and doubles and girls' singles.
Huang and Japan's fourth seeded Yasutaka Uchiyama beat Vaidik Munshaw (IND) and China's Wang Chunan 6-2, 7-6 (7-3) Monday in the junior boys' doubles first round.
Juan Ting-fei and China's Liu Min did not have a good day, as they were crushed by the third seed Tamara Curovic (SRB) and Sachie Ishizu (JPN) 6-0, 6-1 in the girls' doubles first round.
Huang, the fourth seed in the boys' singles, is scheduled to meet Australian James Duckworth in the boys' singles second round Tuesday, while Juan will meet fifth-seeded Silvia Njiric of Croatia in the girls' singles second round.
The Taiwanese players in the singles competitions didn't last long, as Lu Yen-hsun, Chan Yung-jan and Chang Kai-chen all crashed out early in the men's and women's singles.
Lu, Taiwan's top men's player who currently ranks No. 101 in the ATP men's tour, had a disappointing early exit when he lost to Louk Sorensen of Ireland 6-4, 3-6, 6-2, 6-2 in the first round.
Lu reached the third round in Melbourne last year, his best finish in a grand slam tournament, but this year failed to make it past the first round in the men's doubles as well.
Chan Yung-jan and Chang Kai-chen, currently ranked 85th and 94th in the WTA Tour respectively, both lost in the first round singles to higher-ranked players.
