Against serbia

Zheng Qinwen: Battling greater expectations, illness and a slew of top players, rising Chinese tennis star Zheng Qinwen weathered a torrid season-opening United Cup mixed teams competition by calmly focusing on "becoming the best version of myself".

At a career-high world ranking of 14, Zheng is China's top-ranked women's singles player after a breakout season last year. The 21-year-old lived up to the hype in the mixed teams United Cup in Perth when she stunned Wimbledon champion and world No. 7 Marketa Vondrousova 6-1, 2-6, 6-1 in her opener.

The upset inspired China to an impressive sweep over the highly fancied Czech Republic to kick-start their quarterfinal run, reports Xinhua.
