Zheng Qinwen is the runner-up of last year's Australian Open, currently ranked fifth in the world women's singles, and the fifth seed in women's singles at this Australian Open.

Zheng Qinwen was warned by the chief judge twice today for overtime on serve, and she argued with the chief judge for a long time, complaining that she couldn't see the serve timer. Zheng Qinwen said frankly in an interview after the game, "The timer is on the side, so I can't see it at all when I serve, and I don't know if it will be timed out or too early." "When I was penalized for the second time, I was really surprised, and it obviously distracted me in the game. ”

Zheng Qinwen said that there were many opportunities to break Sigmund's serve in the first set, "but maybe I didn't concentrate enough at that time, and at the same time I thought she played very well, this is tennis, that's it." "Maybe today isn't my day." Zheng Qinwen said, "There are many details on the key score today, and the right choice was not made. ”

Zheng Qinwen has not played before the Australian Open this year after playing in the WTA Finals last year, and today's Australian Open is her second tournament in 2025. Zheng Qinwen said, "I didn't have the opportunity to play before this year's Australian Open because I had some physical problems that had not been resolved. ”
