Shocked by the news, in the just-concluded Australian Open women's singles second round, Zheng Qinwen lost 0-2 to Sigmund and was eliminated.

During the whole game, I felt that Zheng Qinwen was not in a state at all, and he couldn't play the relatively simple ball well. Don't know why?

Zheng Qinwen is ranked No. 5 in the world, the No. 5 seed at the Australian Open, and the runner-up at the Australian Open last year. The opponent is ranked 97th in the world. Zheng Qinwen is currently the highest-seeded player eliminated from the Australian Open, which is a big upset.
