Story summary

Aryna Sabalenka, ranked second globally, was unexpectedly defeated in straight sets by Nikola Bartunkova from the Czech Republic at the China Open tennis tournament in Beijing. The match lasted just over an hour and a half with Bartunkova winning 6-4, 6-3. This defeat came after Sabalenka's recent loss to Elena Rybakina at the U.S. Open, preventing her from achieving a threepeat. Sabalenka had previously struggled in Beijing, never advancing past the quarterfinals. Meanwhile, newly crowned world No. 1 Elena Rybakina was also eliminated earlier in the tournament, leaving both top seeds out of contention early on. Bartunkova credited her own focus and respect for Sabalenka as reasons for her victory, while looking ahead to facing Austria's Sinja Kraus next.
