BEIJING (AP) — Second-ranked Aryna Sabalenka was bundled out in the third round of the China Open in straight sets by the Czech Republic's Nikola Bartunkova on Sunday.
The No. 34-ranked Bartunkova defeated the four-time Grand Slam champion 6-4, 6-3 in just over an hour and a half leaving the tournament without its two top seeds in the first week.
Newly-crowned world No. 1 Elena Rybakina was ousted from the tournament on Saturday and will now be joined by Sabalenka in exiting WTA-1000 event in Beijing early.
Sabalenka, who was denied a three-peat at the U.S. Open last month by Rybakina, squandered five break points in the first set as her historic struggles in Beijing continued. The 28-year-old Belorussian has never progressed past the quarterfinals at the event.
Bartunkova will next play 24-year-old Sinja Kraus of Austria, who earlier defeated Dayana Yastremska 6-1, 6-4.
In the men’s tournament, top seed and U.S. Open champion Alexander Zverev plays a quarterfinal match against Novak Djokovic later Sunday.
