595th-ranked Zhang stuns US Open semi-finalist Navarro in Beijing

The 35-year-old Zhang reached round three of the China Open, where she is the lowest-ranked player to ever compete in the main draw of her home tournament.

On Wednesday, Zhang won her first singles match since January 2023 to snap a painful run of 24 defeats on the WTA Tour.

Coming into the prestigious WTA 1000 event as a wildcard, the former top-25 player defeated the 65th-ranked American McCartney Kessler in straight sets.

Zhang, a two-time Grand Slam quarter-finalist who has been plagued by injuries, repeated the feat with a surprise victory over the American sixth seed Navarro.

Zhang, who has won two Grand Slam doubles titles, faces the 28th-seeded Russian Anastasia Potapova or Belgium's Greet Minnen next.
