Sabalenka beats Keys to reach Beijing quarters
The three-time Grand Slam champion has won 46 of her 57 singles matches in 2024.
Sabalenka claimed the Cincinnati Open and the US Open during her current unbeaten run.
The Belarusian can put pressure on world number one Iga Swiatek, who has skipped the China Open due to personal matters, if she goes all the way in Beijing.
