Sabalenka chases number one ranking

Aryna Sabalenka said Tuesday that she wants to cap off a stellar year by returning to the top of the world rankings.

The world number two is the top seed at the China Open this week following the withdrawal of top-ranked Iga Swiatek, the defending champion, because of undisclosed "personal matters". Fresh from winning the US Open, Sabalenka can take a large step towards overhauling the Pole at the top of the rankings with victory in Beijing.

"Of course that's one of my goals, to finish the season at world number one," the Belarusian, who won the Australian Open at the start of the year for a second time, said.
