World number one Aryna Sabalenka said she felt “refreshed and ready to go” for the new tennis season while looking to build on her stellar year.
The Belarusian defended his Australian Open title in January before winning the US Open in September – his third major singles title.
He also replaced Iga Swiatek at the top of the world rankings and finished as number one at the end of the year.
The 26-year-old will open his season at the Brisbane International, which starts on December 29.
“There are a lot of things that need to be improved,” Sabalenka said.
“I wasn’t very good in my singles game at the net. There is a lot to improve in my touch game.
“Even my serve is not as good as I would like, so there are always (elements) that need to be improved.”
