Just six months after the birth of her daughter Bella, Switzerland's Tokyo 2020 Olympic gold medallist is returning to the WTA Tour.

The world No. 9, who has been off the court since September, had planned to end her career this season in order to start a family.

Dimitrov, Gauff, and Rublev picked up where they left off, while Rybakina and de Minaur came out with guns blazing.

Zverev beat Hubert Hurkacz in a three-set thriller before teaming with Laura Siegemund to win the mixed doubles in a deciding match tiebreak.

De Minaur will become the first Aussie man in 18 years to break into the ATP's Top 10 rankings come Monday as a result.
