Len Ikitau and Marika Koroibete scored two tries each as Australia secured a second successive victory over world champions South Africa in the Rugby Championship in Brisbane to regain the Nelson Mandela Plate.

Russia's Daniil Medvedev won his first Grand Slam tennis title, beating Novak Djokovic of Serbia 6-4 6-4 6-4 to win the US Open Men's Singles title at Flushing Meadows in New York.

In doing so, Medvedev denied Djokovic a calendar year clean sweep of the four biggest tournaments in the sport. The World No.1 had already won the Australian Open, French Open and Wimbledon titles this year. It's a feat that has not been completed by a male player since 1969.

Djokovic was also chasing a record 21st Grand Slam men's crown.
