MELBOURNE (Reuters) - Novak Djokovic got his Australian Open title defence off to a rollicking start, breezing past Frenchman Jeremy Chardy 6-3 6-1 6-2 on Rod Laver Arena on Monday.
The world number one, who has won eight of his 17 major titles at Melbourne Park, rattled off 41 winners and did not face a single break point en route to victory.
Serena Williams kickstarted her bid for a record-equalling 24th Grand Slam title with a 6-1 6-1 drubbing of Germany's Laura Siegemund before rushing off the court to watch Tom Brady win his seventh Super Bowl.
Nick Kyrgios treated the sparse crowd at the John Cain Arena to some vintage moments -- a racket thrown across the court, and a few choice words towards his box and the umpire -- as he sailed to a 6-4 6-4 6-4 victory over qualifier Frederico Ferreira Silva.
Bianca Andreescu was made to work hard on her return to competition after 15 months, but the 2019 U.S. Open winner dug deep to see off Mihaela Buzarnescu of Romania 6-2 4-6 6-3.
Alexander Zverev overcame an inconsistent start and a smashed racket to battle past unheralded American Marcos Giron 6-7(8) 7-6(5) 6-3 6-2, while U.S. Open champion Dominic Thiem fended off Mikhail Kukushkin 7-6(2) 6-2 6-3.

The championships were delayed by three weeks to allow all players arriving from abroad to quarantine for two weeks.
