Australian Open 2019 Venue: Melbourne Park Dates: 14-27 January Coverage: Daily live commentaries on the BBC Sport website, listen to Tennis Breakfast daily from 07:00 GMT on BBC Radio 5 live sports extra and watch highlights on BBC TV and online from 19 January.

World number one Novak Djokovic reached the Australian Open third round with a straight-set win over Jo-Wilfried Tsonga.

The six-time champion in Melbourne beat the 33-year-old Frenchman 6-3 7-5 6-4.

Tsonga, whose ranking has fallen to 177 after a knee injury restricted him to 12 matches in 2018, showed flashes of his ability but the Serb, 31, was always in control.

Djokovic faces 19-year-old Canadian Denis Shapovalov, the 25th seed, next.

The match against Tsonga was a repeat of the 2008 final in Melbourne, which the Serb won in four sets to secure his first Grand Slam title.

"You could feel the tension on court at the beginning. We felt a lot of emotion and tried to play a great game," said Djokovic.

"It's always tough to play Jo. He has struggled with injury and his ranking doesn't do him justice in my eyes."
