Kyrgios fit and raring to go

The 19-year-old did not play in this week's Hopman Cup because of the injury, but is expected to play at Olympic Park in the Sydney International starting on Sunday.

Kyrgio had a 45-munite workout at the Olympics Park arena on Thursday and tweeted that all was fine with his fitness.

"Good hit out on #RosewallArena @SydneyTennis," he tweeted.

"Felt good and looking forward to cracking on with the Aussie Summer."
