MELBOURNE, Australia — Novak Djokovic and Andy Murray have known each other for a quarter of a century. They played from the age of 12, meeting 36 times as professionals, including 10 Grand Slam matches. Yet they've never been able to talk shop and freely trade all sorts of thoughts — about tennis and otherwise — until now.

Novak Djokovic's former rival-turned-coach Andy Murray does not want the Serbian to suppress his emotions on court and is even willing to be the target of any angry outbursts as long as the 24-times major winner gives his all at the Australian Open.

Nick Kyrgios says he is good for tennis and the sport will get a boost from his return to Grand Slam action at the Australian Open.

Nick Kyrgios returns to the Australian Open and plays Britain’s Jacob Fearnley in his first match at the tournament in three years. The controversial Australian has been sidelined for most of the past two years following knee and wrist surgeries - and claims the sport has been “mundane” in his absence.

Nick Kyrgios has hailed the ‘X factor’ of rising British tennis star Jacob Fearnley ahead of their first-round showdown at the Australian Open. Fearnley, 23, is set to feature in his second Grand Slam main draw having impressively pushed Novak Djokovic to four sets at Wimbledon last year.

Iga Swiatek, a self-described “control freak,” is taking new precautions — including holding on to extra samples of medicine she takes, in case they need to be tested at some point — after a doping case she describes as probably the worst time in her life.

Jannik Sinner and Iga Swiatek were both able to go for months last season without anyone knowing what was happening behind the scenes and that they'd failed doping tests.

Iga Swiatek says that her positive doping test was abstract to her as she did not know that medicine could be contaminated.
