Novak Djokovic apologised for almost hitting a ball girl in an act that could have put his Australian Open hopes in jeopardy.
The 24-time grand slam champion made more history at Melbourne Park, with his 6-3 6-4 7-6 (4) victory over Botic van de Zandschulp making him the first player ever to record 400 singles wins at the grand slams, while his 102nd triumph in Australia equalled Roger Federer's mark.
