Joking aside, No. 1 Djokovic hopes to make history Print article Send a Tip AP 1/13/2013 8:27:40 AM (AP) Joking aside, No. 1 Djokovic hopes to make historyBy JOHN PYEAP Sports WriterMELBOURNE, AustraliaNovak Djokovic shelved the conventional preparations for a while, warming up for a shot at a third consecutive Australian title with a bit of weekend hit-and-giggle and a Gangnam Style dance with Serena Williams.That was for kids' day, when thousands of people flocked to Rod Laver Arena to see 2012 Australian champions Djokovic and Victoria Azarenka hitting in a just-for-fun match with players including past champions Roger Federer and Williams, a cast of human-sized cartoon characters and a marching band that played the tune to Michael Jackson's "Thriller."Come Monday, the No. 1-ranked Djokovic will be back to work, hoping his opener against Paul-Henri Mathieu is the first of seven matches this month at the venue where he's had the most success in Grand Slam tennis.
