Novak Djokovic (Serbian: Новак Ђоковић, Novak Đoković or Novak Djoković, pronounced [ˈnɔvaːk 'ʥɔːkɔviʨ], listen (help·info)), born May 22, 1987 in Belgrade, Serbia (part of Yugoslavia at the time), is a Serbian professional tennis player.
In January 2008, he won his first Grand Slam title at the Australian Open. After a straight sets win over World No. 1 and defending champion Roger Federer in the semifinals, Djokovic won the final in four sets against Jo-Wilfried Tsonga. He thereby became the first player representing Serbia ever to win a Grand Slam singles title and the youngest player in the open era to have reached all four Grand Slam semifinals.[citation needed]
Djokovic was the runner-up at the 2007 US Open and has reached five Masters Series finals, winning four of them. He also reached the semifinals of the 2007 and 2008 French Opens and the 2007 Wimbledon Championships.
