Novak Djokovic's cheque for winning the Australian Open on Sunday was more than the entire annual budget for anti-doping in tennis.
The total funding for the 2013 anti-doping programme stands at $2 million, paid for by the four grand slams, the International Tennis Federation and ATP and WTA Tours. The cost includes $400,000 for the administration of the programme, paid for by the ITF.
Of the 2,150 tests carried out by the ITF in 2011, the last set of figures available, 131 were blood tests and only 21 were out of competition.
