ATP World Tour Finals draw

Group A: Novak Djokovic, Andy Murray, Tomas Berdych, Jo-Wilfried Tsongs

Group B: Roger Federer, David Ferrer, Juan Martin Del Potro, Janko TipsarevicLONDON - Roger Federer wants more drug testing in tennis and says he is being tested less than in previous years.The 17-time Grand Slam winner was asked about the current regime after Andy Murray had called for more testing.  "I feel I’m being less tested now than six, seven, eight years ago,” said the world number one."I don’t know the reasons we are being tested less and I agree with Andy, we don’t do a lot of blood testing during the year. I’m OK having more of that.”The available International Tennis Federation anti-doping records only highlight individual players for the last two years, and show that Federer underwent four to six in-competition and one to three out-of-competition tests during 2011, and more than seven in-competition and one to three out-of-competition tests during 2010.These figures are for ITF and World Anti-Doping Agency (Wada) tests and do not include those carried out by national anti-doping organisations.It is not specified whether the ITF/Wada tests used urine or blood samples, but the ITF data does show that only 18 male specimens were collected through out-of-competition blood testing in tennis throughout the whole of 2011, and six during 2010.Agencies
