Andy Murray calls on tennis to get tough on drugs in the wake of the Lance Armstrong scandal in cycling Speaking to reporters on Monday, Murray addressed both sides of the issue. He drew a contrast between cycling - where it's all about "how many watts you're producing" - and the extraordinary physical skills required by high-level tennis. There's no drug that can teach you how to play a drop volley. But he also pointed out that doping penalties have not always been fully enforced, citing the case of Wayne Odesnik, who was caught with eight vials of human growth hormone in his luggage in 2010. Originally handed a two-year ban, Odesnik's sentence was later reduced. "That's what was frustrating for me," Murray said, "because we're going through all of this and they're being too lenient with guys that are travelling with human growth hormone to other countries. It's ridiculous. If somebody fails a test, don't just let them back into the sport 18 months earlier than what they should be. "The other thing with tennis is that there's a lot of testing at the top end," Murray added. But lower down there isn't anywhere near as much. With the "Whereabouts" form, I think only the top 50 singles players and maybe only the top ten doubles players have to do it." There is a theory that, if the ITF really wanted to make a statement, it could pick up dozens of positive tests at Challenger level. This is where the desperation is greatest, with hundreds of would-be stars struggling just to pay their travel costs. But if a really big fish happened to be caught, would the tennis authorities be prepared to expose them? Andre Agassi's 2009 autobiography, Open, broke the story that he had tested positive for crystal meth - a recreational drug - fully 12 years earlier. Yet the information had never escaped an inner circle of ATP executives and the independent panel who decided to accept Agassi's "accidental ingestion" excuse. More recently, further questions have been raised by the involvement of Luis Garcia del Moral - team doctor for US Postal during Armstrong's heyday - in a tennis academy in Valencia where Sara Errani, David Ferrer and former world No1 Dinara Safina have all trained. However, there is no suggestion that any of these players have taken drugs. Murray clearly does not believe that tennis has an endemic doping problem. "Since 1990 we've had 65 positive tests," he said, "and ten of those have been recreational." But there was a warning in the recent interview that Dick Pound, the founder of WADA, gave to USA Today. Pound asked whether the ITF's program, and others like it, "are actually designed to succeed or designed to fail and merely cover their butts."
