Robson notes that "the ITF recently concluded its own investigation of the del Moral, which included interviews with players."
However, the biggest piece of information comes courtesy of Janko Tipsaravic:
Janko Tipsarevic, who finished in the top 10 last year for the first time, said he had been tested frequently "maybe because I broke through."
The ninth-ranked Serb described how specimen handlers showed up at his door in Africa where he trains during the offseason.
"They came to me in Kenya," he said incredulously. "I believe that tennis is way cleaner than people think it is," added Tipsarevic, who reached the U.S. Open quarterfinals.I'd suggest Tipsarevic pick a new training location because the Kenyan police, Athletics Kenya and the World Anti-Doping Agency are currently conducting a doping probe in Kenya, following reports that "doping is rife among Kenya’s runners and the foreign athletes who train in the Rift Valley." Do any other players train in Kenya?
Here's the best quote of the article: '[Dick] Pound said the ultimate question is whether the ITF's program, and others like it, "are actually designed to succeed or designed to fail and merely cover their butts."'
