Nadal: Dope testing unfair to players

ROTTERDAM: Tennis is paying the price for being an Olympic sport and its new dope testing regime treats players like criminals, world No 1 Rafa Nadal says.

The Spaniard is leading criticism against the procedure adopted by the Association of Tennis Professionals (ATP), who signed the World Anti-Doping agency (WADA) protocol last year.

"It is not fair to have persecution like that," Nadal told reporters at the World Indoor Tournament in Rotterdam.
