First it was baseball, then the witch-hunt progressed through the other professional sports, going as far as NASCAR and Formula1. So, it makes logic sense to say that it was only a matter of time before the issues of athletic doping entered into the motorcycle racing world.
While the issue of doping in motorsports seems almost absurd, considering the benefits of athletic doping are deminimus when machinery takes center-stage, it would seem our beloved sport is not immune from athletes looking for that extra edge during competition.
UPDATE: David Emmett of has revealed in the comments below that Rodríguez, while testing positive during a doping screening, in fact had recreation drugs in his system, not performance enhancing drugs as we had thought earlier. Thanks for the tip David.
