Head of Royal & Ancient says no evidence of doping in golf in wake of track turmoil

The head of golf's governing body says there is no evidence of doping in the sport and emphasizes there will be no complacency in the fight to keep it drug-free.

Track and field is in turmoil after two of the world's top sprinters, Tyson Gay and Asafa Powell, confirmed they have failed doping tests. But Royal & Ancient chief executive Peter Dawson says his organization is "right on the case" and that "anti-doping policies do as much as they can to trap miscreants."

Dawson says: "I have no particular evidence of a problem. Everything I hear is anecdotal and hasn't had very much specific behind it."

Dawson adds that players who want to compete in the 2016 Olympics will have to follow more stringent doping policies adopted by the International Golf Federation.
