Federer, the world No. 3 tennis player, has remarked that he is often surprised not to see anti-doping testers after winning tournaments. He believes tennis needs more anti-doping testing to avoid issues seen in other sports. As the potential greatest tennis player ever, he expresses confidence in Switzerland's program but thinks out-of-competition testing could increase further. Federer reports being tested out of competition 5 times this year but more resources are needed for more frequent random testing to discourage any doping thoughts.
