badminton is obviously the worlds fastest racket sport. tennis isn't as most shots don't reach the opponent for a while whereas badminton can play 2 or 3 shots in the time for tennis's one shot. badminton smash-207mph tennis serve-153mph i think that says it all. in a typical rally roddick hits 100mph forehand shots but in badminton a smash is like a roddick forehand so a badminton smash on a forehand is over twice the speed roddick hits his normal shots at. in my on opinion badminton is definately the fastest racket sport, no doubt about it! watch tennis and squash and then badminton and you will see a big difference in speed of movement and shot production.
