Federer brought his A game last night. So elegant. Majestic! I couldn't help thinking he was almost playing like a badminton player. The racquet speed, the wrist action, and the way he put the ball anywhere in the court. I used to be a badminton player. Badminton and tennis have a big difference. Because badminton is lighter, the shuttle speed is much faster, and there is a lot of wrist action, and there is a premium for sudden moves without any back swing. A top player is expected to put the bird anywhere in the court in any position; for example, back facing the net, one can flip the bird from one corner of the court to the opposite corner. These are things you are not supposed to do in tennis, "firm wrist" and all. I guess when you can play tennis like badminton, with a much heavier ball and racquet, you are playing at the ultimate level?
