DY would win 6-0, 6-0. He makes mistakes against other pros b/c of the
pressure and also the incoming balls are harder and better placed than the ones
you'd be hitting to him. His opponents cover much more court than you so
he is forced to go for much more.
It's like asking a MLB player that strikes out 150x a year to try to hit a
stationary ball on a T. He's not going whiff 3x.
