Bernie's slices are ridiculously good. He hits them with so much depth do often, I think he's deffinately got one of the top five slices in the world I'd probably say after federer and close to on par with Murray IMO
Yeah his slice is like Federer's.
He moves to the backhand and then just gently touches the ball, balls goes near baseline. It is a thing of beauty.
He always had a good slice, but now it is better because his footwork has greatly improved.
