Just wondering who hits the heaviest ball on tour?

I'm not entirely certain what 'heavy' actually means, but I believe a heavy ball has pace and spin. They both hit quite flat, but I've seen JMDP hit a few loopier balls, from memory. As for pace, I can't say.

nobody more so than Rosol that day vs Nadal

I think feds smears the ball, too

I've never seen anyone hit harden than some of Del Potro's shots in the USO 09 final. Rosol that day against Nadal didn't come close.

Rosol cracks the ball. Del Potro pounds it.
Del Potro hits the heavier ball.
If you think of this in terms of physics, momentum = mass x velocity.

Rosol has more racket speed (velocity) and less weight.

Del Potro adds more weight or mass behind the ball.

Here's an example of an analogy to describe a heavy ball.
If you're closing the car door and give it a shove and it doesn't close properly but then if you're carrying a bag of messages and give it an equal shove with the same velocity, you'll find the door closes because you have more momentum due to the extra mass behind your shove.

Rosol took the ball a lot earlier when he played Nadal than Delpo did when he played Ferrer, thus Rosol's ball got from A to B a lot earlier.

Rosol reached 99mph.

What don't you understand?

^ The puzzling phrase was highlighted.

I believe that DelPo hits with more spin on his shots overall. For the same forward velocity, the one with greater spin is the heavier ball. Heaviness is usually related to total momentum (linear & rotational) or total kinetic energy (linear & rotational).

Rosol's back hand is the biggest I have ever seen, I never saw somebody hit such winners against Nadal, He can hit winners of that side in a way people can't even react even being in the middle of the court.

A struck ball has two primary elements to consider: speed and spin. All of the tall guys tend to hit with high MPH when they choose to do so (presumably because their wingspan gives them the ability to produce enormous racket head speed).
