If you're talking about a home run WITH one bounce on the floor
then I have seen it many times. That's often referred to as a
home run....front wall, back wall, bounce on floor, front wall....without
your opponent being able to get to the ball.
If you are talking about going front wall to back wall and then
to front wall again WITHOUT A BOUNCE...I say that is impossible.
Maybe if there was no overhead screen at all, then someone could
throw a low rising shot that climbs even after hitting the back
wall and somehow has enough to get to the front wall. But with
where the overhead screens are on the canchas in the U.S. I say
it cannot be done.
