What is so hard to believe, a fast ball on a 140 ft. court, any kind of ability will produce a homerun. I bet you have never seen this either, It was a ball thrown by Eddy Fernandez who now plays at Miami. He threw a backhand which hit the front wall, then hit the floor, then hit the back wall, then hit the overhead screen. A winner I guess. And BTW, I did a second post where I attempted to clarify that the homeruns were done on a smaller court.
