It is possible to throw a rising ping pong ball, put backspin on it.
Jim Palmer was often credited with a rising fastball, but there's no evidence that the ball was actually rising. I remain skeptical - want to see proof.
Yeah, it would be tough to prove but I'm going to try to put together some stuff over the next month or so to see if I can (yeah, good luck right?). But just looking at that pitch, I swear it is rising.
