I've tried this and was not successful. I don't know if I wasn't doing it right or if it is because due to the construction of my hand thet the only part of my palm that touches the ball is a tiny spot below the index finger. I've tried stretched spans, relaxed spans, forward finger pitches, reverse finger pitches, and etc, and that is still all the palm I can get to touch the ball. I've noticed that others palms touch the ball like mine, some have more palm touching, and one person I used to bowl with has almost his whole palm touching. He and I have almost identical spans, yet when I throw his ball I still have almost no palm touching. Am I right to assume this is due to hand construction and that maybe some people can palm the ball and some can't?
