The fingers can add more velocity than some realize. My baseball catching and pitching demonstrate the power in the fingers with an 85 mph fast ball to a 65 mph change up. The only difference was the fingers.I've noticed most of them seem to get a lot of pace with very little movement. I don't know if they can just snap their arm that much faster than me or if there's something subtle I'm missing. My best is about 18 and I almost gave myself a hernia. I haven't clocked my speed in a while but I seem to be doing well for me at maybe 16 mph. I should probably switch to kilometers per hour.
