One more spin drill for riseball. You would be amazed at how many young pitchers have difficulty putting backspin on a ball or a spinner or a cannonball. This is why I am a proponent of learning riseball spin at an early age.......but don't expect it to be an effective pitch until a reasonable speed can be achieved when throwing a riseball. Reasonable speed swags= 54mph/14-16U, 58mph/18U-moderate college, 62mph/higher level college
