Taylor Tinsley Changeup Breakdown

This is a video highlighting Taylor Tinsley's changeup and why it is so deceptive. She utilizes Effective Velocity Tunnels to disguise the changeup to look like a faster pitch. https://effectivevelocity.com/ This introduces the real definition of 'perceived velocity', the hitter perceives the pitch to be faster than it is, so in essence, they are swinging at a lie. The pitch is lying to the eyes of the hitter. The hitter is swinging at 'The Tunnel' not the actual changeup.
