quote:I would hope that a device to teach hitting would not violate an absolute.
How many times have you heard
Joe Morgan say" He got fooled but he kept his hands back and lined that ball for a hit". Hitters will get fooled with offspeed. It is common but great hitters make adjustments. The only absolute about hitting is that you better be able to make some adjustments. Nothing wrong with practicing this....young players might learn to do it.
Or, you could set the pitching machine on 68, thigh high, and hit away. Follow hitting absolutes on every swing and see how good the team hits when the real pitcher shows up.
