If the ump can’t get it right because the game has gotten too fast, they need to make it easier on him. They did this with instant replay. There has never more emphasis on spin rate and ball movement from pitchers. This game has gotten much harder to call balls and strikes. I look at it as just another step in the evolution of the game as the athletes get bigger, stronger, and better. The umps certainly are not. They need some help. Roboump is coming but that’s huge and will take time to get right. This is a small easy fix.
