If or when they ever go to electronic calling of balls and strikes, hitters are really going to have to adjust to the pitch, high in the strike zone. In my opinion, the high pitch on the border, is the most non called strike pitch.
When i was a kid, my mom loved it when Bob Gibson, Sandy Koufax, Tom Seaver, etc pitched. Cause even though it was a school night, I wouldn't miss by bedtime. These guys are brutal.
