one thing I would like to see is statiscally are you better off taking a 1st pitch fastball for a strike or swinging.
Surely someone has crunched the numbers on the end results of both scenarios.
A good hitter will be out 70% of the time he puts the ball in play but that includes all pitches not just fastball strikes. But then again once ahead in the count the pitcher may start to nibble and fall behind and the hitter will see more pitches in that at bat
I have always told my son that the first pitch get me over fastball may be the best pitch to hit he sees in that at bat and have ecouraged him to jump on it. But I'm not positive it the correct approach.
