Pitch f/x data

By , 10:51 PM

Let’s say that pitch f/x data tells us the following about a particular pitcher or group of pitchers:

On the average, the run value of a high inside fastball is -.001 where minus is good for the pitcher.  The run value of a low outside fastball is +.001.  In other words, the run value of the former is better than the run value of the latter.

Now, put all pitch sequence and game theory stuff aside.

In an average situation against an average batter, where those run values above absolutely apply, which pitch should a pitcher attempt to throw, and why?  We are just talking about one pitch, and again, put aside anything to do with pitch sequences and game theory.
