Thanks for raising this, Doug. If there was one thing I could change about the game it wouldn't be getting rid of the DH (which I hate), it wouldn't be forbidding astroturf, it wouldn't be reducing ticket prices, it wouldn't be improving competitive balance, it would be implementation of Doug's suggestion. Nothing would improve the game more. The batters that know the strike zone and the pitchers who have the ability to pitch in the strike zone (most notably pitchers with control of their breaking pitches) would skyrocket in value. The game would be determined by the participants, not the administrators.
I do agree with the comment that I don't see how Molina's contribution adds up to 50 runs prevented in a year.
