"Don't get beat with your second or third best pitch." I just heard Ron Darling echo this popular sentiment on the Mets broadcast. How does this make sense? It seems to me that the only way for one to avoid getting beaten on his second or third best pitch is to only throw one pitch. Everyone knows that, with the possible exception of a prime Mariano Rivera, pitchers need more than one pitch to get Major League hitters out. That is why catchers have to place a varying amount of digits betwixt their squatting legs before each pitch. It's kind of a big part of the game.
Saying "Don't get beat with your second or third best pitch" is tantamount to saying "Be Mariano Rivera". I don't think that that kind of advice is very instructive for the pitchers that lack the ability to throw a 95 MPH fastball that breaks 8 inches, without making the catcher move his mitt.
