You are wrong. FWIW, my friend is pitching in one of these games on Wednesday, and Ichiro hits over .400 against him even when Ichiro doesn't know what is coming. That is just one example.

You don't realize how hard it is to recognize a slider half way to the plate and be able to make contact, if you know what is coming, then it's much MUCH easier.

Plus you can just waste the breaking stuff until he throws a fastball again. I stand to my original assessment that the league average would be about .140 points higher.

Plus, say you know a slider is coming... and the pitch starts at the low part of the K zone, you can just lay off it assuming it will drop out of the zone. This would help IMMENSELY.
