I agree with all of that, but that is on average and not in a park as homer prone as Rogers centre. I would say that the groundball pitchers have a higher percentage, but fly ball pitchers have the volume. I personally would love to see a stat that is K% + IFFB%, It could be a clean out stat or something. If Estrada has a HR/9 of 1.4 I can't see how he will be useful.
