The only problem with that philosophy is that it goes against the physics of hitting. If a batter is fooled he'll start is bat early. If it's inside he hits it hard, foul or fair, because he gets the fat of the bat on the ball. If it's outside he hits it weak of the end of the bat or misses the ball. It's a matter of physics. That and ball bearings. It's all ball bearing nowdays. I can't speak to the ball bearings, but if a player swings very early on an inside pitch, he's going to pull it way foul. It doesn't matter if he hits it hard or soft... Yes, if he swings very early. But if he doesn't, the chances of "rubbing up a new one" are increased by pitching the change-up inside. The point is that a pitchers wants to decrease the chances that the hitter gets the sweet spot of the bat on the ball. Speeding up the bat is one way to do that. But if you don't speed it up enough, inside pitches go far. According to the article, Lilly throws change-ups about 11% of the time. I seriously doubt that hitters were sitting on his change. And, I gotta tell ya, change-ups -- wherever they are located -- fly very, very far if the hitter has the timing. Did you bother to read my other posts in this thread or did you just skip them? That's the point I think is important that the author didn't delve into, the frequency of the change-ups Lilly throws. In 2007 it was obviously a good pitch for him probably because of the frequency with which it was thrown (I have no data to back this up). However it's a risky pitch. Most hitters do not have the power to drive a ball to the opposite field when they are fooled on off-speed pitches away. They roll over the ball and ground it weakly or they pop it up weakly. A batter can get fooled on an inside fastball or breaking ball and hit it out. That's why pitchers don't pitch inside and that's why you hear color guys constantly complaining about pitching inside (i.e., they want them to do more of it).
