what about pitch speed? what about which specific pitcher a pitch came from? even the same pitch is different from one pitcher to the next.
a cutter from Mariano Rivera isn't going to be the same as a cutter from another pitcher. not all fastballs are equal, they can vary from pitcher to pitcher to pitcher.
different pitchers have different specialty pitches that are not going to be the same as others. a pitcher who can throw a great change up isn't going to be the same as another pitcher with an average change up. if you look at a chart that says "X"% of change ups, is that taking into account who the change ups came from? or any other pitch?
what about taking into account whether the pitcher was pitching from the windup compared to from the stretch? these are things can can lead to different results.
these may be small things, but they factor into the results and can't just be ignored.
what if you took a pitcher to see how he reacts on his next pitch after giving up a HR. different pitchers could have it effect them differently. some can get upset and lose their composure. some may get upset and hit/throw at the next batter. I've seen it happen. if a pitcher gave up 20 HR in a season, then he would have 20 times when he would have a 1st pitch after that. but of course it's easy for one to say, small sample size.
it's happened different times when a pitcher can give up a HR, and then intentionally hit/throw at the next batter. so why did he do that? what about when the opposing pitcher comes out for the next inning and he intentionally hits/throws at the batter? is it going to specifically say that in the statistics? or does that go down simply as HBP?
this is all the evidence I need.
But if the pitcher and catcher are worried enough about Ethier in the on-deck circle while Kemp is in the batter's box, Maddon would argue that all the run-expectancy charts and data don't mean anything. Kemp will see better pitches because Ethier is in the pitcher's head.
"Absolutely -- or even the manager's head, or even the pitching coach's head or even whomever's head," Maddon said. "Everyone talks about the data and how wonderful it is, and I'm truly a believer, but there's also the buy-in component also. Unless you have total buy-in from everybody involved, it doesn't necessarily have the same impact."that from a major league manager who is in the game on a daily basis.In other words, as Maddon said, lineup protection will exist so long as the people on the mound, behind the plate and in the dugout believe it's important.
