Nah, it's not that simple. Pitchers can definitely try too hard - or try to be too fine in certain situations if they know there's no room for error. That usually compounds into other issues. I f***ing love analytics as much as the next guy, but there's still some human component to it and this is a good example of it.
I've pitched in a men's league for the past 20 years. I realize it doesn't effect everyone the same, but it happens and it probably happens more in younger players.
