I already know that there is no evidence to support the existence of the clutch hitter.Most people who study sabermetrics -- including Bill James -- say there it. And evidence aside, the existence of a clutch hitter, from a logical standpoint, from an intuitive standpoint, doesn't hold water. Because if a batter had the ability to elevate his hitting in order to bring home the runner on third base, then he'd know enough about the importance of being that runner on third base in the first place. And so therefore, he'd try just as hard in those at bats when no one was on base to get to third base on his own.Piss poor logic. You can't hit triples to order. But you can hit a single or a sacrifice fly to bring a runner in. If a batter had the ability to bat better at key moments, why wouldn't he use those "magic clutch powers" to hit safely at all times, instead of limiting his use of the clutch to RISP's. Wouldn't he wanna bat 1.000 for the season? Wouldn't he wanna hit a homer every time up?Sure he would, but that's irrelevant, since those aren't going to happen. But batters are human beings. Some get nervous in clutch situations. Some love being in them. If a batter gets flustered by the situation, then he's going to be worse when they come up. And if he seeks out the situation, he's going to be better. Choking in sports is a known psychological issue. Just ask Rick Ankiel why he's not on the mound these days. It has to do with thinking about things you should be doing automatically. Ankiel forgot how to throw a baseball -- a talent he'd been doing for years -- and started to think about the aspects of it instead of just throwing the ball. He is an extreme case, but clearly there are players who overthink matters when faced with pressure. On the other hand, there should be players who are more comfortable when the pressure is on, and are thus able to hit better in those situations. There are no numbers, not because it doesn't exist, but because no one has yet devised a way to quantify a clutch situation. RISP is not necessarily clutch (if you team is ahead by ten runs, it doesn't matter if you drive in anyone else).
