See, I disagree with it not being important because of coming up with 2 outs. Seen plenty of 2 out rallies in fastpitch, I would like my best hitter to have a chance to get that going in the first inning rather than letting the other team go 3 up/3 down. Get your number 3 on and then hopefully your number 4 knocks her in. Also, I would prefer number 3 to be a balanced hitter. Someone who can consistently get a base hit and can also lay down a nice bunt-if the first 2 spots are speedy, a good bunt in the 3 spot can mean at least one scores.Again, that's the conventional logic. The reality is that the #3 hitter comes up with 2 outs, none on quite often - enough so that this spot isn't as important as some think it is.
Runners on is the measure for some spots, but not all. Obviosuly someone has to get on, first, hence the high OBP desired in the #1 slot.
I'm not opining here, just repeating the results of thorough statistical analyses.
Optimizing Your Lineup By The Book - Beyond the Box Score
Admittedly, the differences are small, but not insignificant.
Take it or leave it, but these stats don't lie.
I also don't understand the reasoning of not having your best at the 3 spot bc of potential 2 down. Isn't that potential there with any spot you place them in? What good does your 5 spot do you if they come up in the 2nd inning, with 1 down. They get on base, but the bottom of the order is behind them. So they stand there. In fastpitch I would guess that it is less likely for a home run to be hit than the metrics used to establish these stats. Also, aren't the stats being used from a time when baseball players were hitting more home runs than they currently are? Wouldnt that change the thinking? I can't even pretend to understand half the stuff written, so my questions are quite possibly stupid, lol.
I think if I was coaching I would do things a bit differently. I'm sure at higher levels there aren't necessarily any week hitters. At the level we currently play, I would like to see a balance in the line up, not necessarily in the skill set of the hitter, but in the hitters ability to put the ball in play. I would maybe have an unconventional bottom of the order. I'm not sure. Sometimes people need to be comfortable. I just read somewhere the reason Mark Mcquiwre hit the 3 spot when he won the homerun title was because he was comfortable there. He didn't feel the same pressure maybe, and he had a good guy behind him so pitchers couldn't pitch around him.
Really I know the order doesn't matter much, it's just something fun to talk about.
