Lefty/righty splits are obviously a big part of daily fantasy baseball. I think utilizing splits is pretty important in cash games – maybe not as valuable as others believe, but still a big factor to consider. In tournaments, though, I’ve been utilizing lefty/righty splits less and less, for a few reasons.
The most important of those reasons is I’ve noticed a strong correlation between handedness and tournament ownership. One of the strategies I’ve been using a lot more lately is playing righty-dominant lineups against RHP. You get reduced ownership, and right-handed batters tend to not struggle against righties the same way lefty batters struggle vs southpaws.
Splits are obviously important over the long run, but the reduced popularity you see on batters facing the same handedness of pitcher – especially studs who often have near-even splits and can go off against anyone – means I think it’s worth it to reconsider how you set up lineups based on handedness/splits.
tl;dr Handedness splits are important, but people are weighing them too heavily.
