Robinson Cano’s batting spot
John Walsh and Steven Goldman.
Two points:
1. When you see a statistical significant to p < whatever-number observed split, that does NOT mean that the observed split it significant at that level. It means that the NON-ZERO difference is significant at that level. So, if let’s say you have a .400 wOBA in one split and .300 in the other, and it’s significant at p=.04, then it means that it could very well be .335 and .334 as the true splits. It’s non-zero.
2. Other than leadoff hitter, if you can find me a one-position switch of a .300 to .360 wOBA hitter that will cause more than a 10-run difference, I will be impressed.
