Should Hanigan catch CoCo on a regular basis?

I've looked at the numbers and after watching last nights game -it just keeps bothering me that when CoCo pitches to Hanigan he seems to do a much better job.

I looked at the lifetime splits in the hopes of seeing a bigger sample size: Hanigan has caught 78 innings and his ERA with Hannigan behind the plate is 2.10. His K/BB ratio is 2.33. K/9 inn pitched is 9.00.

When pitching to Hernandez, Coco's ERA is 4.76 (in 47 innings). His K/BB is 1.22. His K/9 inn pitched is 6.5.

What I'm not clear about is how much BaBIP plays into the numbers: Coco with Hanigan catching has a Babip of is .274 and Ramon's is .323.

I'm going to try to normalize these figures and see what we get (i'm hoping my math is correct): if my math is correct (and i'm not near enough good at math anymore to even make this kind of post, but here goes...). Hanigan's normalized OPS would be about .631. Ramon's normalized OPS would be about .658. As you can see there's not a lot of difference. Hanigan's adjusted ERA (with a a normalized BaBIP of .300) would be about 2.26 ERA and Ramon's adjusted normalized ERA would be about 4.40.

Imho, there's something signifigant going on, but is it enough to make a change and have Hanigan catch CoCo everytime he pitches. I'm not sure -it's possible that the sample size is waaaay too small. It's possible that Hanigan has been the catcher when CoCo has faced the 7,8,9 hitters.

One last thought: there have been 23 catchers who have caught CoCo over his career. If you take the 12 guys who have caught him most and look at their numbers what you see is this:

Ramon's CERA is 9 out of 12. Ramon's K/BB rate is 11 out of 12. His K/9inn rate is 11 out of 12.

Hanigan's CERA is 1 out of 12. Hanigan's K/BB is 5 out of 12. His K/9inn rate is 6 out of 12.

Maybe it's not enough to make a change....but i'd sure think about it.
