Hector has a 2.13 ERA when throwing to Hank in 25.1 innings. Yes, I know, that's a noisy stat, a tiny sample size combined with an unsustainable babip (.219). All of those things are true. It's also true that pairing a pitcher with iffy control with a catcher proven to steal a lot of strikes (+58 this year, +136 last year) makes a lot of sense.
It's not the complete answer. If Hector is so wild that no amount of framing will even matter or if he runs into an ultra-patient offense he could still blow up for 7ER in 2 innings. For the moment I wouldn't change a thing.
