I haven't seen this mentioned and I don't know why.
I'd much rather have Kratz as our everyday catcher over Navarro. If he was allowed to play everyday I suspect he'd better at every single area of the game (except probably hitting for average). He hasn't really proven his offensive abilities in the majors during various short stints but his last 4+ years in the minors are quite good.
- Hitting for power and overall offense
- Throwing out runners
- Pitch-framing
- Game-calling
- Base-running/speed (minor upgrade, obviously)
This post is probably coming at a bad time given the good night Navarro had... nevertheless...
