He doesn't bitch to the media, but he constantly bickers with game officials about everything from balls and strikes to Safe calls etc etc etc.
If i had my way, the Sox would've gotten Ronny Paulino and his .881 career OPS vs lefties (which includes a .390 OBP). He's never been a regular, but he'd be perfect as a complimentary piece.
On the other hand, i'll say what i always say, we're looking at things from the outside, as fans, we're not talent evaluators or statisticians. There has to be a reason why they're going so hard after Martin instead of going after two of the guys mentioned above, who are much much cheaper.
That being said, carrying three catchers makes zero sense, so Salty better still have an option.
