Jimenez is as bad as Thole offensively and I don't think he's had much practice at all with Dickey. Considering the learning curve, he's not really worth it as a temporary solution.
There were some intriguing catchers in the rule 5. Kratz only signed a MiLB deal. It wouldn't have been hard to bring in a guy to a least compete with Thole in the spring.
It's expecting better results from exactly the same thing. How about using the roster spot more creatively than on another short side of the platoon dh with a suspect bat? I'd much rather call up Pompey.
