Suzuki is a better catcher today. In terms of framing and throwing he has been below average for years. That isn't going to change.
Pinto did better last September in his call up when he was getting more consistent play and the numbers weren't anchored down with the bias of catching primarily Deduno.
In any case, Suzuki isn't a good solution for 2015. We need to know if Pinto can be a solution. Assuming the a Twins are not within a few games of the wild card, he needs to catch 6 games a week starting August 1.
If Klutchuki can continue anywhere near the numbers he is having and the pitchers have no gripes working with him I have no problem at all with him being a solution for 2015. If Pinto can force the Twins hand to get him back up to the Majors that will be a good problem.
