Holm rarely got used as a pinch hitter last season because Bochy wanted him available in case of injury to Benjie, or pinch running for Benjie. Having Sandoval around, usually playing first base opened things up a little. Then, 2 yrs ago IT happened and Pedro Feliz caught an inning or 2, competently. Images like this apparently upset Bochy and most other managers.
The proposal--guys who are future utility players like Matt Downs and Ryan Rohlinger should start practicing catching now, and keep it up all season. A half hour 2 or 3 times a week might be enough. They are athletes, they can catch the ball. They need to get used to wearing all that gear. Velez, Frandsen, Scheierholz and othes could add years to their careers if they were a credible third catcher.
Meanwhile management floats the idea of carrying 12 pitchers and no backup catcher besides Sandoval. Sounds smart to me since Holm plays so rarely.
