I agree that Swihart needs to spend time in AAA focusing on nothing but catching. The idea of having him available to step in at 3B should Pablo fail is a nice idea, but there is a good chance that Pablo will be just fine. And if Pablo sticks at third base, then Swihart is still left with no place to play. On top of that, his development as a catcher would be delayed once again.
If the Sox have any desire to see if Swihart can be a major league catcher, and they should, then they need to put him behind the plate and leave him there.
Pete Abraham nailed it with the following:
The Sox erred last season by making Swihart into a left fielder and not because he got injured. They allowed to him catch only 21 games before having him change positions. It was a reckless, short-sighted decision.
So, too, are proposals that Swihart could become a third baseman or a super-utility player.
Let him catch this season and see where it leads. A young, athletic catcher with above-average offensive skills is such a rarity. Swihart should be given every chance to succeed as a catcher.
