Farrell did state that he would have Swihart continue his duties as a catcher outside of games. He also stated that once Holt returns the Holt / Young platoon would resume.
The stick in the mud here is that Swihart is a pretty good hitter, probably better than both of those guys.
If Swihart hits well I don't see how he can not be in the lineup in left every day.
Maybe Young gets dealt since he is redundant. Swihart hits from both sides effectively, I believe. Why settle for a platoon hitter? Plus, Swihart look like he will be better defensively than Young.
Putting Holt back at the sub position is a good idea too.
