Dont worry. Adley to the rescue. The real question is going to be does Sisco's bat play well enough that he can stick given his defensive weaknesses and if so just where do you play him?
Can you keep him as a backup catcher?
Can you DH him?
Can he play any other field position?
Certainly the O's are pondering these questions and are working all the angles to figure it out.
I would play him some at 1st, and third. Maybe even try him at second.
A utility guy who can go behind the plate has value.
