I was thinking I'd just let him catch-- but his DUR = 53, and catchers fatigue somewhat faster than other players (I think).
So either play him in RF-- where you can play him, I dunno, every other day or so without fatiguing, or let him catch about 35-40% of the time (something like C vs LHP + DH in your 6 games in AL parks). In either case he's your everyday starting something down the stretch and in the playoffs.
