I think coach will leave him in as long as he can
Being that it is his first game action of the year, I would assume he will be on a pretty low pitch count. I have no clue how much work he has been getting in practice, but I wouldn't be shocked to see him go 3 innings and get pulled.
On the other hand, not sure how many pitchers CPM wants to use in these 2 midweek games going into such a big weekend series. He may platoon pitch in both games leaving everyone available for the weekend, or let his starters go as long as possible.
