Good advice from all--thanks.
We do get a pitching schedule. I think son will be on it, probably designated as a RP in one of the games. That wouldn't be ideal, but is ok. Adding multiple P5 commits to a roster for one tournament does tend to shake things up. If the boy is not on the list at all, then yeah, I may need to start a new thread about how to deal with that... But as I said, his team has been fair to him and historically it is not a cut throat kind of organization. All will probably work out fine.
