Too many variables to really know or care for that matter. Enjoy whatever level he is at, you are worrying about something you have no control over - it is not worth it.
FYI my son played on the Freshmen team, while some other kids were moved up. He played every game in multiple positions developed as a result of it. The following year he was a starter on the Varsity team and by the end of the season he was the number 2 pitcher, and was hitting in the 4 hole as a Soph. I was just happy to go watch him play and have fun as a contributor.
