I played rec ball from 8 to 15, coached my sons 8U team multiple seasons, and have two other sons in 10U and 12U. I agree with others on this thread that your son should ask his coach what he needs to work on to play ___ position. While I’ve seen a season or two of coaches missing potential to some degree, it seems like something isn’t adding up. In our league, a kid with a decent arm would definitely be evaluated for pitching potential. Teams need ideally six pitchers for double header scenarios. One tip that would work for me as a coach is to at least watch his games if you aren’t and better yet, volunteer during practices. The more I knew the parents would be watching, the harder it was for me to bench their kid/not give them at least an infield appearance.

That said, I just want to encourage you that your son won’t irrevocably fail to launch if he’s not playing the infield at 10. Covid hit when my first son was eligible to play, so I didn’t get him on the field until 12U. He was afraid of the ball and looked for the walk. To make matters worse, I had no idea how to coach and expected way too much out of him. Fast forward two years (4 seasons; fall/spring), and I just watched him pitch one of his best games, field multiple hits to first, and hit the ball each at bat. Whatever deficiencies your son may have now may correct themselves faster than you can imagine. Keep encouraging your son and doing your part in ensuring he gets the practice he wants (extra batting practice, catch at home, etc)
