My son plays on the HS varsity summer team (he was asked though he will only be a Sophomore next year.) The HS team plays DH's twice a week, he usually pitches in one game in one DH and plays in the field in one game of the next DH. More than likely he will be on the sophomore team next year but he enjoys playing up with the team.
He also plays on a 15U travel team, which plays weekend tournaments. Though he claims some of the best pitching he has faced has been in the weekend tournaments.
