Cherokee, here is another thought. If your son really wants to continue being a 2 way guy (and I strongly recommend he does as a sophomore), why not have him play as a PO for the travel team with the caveat that he play with a lesser talented team in their organization as a position player ONLY, or for a completely different organization. If the team that wants him as a PO is a competitive team that plays in the high profile events, he will get noticed faster. He won't get noticed sitting or getting a few bats per tourney.
My son faced this delima. When he was a rising junior, he had one of the top travel teams in the country (East Cobb Astros) call him. They wanted him as a pitcher but promised he would get an opportunity to play outfield and hit. At the first practice, it was pretty apparent that he was gonna be a PO. There were a lot of guys who were better than him with the bat. Defensively, he was the best or maybe second best. Fast forward to 18U WWBA and 17U WWBA in 2014. The Astros at that time were a 17U/18U team. He had been giving the coach a fit to let him hit and play as we had scuffled scoring runs a couple games and had several guys K looking. He was like,"Hey coach, I will at least go down swinging." About our 3rd pool game against a really talented team (NE Roughnecks I think) he was inserted into the line up. I think he went 2 for 2 or 2 for 3 that day and led the team in batting average that tournament including a hit off of Luken Baker (then with Texas Sun Devils now TCU) on a 96 mph fastball. As a dad, that convinced me he could handle that velocity, no matter what happened moving forward. The next week was the 17U WWBA. I was certain son would be a 2 way guy. Before the first game, son is at batting cage with hitters. Coach sees him and pulls him to the side and asks him what he is doing. His response was to tell the coach that he figured he wanted him to play both ways. Coach said, son what would happen if you dove for a ball in the outfield or got your hand stepped on sliding into a base? You are far too valuable as a LHP throwing 92 than a hitter. That finally made a LOT of sense to me as a parent.
Now son kept hitting throughout HS, and was really good. He was good enough that his current college coach had the intention of giving him a chance to hit. If you read his bio information it says as much, not just a dad blowing smoke. After talking with a couple upperclassmen that were given the same opportunity, son just decided that he was going to focus on pitching. As a dad, possibly squinting through rose colored glasses, I am still confident he could hit and defend at his current school. But, we will never know as the game told him the mound was where his future is.
