The only thing I can add is the cream floats to the top. Don’t get discouraged if it takes a few weeks to a month for him to earn his spot. From what you are stating making the team should not be an issue. Finding the starting roster might take some time. Even if he appears to be the best option quickly.
Also, the reverse might happen which could cause some riff amongst parents. Your son comes out late and takes/earns a spot from a player who has committed to baseball earlier. Parents might feel their son was cheated because they think the commitment can make up for actual skill.
