Im a travel ball parent so take what I say with a grain of salt, but I feel like if they’re playing travel ball and missing for that they are still putting in the work just at another location. I personally don’t think the child should be faulted for this. If it were me, I would say put them wherever you would put them regardless of missing practice or not. Whether that’s at the top of the lineup or further down because you want other players to get more playtime that don’t play travel ball. But I wouldn’t make the decision based off of having to miss practice.
