It’s been a while since I was involved in Youth Baseball, but my understanding of the Little League rules is that the national organization charters a local league as an affiliate. That league can field any number of recreational or travel teams that play under the Little League rules.
When that local league competes in the “playoffs” to get to the Little League World Series, it can field a team made up of “all stars” of the best players within it’s organization. I don’t think they can have players who didn’t register with that organization to play, in other words, getting ringers from other Little League or youth baseball organizations.
Ah... yes. The “select” teams.
Thank you for clarifying for me.
