Every mlb team has a presence in the DR and many in other Caribbean countries. Businesses own teams that furnish equipment. There are several baseball academies. They’ve turned the DR into a baseball pipeline and those that are good enough, make it to the States. Again, it’s cultural there. Has been for 80 years. That doesn’t happen here. You could even argue it’s unethical.
The idea that basketball isn’t as bad if not worse than baseball and soccer travel leagues is absurd. It’s where travel ball started. AAU ball, Nike camps, adidas camps, and others are where basketball players shine. Invites to any of those are what opens the door to get recruited.
