Nothing bizarre about that...the sports were brought by whomever had the biggest influence in the island. In the DR, Puerto Rico and Cuba that was The US...Reason why we play Baseball whereas Haitians, Jamaicans, etc...play soccer...and why nowadays you're starting to see Dominicans appear in The NBA or even the NFL. If there was interest in Soccer Dominicans could be just as good as anyone, but just like in The US it is just not a sport with a big following and I don't think will ever be.
Then Panama must be the exception to the rule
