About baseball, you are assuming open spaces that most countries don't have. In Cartagena, Colombia, for example, kids used to play a certain form of baseball with soda caps and the handle of a broomstick. It requires so much skill that not many kids can play it, and those who can, only got the coordination after certain age, but it's what they can get.

Basically an open field in a residential area with no cars or windows around is as rare in Nigeria or Argentina as an Olympic pool. So, no popular swimming sports here either.
