Interesting it's available in eight countries: "United States, Canada, Australia, Brazil, Japan, Mexico, Puerto Rico, South Korea, and the United Kingdom, and will expand to additional countries at a later date."
Baseball is a very popular sport in many of these countries, especially Mexico, Japan, and Puerto Rico. I’d posit a guess that they continue to roll it out to other Latin American countries next.
I don't know about the rest of Latin America, but baseball is not popular at all in Brazil
I’m in the UK and have MLB TV. Hope these games aren’t blacked out.
