The "World Series" though is just teams from America and Canada isn't it? And Canada doesn't have its own independent league.In fairness, Baseball is every bit a world sport as rugby is. It's in the top 3 or 4 sports played and watched in the USA, Canada, Japan, Korea, Cuba, Domincan Republic, Mexico, Venezuala and quite a few other.
Incidentally, Ireland are ranked 50th in the World Baseball standings, higher then our football team !
Now maybe there are the best but there's not even the pretext of a real international competition.
