One generation isn't THAT thin... I guess I'm not looking up the WBC by-laws and I might be conflating it with the Olympics, but doesn't one of your parents have to be citizens/first gen immigrants in order to play for a country?
There is an innate proviniciality to athletics. At least in the traditional aspect of how most of America and Americans view team sports. Celebrating your roots through HEALTHY, social, communal competition is beautiful.
