Never heard of that tournament. GOOD LUCK. “World” ??? I think not.
The World Baseball Classic has been around since 2006. It’s been played in 2006, 2009, 2013, and now 2017. It’s evolved into an every four year tournament. As I recall, it was started to try to grow the sport of baseball overseas.
I haven’t followed it much, but, the players seem to be mostly major and minor league players who play in the US professionally, competing for the team representing their home country.
But there have been exceptions. One year, Mike Piazza was on the team from Italy, even though he’s American. But being of Italian descent they allowed him to play for Italy.
And all the Latin American players play for their home countries in this tournament. Ditto the Japanese and Korean major leaguers.
