I'm not much of a baseball fan, but checking out the WBC has been rather interesting. It started on the 5th and there have been several good games/surprises.
The Netherlands beat the Dominican Republic 3-2...that's right a European team dumped the team from a prime baseball-loving country!
Australia made their WBC debut beating Mexico in Mexico City...in just 8 innings, due to the mercy rule (they won 17-7!!).
The US is currently unbeaten beating Canada 6-5 and Venezuela 15-6 (take that Chavez!).
Unfortunately for the two surprises, the Netherlands faces Puerto Rico next and Australia faces Cuba. Fortunately, this is a double elimination tournament.
For news/scores, check out the official website.
For a bracket, the one on Wikipedia is clearer and more detailed.
