WBC = MLB Spring Training. Great marketing idea, not going to be anything near what people are expecting or wanting. The DR is going to have a great lineup but they will get 2 innings out of Pedro, an inning out of Francisco Cordero and then... ummm. Well at least they will get 2 innings out of Bartolo the next game and then... ummm.
30 man rosters and fairly strict pitch counts, they are probably going to carry at least 16 pitchers.
I'll take my chances with the US team.
