nope. in fact, im pretty sure it agined fans. Ad it gained players from different countries. The MLB is so different from the WBC, it couldnt change the way i look at the MLB.  Ive been a Knicks, Jets, Mets and Rangers fan since im on this earth. And besides for 94 ( rangers) and 86( mets) it has been a sort of hell-hole to be a fan of those teams. But even thugh they lose, i stay strong. Stay strong for the Americans and soon enough youll get rewarded with good play.
