Unfamiliar with some of the top stars in Cuban baseball? That is certain the change in the wake of this past week's exhibition game in Havana between the Cuban National team and the Baltimore Orioles. The two teams are expected to meet again in May in Baltimore if Fidel Castro doesn't back out of the reciprocal part of the agreement. A concern: some of the Cubans could defect to the United States and major league owners would welcome the chance to sign some of the top talent from Cuba.
