Yeah Vincent buys a baseball team and then he learns that the comissioner of the league and other owners are conspiring to fix things so his team can't win the World Series. Suddenly, the players on Vincent's team get all bulked up...they all are hitting 75 home runs a year and the pitchers win 30 games each. After they winn the championship, Vincent further enriches the family by marketing the same juice to all the major leagues, and when a scandal breaks he blackmails the comissioner into resigning and taking all the blame. He then makes a deal to get the great great grandson of Rothstein to become the new comissioner. This not only gives him control of the sport of Baseball, but it also rebuilds a bridge between the Corleone Family and what was left of Hyman Roth's empire. As this is done Fidel Castro gets assassinated, and the rightful owners of expropriated properties in Havana get huge chunks of beachfront property whereupon the immediately rebuild their casinos, houses of ill repute and the rest.
