Fidel Castro, The New York Giant Who Wasn't

In the 1940s, the baseball team the New York Giants scouted a young Cuban law student named Fidel Castro, and even offered him a $5000 signing bonus. He turned them down, thereby, as historian Lois Browne put it, "leaving North Americans to ponder one of the more intruiguing 'what ifs' of modern history."
