Since the advent of the World Series MVP in 1955, the Yankees have won 11 championships. They’ve had 12 players named Series MVP, as Bobby Richardson won it in 1960 in a losing effort. If you look through those 12 players, pretty much all of them are pretty notable players. The most “random” winner is maybe Scott Brosius, but even he had been an All-Star that same season in 1998.
However, it takes more than one player and contributions from everywhere in order to win a World Series. Some heroes of a championship will be the star player or the ace pitcher.
