The Willie Mays World Series Most Valuable Player (MVP) Award is given to the Major League Baseball (MLB) player deemed to have the most impact on his team's performance in the World Series, which is the final round of the MLB postseason. The award was first presented in 1955 as the SPORT Magazine Award, but is now decided during the final game of the Series by a committee of reporters and officials present at the game.

Roland Glen Fingers is an American former right-handed relief pitcher in Major League Baseball who played for three teams between 1968 and 1985. His effectiveness helped to redefine the value of relievers within baseball and to usher in the modern closer role. A seven-time All-Star, he led the major leagues in saves three times, and was named Rolaids Relief Man of the Year four times. He first gained prominence as a member of the Oakland Athletics championship teams of the early 1970s, when his flamboyant handlebar mustache made him perhaps the most identifiable member of The Mustache Gang, which led Oakland to become the only non-New York Yankees team ever to win three consecutive World Series titles. Fingers was named the Most Valuable Player of the 1974 World Series after earning a win in the opener and saves in the last three games to secure the title.
