Who earned the nickname Mr October for his World Series play?
Reggie Jackson is the baseball player that earned the nickname of Mr. October for his World Series play.
He personally has none because he is not a pitcher, but we can say he was very much responsible for one important win for his team, the Philadelphia Phillies, in the 2008 world series. It was Ruiz's base hit up the third base line in game three that was the winning hit (a walk-off win, in fact); that clutch single earned for him the nickname "Mr. October."
