No, it's actually not Joe Pepitone. It's Jim Mason. That's right, the man with a career 1.000 batting average and 4.000 slugging percentage in the World Series and the only Yankee to hit a home run in the 1976 World Series. Of course he only had one at-bat in the World Series, but he made the most of it.
