Who better to tell the story of Bill Mazeroski's legendary 1960 World Series home run than the man himself? On this official National League (Feeney) baseball, Mazeroski carefully wrote his story of the only World Series Game 7 walk-off home run in baseball history. He wrote "I hit the world series winning home run off of Ralph Terry in the bottom of the ninth inning, Pittsburgh-10 NY-9" on the side panel, and "Thursday, Oct 13, 1960, NY Yankees vs Pittsburgh Pirates, 7th Game of World Series" on the north panel. The ball is in EX-MT condition.
