William Stanley Mazeroski is an American former baseball second baseman who played 17 seasons in Major League Baseball (MLB) for the Pittsburgh Pirates from 1956 to 1972. He is most remembered for perhaps the most iconic home run in baseball history, a dramatic ninth-inning drive in Game 7 that beat the heavily favored New York Yankees in the 1960 World Series. It remains the only walk-off home run to clinch a Game 7 World Series championship in major league history. ESPN ranked the World Series winner at the top of its list of 100 Greatest Home Runs of All Time, while Sports Illustrated had it eighth on its compilation of 100 Greatest Moments in Sports History. He received the Babe Ruth Award for his World Series performance.
