Bill Mazeroski's 1960 World Series home run was a baseball play that occurred in Game 7 of the 1960 World Series on October 13, 1960, at Forbes Field in Pittsburgh, Pennsylvania. Leading off the bottom of ninth, in a 9–9 tie and with the count one ball, zero strikes, Mazeroski hit a line drive toward deep left field that cleared the wall for a solo home run. Mazeroski homered off of New York Yankees pitcher Ralph Terry to end the Series, giving the Pirates a 10–9 win and their first championship since 1925. It is the only Game 7 walk-off home run in World Series history.
