Don Larsens baseball career can be defined by the historic events that took place on October 8 1956. On that day Larsen became the first and only player in MLB history to throw a perfect game during World Series Play. Perfection took just 97 pitches and only went to a three-ball count once to beat the Brooklyn Dodgers in Game 5 of the World Series. Commemorate Larsens accomplishment with this hand-signed MLB baseball with the inscription WS PG 10-8-56. His autograph is guaranteed authentic with a Steiner Sports Certificate of Authenticity and accompanying tamper-evident Steiner Hologram.
