Bob Gibson played 17-plus seasons with the Cardinals, winning 20 games five times over that span and establishing himself as the very definition of intimidation, competitiveness and dignity. One of the best athletes to ever play the game, he posted a 1.12 ERA in 1968, the lowest figure since 1914, and a factor in convincing baseball officials to lower the pitching mound the next year. Known as a premier big-game pitcher, Gibson posted World Series records of seven consecutive wins and 17 strikeouts in a game, both of which remain unbroken. Bob Gibson has hand signed this official Rawlings baseball with inscription HOF. A Steiner Sports Certificate of Authenticity is included.
