The only pitcher ever to win four consecutive Cy Young Awards, Greg Maddux is a surefire Hall of Famer, and "The Professor" signed and dated this baseball that he used to win his 309th career game on June 4, 2005. The signature, which includes the number 309, is in 8/10 blue ballpoint pen, and has been authenticated by Major League Baseball. There is evidence of nice use. The eight-time All-Star was also no slouch with a glove, either, as evidenced by his 18 Gold Glove Awards.
