Cuban righty Jose Contreras earned some early acclaim during his year and a half stint as a pitcher with the New York Yankees, but he's truly making a name for himself with the Chicago White Sox. During the 2005 season, he went 15-7 with a 3.61 ERA and helped lead his team to the World Series. This World Series baseball has been hand signed by Jose Contreras and comes with a Steiner Sports Certificate of Authenticity.
