Rawlings Official 2009 World Series baseball, signed by 21 members of the World Champion New York Yankees. This baseball originates from the collection of Joba Chamberlain, a pitcher from the team who sold off much of his collection some years ago. The signatures of modern baseball players are often illegible, but we can identify many of the signatures included here. Included are Derek Jeter (HOF), Mariano Rivera (HOF), Andy Pettite, Phil Hughes, Jose Molina, CC Sabathia, Joe Girardi, Mark Texeria, Robinson Cano, David Robertson, Jorge Posada, Chien-Ming Wang, Johnny Damon, and Nick Swisher. The baseball and signatures are beautiful, despite many of the actual signatures being illegible, which is an issue with the players and not the condition of the ball. Full LOA from James Spence Authentication.
