I just got in an ALCS game used ball from the Cliff Lee- Andy Pettitte matchup in game 3 of the ALCS. Well I didn't even think about it being Andy Pettittes last start of his career. It's MLB authenticated and Steiner Authenticated. I love it! The only problem is that the MLB database has it listed as a ball used in the alcs. So there's no way to tell if it was pitched by Pettitte!
