Mariano Rivera began his tenure with the Yankees in their farm system and played for the Columbus Clippers. The size XL Betlin Columbus Clippers jersey has a minor league patch on the left sleeve which dates it to 1995. There is a bright bold black sharpie signature by Rivera written across the Clippers patch on the front of the jersey. The jersey shows great game use with some minor staining. What an amazing find, the minor league jersey of a potential future HOFer. LOA.
