These cards, inserted into 1997 Upper Deck Series 1, were the first game-used jersey patches used in baseball cards. Someone explain to me how this 3-card set landed on a checklist of Ken Griffey, Tony Gwynn, and…. Rey Ordoñez?? 🤷‍♂ I have fond memories of the guy as a Mets fan in the late 90’s. Couldn’t hit to save his life, but such a smooth glove.
