David Wright

I met him at Tradition Field, the New York Mets spring training facility in Port Saint Lucie, Florida in 2017.

I was there to get autographs from the fantasy camp coaches but David happened to show up that day to hit in the batting cages, several weeks before the spring training camp was to officially begin.

David signed a 2015 Topps Stadium Club card #193
