Preston Mattingly

I met him at Paul Owens Training Facility at Carpenter Complex, the Philadelphia Phillies spring training facility in Clearwater, Florida in 2024.

I met his father, Don nearly 30 years earlier.

Preston signed a 2006 TriStar Prospects Plus card #22.

Jesus Martinez

I met him at a Minor League game at Jack Russell Memorial Stadium in Clearwater, Florida in 1994, when the Vero Beach Dodgers came to play the Clearwater Phillies.
Ironically, I got his brother, Ramon's autograph in the same exact spot at the stadium during spring training earlier that year.

Jesus signed a 1993 Classic Best Gold card #133.
