Rob Whalen

I met him at a Minor League game at Roger Dean Stadium in Jupiter, Florida in 2015, when the St. Lucie Mets came to play the Palm Beach Cardinals.
This was my first visit to Roger Dean Stadium, home of the Palm Beach Cardinals and Jupiter Hammerheads (Marlins).

Rob signed a 2015 Topps Pro Debut card #32.
