Ian Beckles

I met him at the 2018 Florida State League Home Run Derby at George M. Steinbrenner Field in Tampa, Florida in 2018. He was there as the play-by-play announcer.
I had no idea he was scheduled to be there. I had been carrying this card with me for a few years because I knew he lived in the area.

Ian signed a 1991 Upper Deck Football card #390.
