PHOENIX — From the outside of his home, the Arizona Diamondbacks flag hanging proudly is modest compared to what’s inside the museum-like home of Frank Gennario.
Gennario has been a season ticket holder since the first-ever pitch was thrown by a Diamondback player. He says he’s attended nearly every home and playoff game amounting to more than 2,000.

Watch the full story in the player above for an inside look at Gennario's home and the item he holds above all else.
