I'm not a big fan of the Fan Cave but I'm not completely sure what it's supposed to be. In fact, I originally thought it was some kind of MLB team store and when I was in the area I tried to go in, only to find the door locked and then see a sign saying something to the effect that it was a working TV studio!
Incidentally, you might like to know that Tower Records used to occupy the space where the Fan Cave is now. For a long, long time after Tower closed, the space sat empty, except for one Christmas where it was a Toys R Us pop-up store, and a couple of other short-term usages.
This is home now - Citi Field, capacity 41,800 - and every seat in this ballpark seemingly filled, some standees as well, anticipating a piece of history as delivered by Mike Pelfrey, the 25-year-old from Wichita, Kansas. Into a windup, his first pitch in the history of Citi Field, a fastball for a called strike to Jody Gerut. Gerut off to a .214 start with no homers and one RBI. - Howie Rose calls the very first pitch thrown at Citi Field, April 13, 2009
