In São Paulo’s Museu do Futebol, is a small, coffin-like room, on one wall of which grainy footage of the final game of the 1950 World Cup is played while an amplified heartbeat pounds. If there is an American approximation of this place, it’s the Baseball Reliquary, which doesn’t physically exist as much more than a peripatetic series of displays in SoCal libraries and occasional gatherings of fans to celebrate everything that makes baseball worth celebrating: Communist agitators, showmen, Jim Bouton teaching the knuckleball to fans, bubblegum cards and above all what it feels like to pick up a ball and throw it.
