Sean Doolittle finally got to ride the bullpen cart!!!

There is a piece of beloved baseball lore that's been hiding in plain sight for 40 years: The bullpen cart. Those goofy, baseball-shaped carts that dominated baseball in the 1970s arrived with little fanfare and departed with even less.

As the D-backs honor their club history during their upcoming 20th anniversary season, they will also bring back a piece of baseball lore -- the bullpen cart.
