Baseballs during a game
Harvey The Rabbit Baseball Delivery 1969
Matthew asked: What happens if an umpire runs out of baseballs?
Rick answered: Matthew, thank you for your question.
New baseballs are kept in the home teams dugout.
One of the bat-boys generally will run out to the plate umpire when he signals he needs more.
In the photo above, an interesting experiment by the Oakland A's owner, Charlie Finley in 1969.
They created Harvey The Rabbit machine, which was underground. The plate umpire would go over, step on a a device to raise Harvey, umpire would take the number he needed, then lower the device.
Yours in baseball,
