[Fallout 3] How are They Playing Baseball in Vault 101?

There is a reference to baseball in the G.O.A.T., the *little leaguer* perk says the Vault Dweller was the little league MVP and baseball equipment can be found throughout the vault. A flyer says that games are played in the atrium. There’s enough evidence that there is a familiarity with the game and that there is some organized play.

Is enough space in the vault for this to work? Are there any modifications to the rules?

It's likely that there is more to the vault than we see.  Maybe an elevator reaches floors that we haven't seen ourselves.

It wouldn't be huge, but they had a recreation area in Vault 81 down where the generator was that they repurposed.
