[Star Trek DS9] How did two entire baseball teams and a full baseball field fit into one of Quark's small holosuites?

I understand how the holosuites use holograms and replicator technology to produce solid holograms. Even with all that technology the holosuites (or holodeck) have physical walls with a finite size. How were they able to compensate for that?

Holosuites have improvements on holodeck technology, as found on the Enterprise.  If you have two people in an active Holodeck run away from each other for as long as possible, they will not hit the walls of the physical room.

Why?

Because force fields. They use force fields as a sort of 'treadmill' under your feet, giving you the illusion that the ground is moving underneath you while, in fact, you're staying in the same place.

As for how two teams could fit? Well, you could easily fit half a dozen people in each room. They were smaller than holodecks, yes, but they weren't so small you couldn't have a group in there. They'd just have to 'connect' holosuite projections so they could deal with each other in real time.

Thus, the Vulcans dealt with a hologram of Sisko's team, carrying out their actions in live-action, and Sisko's team dealt with holograms of the Vulcan team, mimicking their plays perfectly as soon as the Vulcans made them.
