The way the schedule was put together...there could have been 3 bubbles...New York, Chicago and Los Angeles...cities with 2 MLB parks that could presumably host 5 games daily...or 4 with 1 day game at a nearby MiLB park.
This isn't a beer league softball tournement where guys sit around until a field opens up. It takes some time to prep for a game, and not stadium has a half dozen locker rooms, kitchens, etc. You're not going to play 4-5 games a day on any field and have Major League level baseball.
