Format, rules & venue
How a tournament day works
- One-day events. Every division plays a single day, Saturday or Sunday.
- 4-team brackets, 2-game guarantee. Game 1 and Game 2 are the opening matchups. The two losers play Game 3; the two winners play Game 4 for the title.
- Game slots every 2 hours 15 minutes, first pitch around 8:00 AM. The fields have no lights, so the last game finishes before dark. Coaches get the day's schedule the week of the event.
- A and B levels. For 11U and up, coaches pick the level: A for competitive teams, B for developing teams. 9U and 10U play one combined level, seeded using what coaches tell us at registration. The tournament may move a team that's clearly in the wrong level.
- Every weekend stands on its own. No points, no qualifying, no bids. Just good games.
