A 9-team single round-robin is a common format for recreational softball leagues. The math is clean: 36 games, 9 rounds, every team plays every other team exactly once, with one team sitting out each round.
This page lays out the full matchup schedule. Drop your team names into the 9 slots below and pair each game with a diamond slot on your calendar.
How a 9-Team Round-Robin Works
With 9 teams, the structure is:
- Total games: 36
- Rounds: 9
- Games per round: 4 (one team has a bye each round)
- Games per team: 8 (one against each opponent)
Because 9 is odd, the rotation includes a bye every round — each team gets exactly 1 bye across the season, spread out so the same team isn't sitting out repeatedly.
The Full Matchup Schedule
Below is a standard round-robin rotation for 9 teams. Teams are labeled 1–9. Replace the team labels with your actual team names when you build your schedule.

| Home | Away | |------|------| | Team 9 | Team 1 | | Team 8 | bye | | Team 7 | Team 2 | | Team 3 | Team 6 | | Team 5 | Team 4 |
Round 3
| Home | Away | |------|------| | Team 1 | Team 8 | | Team 7 | Team 9 | | Team 6 | bye | | Team 5 | Team 2 | | Team 3 | Team 4 |

This rotation uses the standard round-robin algorithm (fix one team, rotate the rest). Every team appears exactly once per round — except for the team on a bye that round, and no matchup is repeated.
What This Generator Doesn't Do
This is a matchup-and-slot starter — not a constraint solver. It won't:
- Automatically assign diamond slots based on team availability
- Detect conflicts if a team's preferred night changes mid-season
- Cascade reschedules — if a game moves, you manually update downstream games
- Balance rest time — depending on how you fill the slots, some teams may end up with back-to-back first pitchs
For leagues where those constraints matter — most leagues with more than a single diamond or meaningful team preferences — that's where a real schedule builder earns its keep.
Frequently Asked Questions
Can I use this for a different team count?
No — this matchup matrix is only valid for 9 teams. For other team counts, browse the other softball round-robin generators on the Softball schedules hub.
How are byes handled?
With 9 teams (odd), one team sits out each round. The rotation balances byes across the season so no team sits twice in a row, and every team gets the same number of byes overall.
Can I use this for other sports?
The matchup matrix is sport-agnostic — the same rotation works for any sport where every team plays every other team once. The download is formatted for softball (diamond slots, standard game blocks) but the matchup structure works for any sport that uses a round-robin.
What if a team drops out mid-season?
If a team drops, the round-robin structure becomes irregular and is best handled by re-generating the schedule from the new team count. For recreational softball leagues that experience mid-season changes regularly, the static matrix breaks down quickly — that's where LeagueNav's schedule builder helps.
