Diamond League Manager - Tabletop Baseball Scheduler & Standings

Diamond League Manager - Tabletop Baseball Scheduler & Standings

Run your whole dice-baseball league from one browser tab, from the opening-day schedule to the final standings.

You draft the teams and you roll the games. The tracking is where most home leagues fall apart: a spreadsheet that breaks the moment you add a team, or standings you end up recalculating by hand every week. Diamond League Manager handles all of that and gets out of the way.

Enter your teams, pick how long the season is, and it builds a proper balanced schedule. Then it tracks every score and keeps a live standings table, the same one you'd see in a real league office. Works with any tabletop baseball game you already play.

Build the schedule

Any number of teams, any season length you want

Full home-and-away round robin built around three-game series

Every pair meets both ways, and home and away games stay even across the season

No team ever plays more than two away series in a row, so nobody gets stuck on a marathon road trip

A fixture-quality check that shows you, team by team, exactly how the home and away runs fall

Optional real calendar dates, and a printable fill-in score sheet for playing away from the screen

Track the season

Enter each game's score and the table updates itself. Every column a league needs:

Wins, losses and winning percentage

Games behind the leader

Runs for, runs against and run differential

Current winning or losing streak

A colour-coded last-five form guide, most recent game ringed

Your season, backed up

Everything saves in your browser as you go. When you want a real backup, export the whole season to a single CSV, schedule and every score in one file. Clear your browser, switch to a different computer, come back next winter, load that file and the entire league is right where you left it. You can even edit scores in a spreadsheet and load them back in.

Who it's for

Anyone running a solo or group tabletop baseball league. It has no engine of its own, so it sits happily alongside whatever you play, from a dice-and-card draft league to a full stat-based replay. If you keep a season going, this keeps the paperwork.

How to use it

One HTML file. Double-click it, or drag it into any browser. No install, no sign-up, no account, no subscription, and it keeps working offline. Pay what you want on the way in.
