Two problems. One solution.
League coordinators face two headaches that usually require two different tools:
Problem 1: Unfair lineups. Volunteer coaches use spreadsheets, napkins, or gut instinct. Parents complain. Kids sit on the bench too long. There's no consistency across teams.
Problem 2: League overhead. You're managing teams, coaches, divisions, and seasons, often with email threads and shared Google Sheets. There's no central place to organize it all.
One tool that solves both
Inning Wizard generates fair, balanced lineups in seconds and gives you a league admin dashboard to manage every team from one place. Position rotations, playing time balance, season-long history, coach invitations, division structure: all handled automatically. Every team gets the same standard of fairness. You stay in control without adding to your own workload.
Guaranteed fair playing time
Every kid plays infield and outfield. Bench time is spread evenly. The algorithm enforces it so coaches don't have to.
Season-long position tracking
The tool remembers every past game and builds each new lineup to improve fairness across the entire season, not just one game.
CSV roster import
Already have your rosters in another system? Export a CSV and import it directly. Works with exports from all major team management platforms. League admins can import every team's roster in one upload.
Position preferences that stick
Lock your pitcher and catcher. The rest of the roster rotates freely. Coaches stay in control of what matters most.
Drag-and-drop adjustments
Generated lineups can be tweaked with drag and drop. The math gets you 95% there; the coach makes the final call.
Multi-level admin structure
League admins manage divisions. Co-admins manage their own teams. Head coaches invite assistants. Everyone sees only what they need.
Works on any device, no install
Runs in any browser on phones, tablets, and laptops. No app to download. Most coaches are generating lineups within two minutes of signing in.
Bulk league setup in minutes
League admins can upload a single CSV with every team, player, and division. No manual data entry. Go from registration export to ready-to-generate in one step.
How it works for league administrators
Whether you're running a 6-team rec group or a 60-team city-wide league, you get a single admin account that manages everything. Create seasons, set up divisions, and invite each head coach. They manage their own rosters and generate lineups independently. You keep oversight without doing any of the work.
Already have your rosters from registration? Upload a single CSV file and import every team, player, and division at once. The importer auto-detects columns from all major team management platforms, so there's no manual data entry. Coaches can also import their own rosters individually from any CSV export.
Need to share admin duties? Invite co-admins for each division. They get full management access without needing a paid subscription of their own. One invoice covers the entire organization.
Coaches don't need to be tech-savvy. Add players, click generate, print or screenshot the lineup. That's it. Most coaches are up and running in under two minutes.
