BallGameMaster is an all-in-one management system built for baseball and softball leagues and tournament organizers. It supports round-robin, knockout, group round-robin, double-elimination and custom formats, generates schedules with AI, syncs phone scoring to the web in real time, compiles batting, pitching and fielding stats automatically, and includes online registration, fee management and league community features.

Pain points · What happens every day

If any of these sound familiar, BallGameMaster was built for you.

Scheduling eats a whole weekend

Team counts, field slots and avoiding repeat matchups are all dragged around by hand in Excel; change one game and you redo the lot.

Scores reported in a LINE group

Scorers photograph the scoreboard and post it to the group, spectators keep asking what the score is, and results must be retyped after the game.

Nobody compiles player stats

Batting averages, pitching records and fielding data sit on paper sheets, so annual awards have nothing to stand on.

Registration, fees and rosters in separate Excel files

Team registration, player rosters and payments are managed separately, so reconciliation and eligibility checks start over every season.

Features · Six core capabilities

Every feature was shaped by a real user pain point.

League management

Create and manage multiple leagues with custom rules, season settings and divisions for full control of your tournament structure.

Scheduling

The AI scheduling engine generates matchup tables automatically, supports round-robin, knockout and other formats, and produces a full schedule in one click.

Live scoring

Score live from a phone and the score syncs instantly; spectators follow it on the web and miss no highlight.

Player stats

Batting averages, pitching records and fielding data at a glance, with individual and team reports generated automatically.

Registration system

Online team and player registration, fee management and roster management simplify sign-ups and cut administrative work.

Community

League announcements, game photo walls, MVP voting and highlight recaps build an active game community.

How it works · The process

Four steps from start to running.

  1. STEP 1
    Create league and season

    Set the format, divisions and rules; one account manages multiple leagues.

  2. STEP 2
    Teams register online

    Teams and players fill in forms and pay online, and rosters are filed automatically.

  3. STEP 3
    AI builds the schedule

    Choose a format and field slots and the system lays out the full matchup table, with manual fine-tuning available.

  4. STEP 4
    Phone scoring, stats build up automatically

    Score on a phone on game day, spectators watch live, and player stats and standings update automatically.
