BlueLine is the umpire assignment platform built for youth baseball and softball leagues. From season games to playoff brackets to multi-day tournaments — everything your league needs to schedule, staff, and track officiating is in one place.
League administrators spend hours every week texting umpires, fielding last-minute cancellations, and trying to figure out whether enough officials are lined up for Saturday. When something goes wrong, there's no record of who was assigned, who showed up, or who didn't.
Two purpose-built experiences — one for leagues and tournament directors, one for umpire associations — connected on a single shared platform.
Post your games and qualified umpires self-assign to open slots. The qualification engine automatically filters each umpire to only the games they are certified for:
Every kind of game your league runs, all staffed the same way:
Link the umpire associations that contract with your league directly in the platform. Multiple organizations can serve the same league. Add or remove through the Umpire Orgs directory in your admin panel.
Add or bulk-import games from CSV. Manually assign any qualified umpire. Enter playoff scores — bracket advancement is automatic. Daily calendar with field columns and time-sorted game cards. Pull fill-rate, earnings, and obligation reports anytime.
Team managers submit structured ratings after every game — game control, rules knowledge, overall quality — tied to the specific game and umpire, and visible to org and league admins. Volunteer obligation tracking flags completed obligations and generates email summaries by team.
Every game card shows live weather conditions for that game's field location — temperature, wind, and conditions — pulled automatically from Open-Meteo. No more last-minute calls to check whether it's safe to play.

Set up your league profile, season dates, fields, and game types. Import your existing schedule from a spreadsheet.
Find and connect the umpire associations that provide your officials through the Umpire Orgs directory.
Add games individually or import from CSV. The system generates umpire slot requirements automatically by game type and division.
Qualified officials see open slots and claim them. You see fill status in real time. No coordinator loop for routine assignments.
Enter scores, advance brackets, track manager ratings, pull reports, and develop your officials — all season long.
For the first time, I know exactly which games I'm qualified for, what I'll earn, and how I'm improving — all from my phone before I even leave the house.
