Welcome to Bullpen Report — Protecting Young Arms Across Every Team


TL;DR: Bullpen Report gives coaches real-time visibility into every pitcher's arm health across every team they play for — and gives parents a free window into their son's ARM status, rest calendar, and pitch history. Every outing logged updates every coach automatically.

If your son pitches for more than one team — rec, travel, school, tournament — you already know the problem. Every coach tracks his own game. Nobody adds it up. By the time Saturday's travel coach puts your son on the mound, nobody at that field knows he threw 52 pitches on Wednesday. That gap is where arm injuries happen.

Bullpen Report was built to close that gap. Here is what it does.

Cross-Team Pitch Count Tracking via BR Player ID

Every pitcher in Bullpen Report gets a permanent BR Player ID — a unique code like BR-RVUMYE that follows him across teams, seasons, and years. When a coach adds a player to their roster using his BR Player ID, pitch counts from every other team automatically become visible. No coordination between coaches required. No phone calls. No shared spreadsheets.

Every outing — regardless of team, league, or location — goes into one log tied to the pitcher, not a single roster. The moment a coach logs an outing, ARM STATUS updates immediately for every coach who has that player on their roster.

ARM STATUS: Know Who Can Pitch Before You Write the Lineup

Every pitcher in Bullpen Report has a real-time ARM STATUS: green (good to pitch), yellow (monitor load), or red (rest required). The status calculates automatically from every outing across all teams using the official MLB Pitch Smart guidelines.

Logging an outing takes under 30 seconds: date, pitch count, innings pitched. Advanced stats like ERA, WHIP, strikeouts, and walks are available but optional — they never get in the way of tracking arm health.

Rest Day Calculations Based on MLB Pitch Smart Guidelines

Bullpen Report uses the official MLB Pitch Smart guidelines as the source of truth for every rest day calculation. Pitch Smart is Major League Baseball's youth pitching safety program, developed with USA Baseball and the American Sports Medicine Institute. Little League, USSSA, Perfect Game, and most travel organizations reference these same guidelines.

A 10-year-old who throws 66 or more pitches needs four full calendar days of rest. A 12-year-old who throws 51 to 65 pitches needs three days. Bullpen Report calculates this automatically and shows the exact date your son is cleared to pitch again.

Game Day Report: AI Pitching Plan Before Every Game

For coaches, Bullpen Report generates an AI-powered Game Day Report before each scheduled game — a pitching plan showing which pitchers are available, who is resting, how many pitches each available arm has thrown this week, and a suggested usage order based on workload and rest. No more guessing at the field.

Load Management: Spot Overuse Before It Becomes an Injury

The Load Management report shows a weekly heatmap of every pitcher's workload across the past several weeks. Coaches can see patterns a single-game view would never reveal — a steady increase in weekly pitch totals, shortened rest windows, or a pitcher who has been working too hard heading into tournament weekend.

ACWR Workload Monitoring

Bullpen Report calculates the Acute-to-Chronic Workload Ratio (ACWR) for every pitcher — the same metric used by professional sports organizations to monitor athlete injury risk. It compares recent workload (last 7 days) to long-term baseline (28-day average). When the ratio climbs above 1.5, injury risk spikes sharply. The ACWR sweet spot — 0.8 to 1.3 — means a pitcher is working hard enough to develop without overloading his arm.

Advanced Pitching Analytics

For coaches and parent Pro accounts, Bullpen Report tracks a full suite of advanced pitching stats calculated automatically from logged outings: ERA, WHIP, strikeout rate, walk rate, strike percentage, pitches per inning, Game Score, FIP, and projected season totals. Every metric includes age-adjusted thresholds — so you know whether a 47% strike rate is concerning for a 9-year-old, rather than comparing it to a major league standard that means nothing at youth level.

Who Bullpen Report Is For

Bullpen Report is built primarily for coaches who want visibility into their pitchers' full workload before making lineup decisions — not just what happened in their own games. One coach = 10 to 20 connected parents automatically.

It is also built for parents of youth pitchers who play for more than one team. The parent experience is always free: ARM STATUS, rest calendar, pitch history, and the ability to log outside outings — lessons, showcases, and bullpen sessions coaches would not otherwise see.


Track your pitcher's pitch counts across all his teams.
