GoalTrax / LaxTrax
The first analytics platform that measures not just whether a goalie stopped the shot — but how. Built for coaches, recruiting coordinators, and athletes who want data that reflects what actually happened on the field.
The Problem
A goalie who faces 20 shots in a tight, defensive game and a goalie who faces 20 shots in an open, scrambling game look identical on the stat sheet. Save percentage treats every shot the same — it doesn't know if the shot came from 2 yards or 12, whether it was on-cage or barely on frame, or whether the defense created the stop before the ball was even released.
It rewards luck and punishes circumstance. And for decades, it's been the only tool coaches, recruiting coordinators, and families have had to evaluate goalie performance.
GoalTrax was built to fix that.
The Solution
GoalTrax measures goalie performance through GIx — the GoalTrax Impact Score. GIx goes beyond whether the shot was stopped. It measures how it was stopped. Did the goalie catch the ball and clear possession, or give up a dangerous rebound? Did they contain a fast break, or surrender one? Every shot result carries a different impact — and GIx captures all of it.
GIx is built on Expected Goals (xG), a shot-quality model that weighs location, distance, and context. But where other analytics stop at "saved or not," GIx continues: it scores the possession outcome of every save, every goal, and every off-target shot — giving coaches a true picture of a goalie's impact on the game.
Derivative stats — Clean Save %, Danger Rebound Rate, and Fast Break Rate — give coaches even more granular tools to develop, evaluate, and recruit with confidence.
"Two goalies. Same save percentage. Completely different GIx. Now you know who actually controlled the game."
— The GoalTrax InsightThe Platform
GoalTrax is live on the web and on iOS — available now at app.goal-trax.com and in the App Store. It supports both men's and women's lacrosse with distinct field geometry, xG models calibrated to each game, and position-specific inputs.
Chart shots in real time. GIx scores every play — catches, clears, fast breaks, and rebounds — and generates coaching narratives that explain exactly what happened and why it mattered. Headline stat plus Clean Save %, Danger Rebound Rate, and Fast Break Rate. Men's and women's modes.
AttackTrax applies the same Expected Goals framework to shooters. GAAx — Goals Added Above Expected — tells you which attackers are producing above the quality of their looks. Same rigor, offensive lens.
Who It's For
Evaluate your goalies and opposing shooters on the merit of their performance — not the performance of the team around them. Coach smarter with data that actually differentiates.
Make offer decisions with data that cuts through the noise. GIx tells you what the eye test only hints at — and what save percentage completely misses.
Chart your own games. Build a verified performance record over time. Let the numbers make the case for you — to coaches, to programs, and to recruiters who are looking for the real thing.
