Read the numbers
Every main score is scaled so 100 = league average for a pitcher's role, with higher = better. Here's what each one measures.
The 100 scale
COLD · AVERAGE · HOTUse several scores together. Great stuff with poor results — or the reverse — is exactly where the interesting analysis lives.
Composite Score
THE HEADLINE NUMBERA single overall grade blending results, pitch quality, and command into one number. It's the quickest way to compare arms — a starting point, not the whole story.
Stuff+
110+ PLUS · 120+ ELITEPhysical pitch traits — velocity, movement, spin, and shape measured against peers. "How nasty does the arsenal look on paper?"
Predictive Stuff+
Stuff+ with extra weight on high-leverage pitches — late counts, close games, runners on base. Rewards the arms that bring it when it matters most.
Command+
Location quality — working the edges, avoiding middle-middle, and executing the plan pitch after pitch.
Performance+
Actual batter outcomes — strikeouts, walks, contact quality, and damage allowed, all situation-weighted. "How has he actually been getting outs?"
Health Score
One simple durability grade: how much a pitcher is healthy and taking the ball, combined with how steady he is start to start. Higher means an arm you can count on.
Availability
How many innings a pitcher actually throws compared to what's expected of his role. It only counts from his first game up, so a late call-up isn't dinged for time before he arrived.
Consistency
How stable a pitcher's results are outing to outing — steadier arms score higher.
In the Trend Builder, Health also breaks out into Season, Recent, and Career views. Splits Metrics add pitch-level inputs like VAA, extension, arm angle, zone score, shadow% and chase%.
