Stuff+ leaderboard

Every MLB and Triple-A pitcher and pitch in 2026, graded on velocity, movement, and release alone.

Stuff+ grades a pitch only on physical traits the pitcher controls: velocity, movement, spin, release point, extension, arm angle, and how the pitch differs from his primary fastball. 100 is an average MLB pitcher and every 10 points is one standard deviation. RV+ is actual run value on the same scale, so you can see who got results their stuff doesn’t explain, and vice versa. How the model works and how well it predicts: Stuff predicts next season better than results do.

2026 regular season. Triple-A pitchers are graded on the same MLB-trained model, so their numbers are directly comparable with big leaguers’. Triple-A RV+ is measured against weaker hitters, so expect it to run high. How Stuff+ is built.
