Separation Score Leaderboard

What is Pitch Separation Score?

Separation Score measures how much a pitcher's pitches diverge at the plate using usage-weighted Euclidean distance. Pitch pairs are weighted by combined usage (geometric mean), so high separation between frequently-thrown pitches matters most. Think sinker/sweeper combos like Blake Treinen.

Elite (90+)

22+ inches of weighted separation - devastating arsenal

Good (70-90)

17-22" - strong pitch shape contrast

Average (<70)

<17" - pitches move similarly, easier to read

Horiz. and Vert. columns show weighted average separation in inches. Click any column header to sort.

For each pitch type pair in a game:

1. Calculate Euclidean distance: √((pfx_x₁ - pfx_x₂)² + (pfx_z₁ - pfx_z₂)²)

2. Weight by usage: weight = √(usage₁ × usage₂)

3. Sum weighted separations across all pairs

4. Divide by total weight for weighted average

5. Scale to 0-100: score = (avg_sep / 25) × 100

Best Pair = the pair with highest euclidean × weight product. pfx values are converted from feet to inches (×12). Season scores are averages of game-level calculations.
