What the Pitch Was Doing Compare

Two Arms,
Side by Side

Pick any two of the sixteen arms. Every bar shares one scale across the gutter, so a longer bar is genuinely more; the badges flag each arm against the league line. No live query, no fabricated head-to-head winner - just two readouts you can line up yourself.

Bars share one scale per row across both panels. Badges compare each arm to the league line (lower xwOBA and lower run value are better for the pitcher). Velo, spin, whiff, xwOBA and run value are real Statcast figures; Stuff+ is a Curated stand-in from the real velocity and whiff inputs - see the methodology on the front page.
