Stuff+ Leaderboards

Top pitchers by my model's 2025 Stuff+ grade, benchmarked pitch-by-pitch against FanGraphs' Stuff+. Grades reflect physical pitch characteristics only — velocity, movement, spin, release, and approach angle — independent of location, count, and batter handedness. 100 = MLB average.

Reading this page: each pitcher is ranked by my model's grade for that pitch type. FanGraphs' grade and rank are shown alongside for comparison. The right-hand block is the pitcher's actual 2026-season performance, for context on whether the grade is holding up.

Legend. My Stuff+ and FanGraphs grades are for the 2025 season (100 = league average; higher is better). Rk = the pitcher's rank within that pitch type on each system. The 2026 season block — IP, ERA, whiff rate, and xwOBAcon (expected weighted on-base average on contact; lower is better for the pitcher) — is live-season performance, not an input to the grade. † whiff rate and xwOBAcon are specific to that pitch type; IP and ERA are overall.

Coverage. This page currently shows 4 of the model's 7 pitch types (Four-Seam, Changeup, Slider, Splitter) with the top 10 pitchers each, transcribed from the model's validation set. Sinker, Cutter, and Curveball to follow.
