Hit probability vs. observed outcomes

Each graded hitter projection carries a pre-game hit probability. Grouping graded projections by that probability shows how often players in each band actually recorded a hit.

Method: projections are archived to tracking files before first pitch. After games complete, final box-score stats are written next to each archived projection. All figures on this page are computed from those files at page load — no re-modeling, no adjustments.

Some sports have deeper historical grading than others. We only publish metrics where current verified tracking is available.
