What we can't say about Dillon Wilson
This season is 1,186 graded takes, which puts Dillon Wilson's overall accuracy at 95.3% ± 1.2 (95% interval). That interval is a large share of the whole league's four-point spread, so this grade is a reading and not yet a ranking — we print it, and we do not place it against umpires with a full season behind the plate. Everything finer is further out of reach still:
- how the zone moves with two strikes — about 237 takes, so ±2.7 points. (the league-wide two-strike effect is about 1 point in 2026.)
- any single corner of the zone — about 99 takes, so ±4.2 points. (corner cells are where umpires actually differ.)
- whether one pitcher is called tighter than another — about 20 takes, so ±9.3 points. (a given pitcher is worked once or twice a season.)
And a note on the number itself: an accuracy figure is a rate plus a convention for what counts as a miss. Ours grades every taken pitch against the rulebook zone as the feed reports it. Others are more forgiving — UmpScorecards counts a call wrong only when the pitch was at least 90% likely to be a strike — so two sites can print the same percentage about the same umpire and not mean the same thing by it. How the grade is built.
The overturn rate is a different kind of number and does not belong beside the grade: it is accuracy on the 22 pitches players chose to challenge, which are the pitches they already believed were wrong. At 22 challenges it is far too thin to rank at all — the interval is roughly ±19.5 points — so we print it beside its denominator and keep it off every leaderboard.
