Data quality warning: this game's Trackman PlateLocHeight reading ran
+0.75 ft off the season norm across the entire game (median
3.21 ft over 292 pitches) — a likely camera/
calibration drift for this game, not real pitch locations. This game is excluded from umpire accuracy
grading entirely; the chart below uses the raw (uncorrected) locations and is shown for reference only —
it should not be read as real missed calls.
Correct calls fade into small pale dots; missed calls are drawn large and outlined so the actual miss
pattern stands out, the same way Umpire Scorecards presents its zone charts. Height is normalized to that
specific batter's own strike zone (derived from their listed height) so batters of different heights can be
plotted against one shared zone box — 0 is the bottom of their zone, 1 is the top. The dashed outer box is
the "shadow zone" (~4 inches beyond the edge) — real misses cluster there; clear-cut pitches are almost
always called correctly. The red-tinted background is a miss-rate heatmap by location.
