01 / Interpretation

What this measures

Positive values mean the separately denominated S-event rate is numerically larger than the in-zone rate in that count; it is a broad outcome-zone proxy rather than a same-base event difference or swing-decision metric.

02 / Calculation

descriptive gap = separately denominated strike_rate_type_S - in_zone_rate; top-pitch share = top_pitch_pct / 100

Use the table to inspect available fields and the source JSON to trace the formula inputs. CSV percentage values are stored as fractions.

03 / Population & limits

Twelve legal pre-pitch counts in the local 2025 Statcast pull; each row retains its published raw count n.

The S event includes called strikes, swinging strikes, and fouls, so the gap is not chase rate. S-event and in-zone rates use separate non-null denominators (n_type and n_zone), which are not exposed in these rows; the difference is therefore a descriptive proxy. Top-pitch share uses the count's classified-pitch denominator.
