Sector factor
Outcome rate in one field sector vs the league baseline for that sector. 100 = average.
What Sector factor means
Splits the outfield into left, left-center, center, right-center and right, then compares this park's rate of the chosen outcome in each wedge to a league baseline built from the same batted balls. Isolates a short porch or a deep alley that whole-park factors average away.
What counts as a good Sector factor
Higher is better — roughly 90 is poor, 100 average, 110 good, and 120 or better elite.
