Minor League Park Factors 2019

This document compiles park factors for all 14 minor leagues and 160 affiliates above the Rookie complex level.

Included are all classifications from Triple-A down to Rookie advanced. Excluded are the Arizona, Dominican Summer and Gulf Coast leagues.

Park factors are included for runs (Runs), home runs (HR) and batting average on balls in play (BABIP). The factors are expressed as multipliers, where 1.000 is average, that have been halved in magnitude to reflect the fact that players compile only half their statistics at their home parks.

Beside each park factor multiplier is a percentile score (%tile) to place each park in an overall minor league context. Each park is assigned a percentile score on a scale of zero to 100 based on how many runs, home runs or hits on balls in play are recorded at that park compared with the home results for the entire sample of 160 parks.

In other words, use Runs, HR and BABIP for calculations. Use the %tile to inform perceptions of how parks play. Do they favor hitters or pitchers or are they neutral?
