Minor League Park Factors At Midseason 2021

New leagues. New scheduling. A number of new affiliates and ballparks.

The 2021 season has ushered in a new era of the minor leagues. To help make sense of the newness, we present park factors for the 120 full-season minor league parks at midseason.

These park factors are basic comparisons of home output and away output, expressed as both an index (PF) in which 100 is average and a multiplier (Mult) that halves the impact of the park factor to reflect that players play only half of games at home. The statistics being compared are runs, home runs and batting average on balls in play.

These factors are intended to be estimates. However, they are subject to more distortion than usual because of variables unique to 2021, including uneven quality of play and scheduling that is not as varied as usual.
