Reading park factors

Each factor compares a stat per plate appearance in a team's home games (both teams batting) with the same team's road games. 100 is neutral; 110 means 10% more of that stat at this park. Three seasons together give a steadier number than one. The run factor column is the one used for this season's park-adjusted numbers such as wRC+; it uses earlier seasons only.

Free and members. The three-season table is free. Single-season factors are part of Analytics, and every higher plan includes them.
