How to use MLB ballpark factors for DFS
Ballpark factor measures how much a stadium inflates or suppresses offense relative to an average MLB park (100 = perfectly neutral). A factor of 115 means the park produces 15% more offense than average — making it significantly better for stacking hitters and worse for rostering pitchers. A factor of 86 means the park suppresses offense by 14% — ideal for a pitcher but poor for hitter stacks.
Coors Field is the most extreme park in baseball at 132+ due to the high altitude in Denver — the thin air reduces drag on batted balls, resulting in significantly higher HR rates and more offense than any other park. On the other end, Petco Park and Oracle Park consistently rank among the most pitcher-friendly environments in the sport.
Use park factors as a confirming signal alongside Vegas implied totals and BvP matchup data. A hitter with a strong matchup in a hitter-friendly park with a high implied total is a three-layer conviction play.
