MLB Park Factors 2026
Park factors describe how each MLB ballpark inflates or suppresses offense relative to a neutral park (100 = league average). Higher numbers favor hitters; lower numbers favor pitchers. These are core inputs into every Diamond DFS projection.

How park factors affect DFS
A 110 runs park factor means the venue produces roughly 10% more runs than league average over a multi-year sample. For DraftKings MLB DFS that translates to:
- Higher hitter ceilings at Coors, Fenway, Great American, and Camden Yards.
- Cheaper hitter salaries relative to projection at suppressed parks like Petco, Oracle, and T-Mobile.
- Bigger pitcher edges (and bigger SP fades) at extreme parks in either direction.
Frequently asked
What is a park factor in MLB?
A park factor measures how much a ballpark inflates or suppresses run scoring compared to a neutral park. 100 is league average. Above 100 favors hitters; below 100 favors pitchers.
Which MLB park is the most hitter-friendly?
Coors Field in Denver is the most hitter-friendly park in MLB by a wide margin. The altitude reduces air density, which lets fly balls carry farther and breaking pitches move less.
Which MLB park is the most pitcher-friendly?
Petco Park in San Diego consistently ranks as the most pitcher-friendly park in MLB, with marine air, deep gaps, and historically suppressed home-run rates.
How does Diamond DFS use park factors?
Park factors are one input into the Diamond DFS projection engine. Hitter projections at hitter-friendly parks (Coors, Fenway, Great American) are boosted, and pitcher projections are reduced. The opposite is true at pitcher-friendly parks like Petco, Oracle, and T-Mobile.
