What Are MLB Park Factors?
Park factors quantify how a stadium's dimensions, altitude, wind patterns, and climate affect offensive production. A power factor of 1.10 means that stadium produces 10% more home runs than a neutral environment. Run factors work the same way for total runs scored. Both are split by batter handedness (LHB vs RHB) because fence distances and wind patterns affect pull-side power differently for lefties and righties.
Hitter-Friendly Parks
Coors Field (Colorado) leads MLB with park factors well above 1.00 due to high altitude thinning the air. Great American Ball Park (Cincinnati) and Globe Life Field (Texas) also boost power production significantly. Target hitters in these parks for HR and total bases props.
Pitcher-Friendly Parks
Oracle Park (San Francisco) and Petco Park (San Diego) suppress home runs with deep fences and marine air. Comerica Park (Detroit) and T-Mobile Park (Seattle) also favor pitchers. Fade hitter props in these venues.
LHB vs RHB Impact
Asymmetric outfield dimensions create different park factors by handedness. A stadium with a short right-field porch boosts LHB power (pull side) while having minimal effect on RHBs. Always match batter handedness to the correct park factor column when evaluating props.
Using Park Factors for DFS & Betting
DFS Strategy
In MLB DFS, park factors are a core input for hitter projections. Stack hitters in parks with run factors above 1.05 — the extra scoring environment compounds when you roster 4-5 correlated hitters. Fade hitter stacks in pitcher-friendly parks unless the matchup against the opposing starter is overwhelming.
Prop Betting
For home run props, multiply a hitter's baseline ISO by the park's power factor. For total bases props, the run factor is a better proxy since it captures doubles and triples as well. Always check the handedness-specific column — a lefty in a LHB-friendly park has a larger edge than the overall factor suggests.

Data Source & Methodology
Park factors are calculated from historical game data and updated seasonally. Factors reflect multi-year averages to smooth out year-to-year variance.
Frequently Asked Questions
- What is a park factor in baseball?
- A park factor measures how a stadium affects offensive production compared to a neutral environment. A factor of 1.00 is neutral; above 1.00 means the park boosts that stat (hitter-friendly), below 1.00 means it suppresses it (pitcher-friendly). Factors are split by batter handedness because asymmetric field dimensions affect lefties and righties differently.
- What is the difference between power factor and run factor?
- Power factor measures a park's effect on home runs specifically — how many more or fewer homers are hit there vs average. Run factor measures the overall effect on runs scored, which includes singles, doubles, triples, walks, and errors in addition to home runs. A park can have a high power factor but moderate run factor (or vice versa) depending on its dimensions and climate.
- Which MLB parks are most hitter-friendly?
- Coors Field (Colorado Rockies) is by far the most hitter-friendly park due to high altitude reducing air resistance on batted balls. Great American Ball Park (Cincinnati), Globe Life Field (Texas), and Fenway Park (Boston) also consistently rate as hitter-friendly. These parks have power and run factors above 1.05.
- How do park factors affect DFS and prop betting?
- Park factors directly impact projected runs, home runs, and total bases. In DFS, stack hitters in parks with run factors above 1.05 for correlated upside. For prop betting, multiply a hitter's baseline power (ISO) by the park's power factor to estimate the true HR probability. Always use the handedness-specific column for the most accurate adjustment.
- Why are park factors split by batter handedness?
- Stadium dimensions are rarely symmetric — one outfield wall may be shorter than the other. A short right-field porch boosts left-handed pull power but has little effect on right-handed hitters who pull to left field. Splitting by LHB (left-handed batter) and RHB (right-handed batter) captures these directional effects accurately.
