MLB Park Factors

This page details the 3-year rolling “park factor” for every MLB stadium in the league, i.e. how many runs have been scored, on average, at each park over the past three seasons. The list can be ordered by overall scoring, home runs (including by left-handed and right-handed hitters), extra-base hits, over percentage, and more.

Knowing the city and ballpark is crucial for MLB betting for several reasons.

Park Factors: Every ballpark plays differently. Coors Field in Denver is the most extreme example – the high altitude and thin air dramatically inflate offense, making overs much more attractive. Meanwhile, parks like Petco Park in San Diego or Oracle Park in San Francisco are known as pitcher-friendly environments that suppress scoring.

Dimensions and Layout: Some parks have short porches (Yankee Stadium’s right field, Fenway’s Green Monster) that favor pull hitters, while others have deep power alleys that kill home runs. Knowing the park dimensions helps you assess whether a team’s offensive profile matches up well with the venue.

Roof/Dome Stadiums: Parks like Globe Life Field (Texas), Rogers Centre (Toronto), and Tropicana Field (Tampa Bay) have retractable or fixed roofs, meaning weather is essentially irrelevant for those games. This is critical – you won’t get a weather edge betting those games.

Wind Patterns: Certain open-air parks are notorious for wind, particularly Wrigley Field in Chicago, where the wind direction is one of the most closely watched factors in MLB betting. Other coastal parks like Oracle Park can have consistent wind patterns that affect ball flight.
