MLB Park Factors 2026: Stadium Stats & Data

This page lists the three-year rolling “MLB park factors” for every 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.

Why MLB Park Factors Matter for Betting
Knowing the city and ballpark is crucial for MLB betting for several reasons. Below, I will explain the most-significant implications.
Hitter-Friendly and Pitcher-Friendly Parks
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.
Park 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 and 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 and Weather 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.

A park factor is a metric used to evaluate how a specific stadium’s unique dimensions, altitude, and weather conditions impact offense compared to other stadiums around the league. Because baseball fields do not have uniform dimensions like football fields or basketball courts, some parks naturally favor hitters, while others favor pitchers. A baseline of 100 represents a completely neutral environment.
MLB park factors are calculated by comparing the rate of runs scored (and allowed) by a team and their opponents at their home stadium versus the rate of runs scored (and allowed) when those same teams play on the road. The formula is typically adjusted for sample size and team quality over a multi-year rolling period to isolate the stadium’s actual physical influence from a hot or cold offense. A park factor above 100 indicates a hitter-friendly environment, while a rating below 100 favors pitchers.
Historically and consistently, Coors Field – home of the Colorado Rockies – is the most hitter-friendly ballpark in MLB. The stadium’s high altitude in Denver means the air is thinner, causing baseballs to travel further and breaking pitches to break less. Other perennially hitter-friendly parks include Boston’s Fenway Park and Cincinnati’s Great American Ball Park.
Yes, park factors are crucial for MLB betting, especially when handicapping Over/Under (totals) and prop bets. Smart bettors use park factors to identify value when standard betting lines don’t fully account for a stadium’s environment—such as a fly-ball pitcher moving from a pitcher-friendly park to a hitter’s haven. It is also an essential tool for evaluating true player performance in Daily Fantasy Sports (DFS).
