The impact of park factors on players’ fantasy baseball value is no longer a secret. However, not everyone is aware of the most recent park-factor developments.

For instance, one Major League Baseball (MLB) ballpark has undergone offseason renovations, and two teams will play in temporary homes in minor-league parks this year. Correctly anticipating how those parks will play in 2025 is one edge gamers can take into fantasy baseball drafts. Additionally, knowing which ballparks are at the extreme ends of the spectrums for homers and scoring is also a critical consideration.

2025 MLB Park Factors Overview

Let’s dive into the various park factors across MLB in 2025 that will impact fantasy baseball.

Ballpark Renovations and Changes for 2025

Oriole Park at Camden Yards (Orioles)

Oriole Park at Camden Yards has been a hitter-friendly environment for most of its existence. However, since changes were made to the dimensions before 2022, it’s shifted to a pitcher-friendly venue. According to our three-year data, Oriole Park at Camden Yards had park factors of 0.938 for runs and 0.908 for homers. Moreover, among MLB’s ballparks still in use with data during that span, righties had the lowest park factor for homers (0.713). The second-lowest and third-lowest park factors for homers were 0.765 at Oracle Park in San Francisco and 0.825 for Progressive Field in Cleveland.

Right-handed batters can breathe a sigh of relief entering the 2025 season. Oriole Park at Camden Yards has moved the left-field wall in and lowered the fences in places, attempting to find a happy medium between the pre-2022 hitter-friendly conditions and the 2022-2024 pitcher-friendly conditions.

Sutter Health Park (Athletics)

The Athletics will call Sutter Health Park in Sacramento their temporary home while constructing their new ballpark in Las Vegas. Sadly, I’ve been unable to find ballpark factors that include 2024. Yet, Baseball America had park factors using a two-year sample from 2022-2023. The following table has Baseball America’s ballpark factors for that period, using Baseball Savant’s template of setting neutral factors to 100. Every point above or below represents a 1% difference relative to the occurrence happening at all other ballparks.

George M. Steinbrenner Field (Rays)

Sadly, Tropicana Field suffered significant damage during Hurricane Milton, displacing the Rays for 2025. They'll play games in Tampa at George M. Steinbrenner Field, the spring training home for the Yankees and the minor-league ballpark for their Low-A affiliate. Like Sutter Health Park, George M. Steinbrenner Field had park factors for 2022-2023 available at Baseball America. The following table has those park factors.

In addition to the change in park factors for the Rays, it's worth noting they'll play home games outdoors this season.

Run-Amplifying Parks (5% or Greater Increase in Run Scoring)

Coors Field is MLB's highest run-scoring venue by a lot, which shouldn't surprise anyone. That's not a recent development. Interestingly, the once pitcher-friendly loanDepot park in Miami has swung from a pitcher-friendly park in its early years to the second-highest scoring park after not cracking the top five in the 2024 overview.

Fenway Park has slipped from second in the 2024 park factors overview to fourth, Great American Ball Park dipped from third to fifth and Kauffman Stadium climbed from fourth to third. In addition, Globe Life Field fell out of the ballparks that enhance runs by 5% or more, and PNC Park joined the mix.

Run-Suppressing Parks (5% or Greater Reduction in Run Scoring)

PETCO Park was the lowest-scoring park entering last year and climbed to the second-lowest because T-Mobile Park slipped from the third-lowest to the basement. Citi Field is still in this section but has a slightly better park factor for runs entering 2025 (0.913) than entering 2024 (0.873).

Wrigley Field is a newcomer in this section, which is a massive change since it has the third-lowest park factor for runs, depressing them by over 10% after not reducing runs by even 5% before 2024. Oracle Park and Dodger Stadium are holdovers from last year. Tropicana Field and the Oakland Coliseum were on last year's table but won't host games this year.

Busch Stadium and Progressive Field were in this section last year but aren't among the lowest-scoring venues this year. Finally, Oriole Park at Camden Yards' park factors should be taken with a grain of salt since they adjusted the dimensions, as noted above.

Homer-Amplifying Parks (10% or Greater Increase for Homers)

Like Coors Field in the highest-scoring ballparks section above, Great American Ball Park is unsurprisingly atop the table for homer-amplifying ballparks. Great American "Small" Park was also MLB's top launching pad entering last season. Great American Ball Park and Coors Field are the only ballparks that enhance runs by at least 5% and homers by at least 10%.

Globe Life Field fell out of the highest run-scoring ballparks this year but retained a spot in this section. American Family Field, Angel Stadium and Yankee Stadium are also holdovers from this section of last year's piece. Guaranteed Rate Field (1.176 for homers entering last year) fell out of this section. Dodger Stadium is also a holdover from this section in 2024. However, they warrant special attention as one of MLB's most significant run-suppressing ballparks while simultaneously enhancing dingers.

Finally, Citizens Bank Park didn't boost bombs by at least 10% entering 2024. Yet, it's back after a one-year hiatus since it was in this section in 2023.

Homer-Suppressing Parks (10% or Greater Reduction for Homers)

Chase Field and Oracle Park are in a class of their own for keeping the ball in the park. The former was in the basement last year, too. The latter had the third-lowest park factor for homers before 2024, but the Oakland Coliseum had the second-lowest but won't host games this season.

Wrigley Field has the dubious distinction of joining the lowest-scoring ballpark table after not appearing in either section last year. Gamers should adjust their expectations for scoring and homers at Wrigley Field.

Meanwhile, PNC Park and Kauffman Stadium are the inverse of Dodger Stadium. While Dodger Stadium is a pitcher-friendly park that increases taters, PNC Park and Kauffman Stadium are hitter-friendly venues that decrease dongs.
