Park factors have long been a meaningful consideration in player rankings and day-to-day expectations throughout the grind of the fantasy baseball season. However, park factors change, and it’s critical to review them annually to assess new ballparks, renovated ballparks and outliers in scoring and homers.

2026 MLB Park Factors Overview & Fantasy Baseball Targets
Let’s dive into the various park factors across MLB in 2026 that will impact fantasy baseball.
Ballpark Renovations and Changes for 2026
Kauffman Stadium (Royals)
Kauffman Stadium is making sizable renovations before the 2026 season, moving the walls in and making them shorter. The goal is to enhance home runs. According to our three-year park factors, Kauffman Stadium was tied for the third-highest park factor for runs (1.064), but it had the eighth-lowest park factor for homers (0.913).
Homers will almost certainly rise in 2026 because of the renovations. Ben Clemens took a more detailed look at the new dimensions and 2026 expectations for Kauffman Stadium for FanGraphs.
2025 Renovated Ballparks and New Ballparks Review
Oriole Park at Camden Yards (Orioles)
The renovations to Oriole Park at Camden Yards before the 2025 season turned it into a launching pad. According to Baseball Savant’s 2025 park factors, Oriole Park at Camden Yards was tied for fifth in park factor for runs and second for home runs. It should be treated as one of MLB’s best hitting environments again in 2026.
Sutter Health Park (Athletics)
My expectation for how Sutter Health Park would play in 2025 was one of my biggest whiffs. The Baseball America ballpark factors for Triple-A ballparks demonstrated Sutter Health Park in Sacramento had pitcher-friendly hitting conditions relative to other Triple-A parks. Of course, scaling ballpark factors relative to other minor-league parks is different than comparing them to MLB stadiums.
Sutter Health Park was a mouthwatering venue for offense in 2025. According to Baseball Savant’s park factors, it had the second-highest park factor for runs, tied for the sixth-highest for homers and boosted singles and doubles as well. Gamers should be excited to have hitters playing at Sutter Health Park in 2026.
Run-Amplifying Parks (1.050 or Higher)
Coors Field remains in its perch atop MLB’s highest-scoring ballparks. Sutter Health Park and Kauffman Stadium were analyzed above. Target Field and Comerica Park are new to this section. Fenway Park, Great American Ball Park and PNC Park fell out of this section, and loanDepot park is a holdover from the 2025 overview.
Run-Suppressing Parks (0.950 or Lower)
T-Mobile Park retains its standing as MLB’s lowest-scoring ballpark. Petco Park, Wrigley Field and Oracle Park were in this section last year, but Citi Field, Oriole Park at Camden Yards and Dodger Stadium fell off this table.
Homer-Amplifying Parks (1.100 or Higher)
Gamers chasing dingers when drafting or streaming should take note of the six stadiums on the table. Great American Ball Park had the top park factor for enhancing homers last year, and it’s still atop the heap this season. The other five stadiums on the table are holdovers from last season. Dodger Stadium and Citizens Bank Park climbed to second and third, respectively.
Homer-Suppressing Parks (0.900 or Lower)
The six ballparks on the table are where homers go to die. Fly-ball pitchers are more intriguing in the half-dozen ballparks on the table, as it will be more difficult to take them yard at these parks. Chase Field, Oracle Park, PNC Park and T-Mobile Park are carryovers. Busch Stadium and Fenway Park should be filed under “new additions” as challenging places to hit home runs.
