Do You Know The Easiest and Hardest MLB Homerun Parks?

Why 2025's Park Factors Matter More Than You Think

If you follow the business of baseball, you already know ballparks are more than scenery. They're economic engines, brand statements, and - thanks to Statcast - quantifiable environments that shape how front offices evaluate talent and allocate payroll.

And in 2025, Statcast's home run park factors told a fascinating story.

A quick refresher:
A park factor of 100 = league average.
Anything above 100 = easier to hit a home run.
Anything below 100 = tougher to clear the fences.

And yes - Statcast calculates for who is hitting and pitching, plus their handedness, by comparing their performance in the selected park vs. everywhere else. So Coors Field's 115 HR park factor doesn't mean the Rockies hit 15% more homers at home. It means that hitters and pitchers from any team saw 15% more home runs when games happened at Coors vs. the rest of the league.

With that foundation, let's look at the extremes - and the full ranking.

The Easiest Home Run Parks of 2025

Some parks give the baseball a little extra life. Elevation, dimensions, weather patterns, and ballpark architecture all play roles. In 2025, three stadiums stood out:

1. Coors Field - Rockies (115)

Altitude wins again. Coors remains baseball's ultimate HR accelerator.

2. Sutter Health Park - Athletics (108)

The A's temporary home turned into a surprising launching pad.

3. Comerica Park - Tigers (105)

Traditionally pitcher-friendly, 2025 flipped the script with a HR factor spike.

The rest of the above-average group:

• Dodger Stadium (104)

• Fenway Park (103)

• Rogers Centre (103)

• Oriole Park at Camden Yards (103)

• Chase Field (102)

• Citizens Bank Park (102)

• George M. Steinbrenner Field (102)

• Nationals Park (101)

• Truist Park (101)

• Angel Stadium (101)

• Target Field (101)

Middle-of-the-Pack Parks: Close to Neutral

These parks hovered near the league baseline - neither helping nor hurting long balls by much.

• Great American Ball Park (99)

• Yankee Stadium (99)

• Oracle Park (99)

• Citi Field (99)

The Toughest Home Run Parks of 2025

Some parks swallow baseballs whole. Outfield depth, marine air, and architectural quirks can turn certain stadiums into pitcher-safe havens.

Hardest of the Hard: Globe Life Field & T-Mobile Park (91)

Globe Life Field (91) and T-Mobile Park (91) were the least HR-friendly environments in MLB for 2025. If you were slugging there, you were earning every inch of it.

Other parks below league average:

• Rate Field (98)

• American Family Field (98)

• Wrigley Field (98)

• Daikin Park (97)

• loanDepot park (97)

• Busch Stadium (97)

• Kauffman Stadium (97)

• PNC Park (96)

• Progressive Field (95)

• Petco Park (95)

What These Park Factors Mean for Teams, Players, and Front Offices

Park factors aren't just a line on a leaderboard - they're a force multiplier in how baseball organizations make decisions, spend money, shape strategy, and build their identity. Here's how teams actually use this data inside the building:

Roster Construction: Building a Team That Fits the Address

Teams aren't assembling rosters in a vacuum. A club in a homer-friendly environment like Coors or Sutter Health Park can justify investing in slug-first bats that might be undervalued elsewhere. A club living in a run-suppressing space like T-Mobile Park has to think differently - prioritizing gap hitters, rangy outfielders, and pitchers who force contact that stays in the yard.

Executives aren't guessing. Models run thousands of simulations with park factors baked in. Contract decisions, arbitration projections, and does this guy actually work here? conversations all flow through that lens.

Player Valuation: Not All Home Runs Are Created Equal

A 25-homer season in a pitcher-heavy environment is not viewed the same as 25 in a power haven. Park factors help front offices normalize production and strip out the stadium bias. That's why players coming from suppressed parks often get a valuation bump - their numbers say one thing, but the context says more.

Teams use this to buy low on hitters trapped in environments that don't match their skill set, and to protect themselves from overpaying players who benefitted from the stadium doing some of the lifting.

Marketing & Fan Engagement: The Business Case for a Stadium's Personality

Ballpark identity is a brand asset. A reputation for fireworks (Coors, Fenway, Sutter Health Park) drives ticket demand, premium seating pricing, sponsor activations, and broadcast hooks. Even the way teams tell their stories shifts: a club in a power-friendly environment can highlight "big fly" energy; a club in a pitcher-forward environment leans into defense, precision, and tense late-game strategy.

Park factors shape expectations, and expectations shape revenue.

Scouting & Development: Evaluating Talent Through an Honest Lens

Player development departments lean on park-adjusted metrics to assess whether a prospect's numbers reflect skill or scenery. A hitter posting modest power in a tough HR environment might grade out higher than a slugger in a stadium that inflates long balls. Pitching departments use park factors to understand how much to trust a young arm's HR suppression or whether he's benefiting from design-friendly confines.

For clubs building through the system - which is most of MLB - this information helps avoid misallocating years of development resources.

The Bottom Line: Park Factors Fuel the Business Behind Baseball

These numbers aren't trivia. They ripple through roster models, payroll planning, contract negotiations, lineup strategy, and even storytelling. Park factors shape how teams operate - on the field and inside the front office.

How to Read Park Factors (Checklist)

1. Look for Trends Across Seasons

A single-season spike - like Comerica's - might signal conditions or adjustments worth watching.

2. Focus on Extremes First

Lopsided home/road splits often start with park environment.

3. Consider Player Handedness

Statcast bakes this in, but it's still useful when evaluating hitters who thrive in specific pull-friendly parks.

4. Apply Context to Player Contracts

Agents and teams negotiate with park factors very much in mind.

Park Factors Shape the Game Behind the Scenes

The 2025 park factor leaderboard is more than a fun ranking - it's a blueprint for how teams make decisions, how player performance is interpreted, and how the economics of baseball move beneath the surface.

If you're tracking the business side of the sport, these numbers give you an edge.
