With all 30 teams adopting humidors (previously I think it was just five?) this year I've been curious whether that might impact home runs. While a humidor helps control the environment that ball is stored in, it can both improve or decrease how the ball performs relative to a ball not stored in a humidor (based on alternate storage methods and atmospheric conditions at each individual site). My sense is that in Milwaukee a humidor may deaden the ball a bit, but I don't know that to be fact.
Historically Miller Park/AmFam Field has been considered an "offensive friendly" ballpark, but that's really been boosted by the home run outputs there (above league average every year since 2009). For the past several years it has actually played below average in terms of all other types of hits (singles, doubles, triples). There have only been three parks that have suppressed doubles more than AmFam Field since 2019 (White Sox, Mariners, Yankees).
It seems as though if you significantly reduce the home runs at AmFam Field you'll likely end up with a pitcher friendly ballpark.
