Fantasy Baseball 2025: The Impact of Changing Park Factors Around Baseball (Pt. 1)

(It’s fantasy baseball draft season! The FTN Fantasy team and a host of helpful guests present our Ultimate 2025 Fantasy Baseball Guide. Check it out and prepare for the 2025 MLB season.)

It’s the most wonderful time of the year.

The fantasy baseball content is starting to flow like eggnog, player pages on Statcast and Fangraphs are seeing more traffic than freeways on Christmas Eve, and we can find our friends in NFBC draft rooms or comparing rankings on our favorite fantasy baseball podcasts. However, as you begin researching to prepare to win your most important fantasy leagues in 2025, it is vital to uncover every square inch of the ever-changing baseball landscape, including new park effects.

We often evaluate park effects when a player gets traded because it’s intuitive to take their production in pitcher-friendly parks and transfer it to a more hitter-friendly environment. Who among us didn’t cringe when the Cubs acquired Isaac Paredes and plopped him into an environment with a unique wind factor and a much deeper left-field corner? Thankfully for Paredes, he has packed his bags yet again and is headed to Houston — an environment much more aligned with his hitting tendencies.

But trades aren’t always the only shifting factor. Sometimes the parks themselves change. Those changes are as important as players changing parks and can have just as big an impact. This article will address key park changes this offseason and how they might impact the market outlook on some of our draft targets and fades. This is the first part of my two-part series looking at park factor changes heading into fantasy drafts and the 2025 MLB season.
