Is Chase Field a Hitters Park?
Yes. Chase Field is a hitters park. It scores 6% more runs than an average MLB park and allows 12% more home runs.
2026 park factors, three-year rolling averages. 100 = league average.
Why Chase Field plays this way
Dry desert air and a huge outfield — a humidor tamed it, but it still favors hitters.
Home of the Arizona Diamondbacks in Phoenix, AZ, opened in 1998.
What a park factor actually means
A park factor of 106 means runs are scored 6% more often here than at an average MLB park — comparing the same teams at home and on the road, so roster quality cancels out. The home run factor of 112 does the same thing for home runs only.
The two can disagree sharply, and that is the useful part. A park can suppress home runs while inflating runs, if the wall that stops fly balls also turns them into doubles. Read both numbers before deciding what a park does to a hitter.
