Five most pitcher friendly
Five most hitter friendly
See the full hitter friendly rankingWhat makes a ballpark pitcher friendly
A pitcher friendly ballpark suppresses offence relative to the league average. The drivers are the same ones that make a park play big, running the other way: deep outfield distances, tall walls, large foul territory, low elevation and heavy, cool air that keeps the ball from carrying. A deep power alley turns a ball that leaves the yard elsewhere into a routine fly out, and generous foul territory converts foul pops into extra outs that a cramped park gives back to the hitter. This ranking covers all 30 MLB home ballparks only. Neutral-site and temporary venues are excluded so the ranking compares like with like.
Index 100 is league average. Anything below 100 favours the pitcher. The lower the home run index, the harder it is to hit the ball out of that park for the handedness you have selected.
Why a park can favour pitchers against one handedness only
Outfields are rarely symmetric, so a park can suppress right-handed power while playing neutral or even generous for left-handed power. A deep left field punishes righty pull hitters and leaves lefties untouched. That is why a single combined park factor is misleading for lineup decisions, and why this page defaults to one handedness and lets you toggle.
Check the split that matches the pitcher you are considering. A right-handed starter faces a lineup that is usually majority right-handed, so the right-handed split is the one that carries most of the weight for him.
How to use this for DFS and betting
Park factors are a slow moving, stable input. They are built from multiple seasons of batted ball data, so they do not swing week to week. Use them as a filter when you build a pitcher pool: a strikeout arm in a suppressing park has both a higher floor and a lower home run risk than the same arm in a launching pad.
Same day weather sits on top of that baseline and can move it. A pitcher friendly park with a strong wind blowing out plays closer to neutral for one night. Check today's wind before you lock a lineup, then layer it on the ranking you see here.
Run totals respond to the same input. A game in one of the bottom five parks on this list carries a lower expected total than the same two teams in one of the top five, all else being equal.
Frequently asked questions
Which MLB ballpark is the most pitcher friendly?
The park at the top of this table is the most pitcher friendly for the handedness and season you have selected, because the table is sorted by home run factor ascending. The answer changes by handedness and by season, so use the toggles rather than relying on a single ranking.
Which ballpark is the most hitter friendly?
Look at the bottom of this table, or open the hitter friendly ballparks page, which sorts the same data the other way. The park with the highest home run factor is the most hitter friendly for that split.
Do domes play pitcher friendly?
Not by themselves. A roof removes wind and temperature swings, so a dome plays close to its own baseline every night. Whether that baseline favours the pitcher depends on the dimensions of the park, not on the roof.
Do park factors change every year?
They move slowly because they are computed over multiple seasons. A single season figure early in the year is noisy on a small sample. The multi year number is the stable one, and a park can still shift a few places as new seasons are added.
Should I fade hitters in pitcher friendly parks?
Treat it as one input rather than a rule. A park factor of 92 is a meaningful trim on a hitter's home run equity, but it does not outweigh a large platoon edge or a very weak opposing pitcher. Use it to break ties inside a player pool.
