Why this park plays this way
Famously wind-dependent. When wind blows out, scores explode. When wind blows in, fly balls die. Day games are a different park than night games.
How to use park factor when betting MLB
Park factor is one of 12 factors in our HR model. It carries roughly 11% of total weight in the default profile — material, not dominant. Other big factors: batter power, batter Statcast quality, opposing pitcher HR vulnerability, weather.
For most parks, factor doesn't override a weak pitcher matchup — but extreme parks (Coors at 118, Oracle at 88) can swing a player's projected HR rate by 5+ percentage points. Pair an elite power bat with the right park and you're looking at our top 5 every time.
