Guaranteed Rate Field
MLB ballpark HR park factor + handedness splits
Why this park plays this way
White Sox home. Slight HR boost across both handedness sides, with LHB very marginally preferred. Chicago summer humidity adds carry. Wind off Lake Michigan can blow in (suppresses) or out (boosts) — check pregame wind direction.
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.
