Park Factors

A park factor of 1.00 means league-average for that metric. 1.18 means hitters HR (or get extra-base hits, or get hits) 18% more often there than at an average park. 0.92 means 8% less often.

Park factors reflect ballpark only — weather is shown separately and not included in these values.

Three Metrics

HR— home run rate. XBH— extra-base hit rate (2B + 3B + HR). HIT— total hit rate (1B + 2B + 3B + HR).

Splits

Toggle between All Hitters, vs RHH, or vs LHH. Splits use hand-specific league denominators, so a LHH-friendly park (Yankee Stadium short porch) shows up clearly — not buried under combined averages.

Why Numbers Look Conservative

Early-season factors get pulled toward neutral (1.00) until enough data accumulates. A genuinely +25% HR park will display as +13% in April and drift toward +25% as the season progresses. This avoids small-sample inflation that misleads users.
