How to Read MLB Park Factors

A 1.00 factor is league average. A 1.10 home run factor means the park plays about 10% above average for home runs.

Run factor is best for totals context. Home run factor is best for power props. Hits factor is better for contact-oriented props.

Venue context should be paired with weather, lineups, pitchers, bullpens, and market price. It is not a standalone pick.
