Progressive Field Park Factors 2026

Progressive Field opened in 1994 and has hosted Cleveland Guardians home games for 32 seasons. The open-air second-generation modern ballpark seats 35,225 fans on grass a grass playing surface in Cleveland, OH. As an open-air park, weather is part of the matchup every game day. Wind direction, temperature, and humidity all materially shift HR probability and overall run-scoring environment, particularly during summer evening games.

Progressive Field plays as roughly neutral by park factor. Run factor (1.00) and HR factor (0.98) both sit near 1.00, meaning the venue alone doesn't systematically inflate or suppress offensive props. Pitcher matchup, batter form, and weather are the primary signals to evaluate at this park. These numbers come from multi-year MLB run-and-HR park factors and represent how the venue affects offensive output relative to a perfectly neutral park (factor 1.00). The further a park factor moves from 1.00, the more it should influence prop-line evaluation.

For prop bettors, here's how Progressive Field translates into actionable edges. Home run props at Progressive Field should be evaluated mostly on pitcher matchup and batter form rather than park factor. The venue is neutral enough that other variables dominate. Because Progressive Field is an open-air venue, always check weather before placing bets. Wind direction matters more than temperature: a 10+ km/h wind blowing toward center field can boost HR probability by 15-25% above the park's baseline factor, while wind blowing in can suppress HR probability by similar amounts.
