Fenway Park

Fenway Park opened in 1912 and has hosted Boston Red Sox home games for 114 seasons. The open-air classic ballpark seats 37,755 fans on grass a grass playing surface in Boston, MA. 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.

Fenway Park plays as a mild hitter's park. With park factors of 1.04 (runs) and 1.01 (HRs), the venue offers a modest but consistent offensive boost. The edge isn't large enough to override pitcher matchup or weather signals on its own, but it's consistently in the bettor's favor for hitter-friendly prop lines. 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 Fenway Park translates into actionable edges. Home run props at Fenway Park should be evaluated mostly on pitcher matchup and batter form rather than park factor. The venue is neutral enough that other variables dominate. Because Fenway Park 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.
