Park-factor read
Fenway Park is more matchup-driven than reputation-driven. Fenway Park is the Boston Red Sox home park in Boston, MA. For betting, the useful question is not whether the park is "good for hitters." It is which markets the venue changes most: home runs, run scoring, hits, or weather-sensitive totals.
The shortest corner is 302 feet and the deepest listed alley is 390 feet. That shape helps explain why fly-ball hitters can matter here, especially when the weather is also helping carry.
A 1.15 home run factor gives power bats a real venue bump, but it still needs the right matchup and weather. The 1.08 run factor is meaningfully above average, so strong lineups and shaky bullpens get a little louder.
Fenway Park is open-air, so wind, temperature, and humidity can move the run environment. Always check the daily weather before treating the static factor as final.

History and naming
Fenway Park opened in 1912 and serves as the home venue for the Boston Red Sox. That matters for searchers and bettors because venue names, naming-rights language, and team shorthand often get mixed together in MLB research. This profile uses the current venue identity, then connects it to the team, city, roof type, dimensions, and betting factors that actually affect the game. At 37,755 listed capacity with grass playing surface, Fenway Park is one of MLB's century-old venue anchors. The page cites Wikidata, Wikipedia, Official venue/team site for basic identity facts, but the park-factor interpretation is original analysis from thecapper.io.
Use Fenway Park, Boston Red Sox, and Boston, MA together when comparing park-factor research. Fans may search by team, city, nickname, sponsor name, or older venue wording, but the betting question is the same: which run environment is attached to today's home team? This page keeps the current official venue name tied to the Boston Red Sox profile so related pages, game previews, tools, and model explanations can point to one canonical ballpark URL.
Seasonal environment
Fenway Park is open-air, so the same dimensions can play differently by month. Cooler April and May nights can mute carry, summer heat can help the ball travel, and late-season weather can introduce sharper wind and temperature swings. For totals, home run props, hits, and NRFI/YRFI, treat the static park factor as the baseline and game-day weather as the adjustment.
Early-season games can be the most misleading because the listed park factor is season-neutral while temperature, wind, and lineup timing are not. Be careful with overs, home run props, and small-sample venue trends when the weather is cold.
Warmer air generally helps carry and can make hitter-friendly parks more dangerous. In pitcher-friendly parks, summer weather can narrow the gap between the static factor and the live betting environment.
September baseball can bring cooler nights, different shadows, bullpen fatigue, and lineup churn. That makes the park profile useful, but it should be paired with current team context and confirmed lineups.
Venue trends
A static park factor tells you the baseline. Recent results show how the park has actually played this season: totals, team scoring, first-inning scoring, and tracked pitcher strikeout props.
Use the windows as a sanity check, not a pick generator. If the last 5 and last 10 are running hot but the season line is neutral, ask whether weather, opponent quality, or bullpen chaos created the spike. If every window points the same way, the venue signal is more interesting.

Quirks explained
Ballpark quirks are only useful when they are translated into baseball outcomes. The notes below explain what each feature can change: pull-side power, doubles and triples, hit probability, totals, or weather sensitivity.
The Green Monster makes Fenway different from a normal short left field. High fly balls that would be outs elsewhere can become wall doubles, while some would-be homers stay in play. That matters most for doubles, total bases, and right-handed pull contact.
Pesky's Pole creates a very specific left-handed pull-power target. It can help a hitter who lifts the ball down the right-field line, but it should not be treated as a blanket boost for every batter or every fly ball.
Deep alleys and unusual outfield angles increase extra-base volatility. They can suppress some cheap home runs while creating more room for doubles and triples when line drives split the gaps.
