How Fenway Park plays
Against right-handed hitters Fenway Park is pitcher friendly for home runs, with a home run factor of 85 in 2026. Against left-handed hitters it is pitcher friendly, at 92. At 21 feet, elevation is not a meaningful factor here.
As an open air ballpark, wind and temperature move the numbers above on any given night. The park factor is the long run baseline, not the forecast for today.
Reading these numbers
Each column is an index where 100 is the league average for that outcome. The home run column is the one that moves DFS and betting decisions most, because home runs are the highest variance scoring event and the one most sensitive to stadium shape. The hard hit column is useful as a check: if home runs are elevated but hard hit contact is not, the park is converting ordinary contact into home runs through its dimensions rather than through better hitting.
Read the row that matches which side of the plate the hitter stands on. A single blended number hides the handedness split, which at an asymmetric park is usually the part that matters.
