Ballpark Profile
A one-of-a-kind shape: the 37-foot Green Monster guards an extremely shallow left (310 ft), turning fly balls into doubles, while a short Pesky Pole (302 ft) aids left-handed pull. Open-air near the harbor, so wind is a meaningful daily swing.

Overall factors are Baseball Savant 3-year-rolling Statcast park factors vs MLB average. Fence distances and wall heights (the blue marks up top) are Savant's official 2025 dimensions. Per-zone HR shading is modeled from those distances + heights + the handedness splits, normalized to the overall factor (a model, not measured per-zone). New venues without full data fall back to internal estimates.
