Why Handedness Matters for Home Run Props

Why batter hand, pitcher hand, park dimensions, and pull-side power matter when reviewing MLB home run data.

Updated 2026-05-09

What Handedness Means

Handedness refers to which side of the plate a hitter swings from and which arm a pitcher throws with. Lefty/righty matchups are a foundational layer of baseball analysis.

Batter Hand vs Pitcher Hand

Hitters often have different power profiles vs same-handed and opposite-handed pitching. The platoon advantage is real and shows up in HR data.

Platoon Context

A right-handed hitter facing a lefty often sees a different pitch mix and gets more pitches in his power zones.

Park Dimensions by Side of the Field

Many parks favor one side. Read more on ballparks.

Wind Direction and Pull-Side Power

Wind blowing out to right helps lefty pull power; wind out to left helps righty pull power. Read more on wind.

Pitch Type and Handedness

Pitch mix changes with handedness. Lefty hitters see more sliders away from righties; righty hitters see more changeups from lefties. Read more on pitch type.

Every HR on the tracker shows batter hand and pitcher hand. Player pages break down HRs by pitcher hand.
