How Pitch Type Affects Home Runs

How pitch type can help explain MLB home runs, including fastballs, sliders, sinkers, breaking balls, and off-speed pitches.

Why Pitch Type Matters

Different hitters punish different pitches. Some hitters live on fastballs; others crush breaking balls. Pitch type is part of the HR story.

Fastballs

Four-seamers up in the zone are the most common HR pitch. Hitters with big lift and quick bats live here.

Sinkers

Sinkers down get ground balls when located, but flat sinkers get crushed.

Sliders

Hanging sliders are a classic HR pitch. Sweepers that don't move are punished by power hitters.

Curveballs

Hung curveballs are a common HR mistake. Sharp curves are usually safe.

Changeups and Splitters

Off-speed left in the zone gets crushed. Out of the zone, both pitches get whiffs.

Pitch Velocity

Velocity matters. A 92 mph fastball is more hittable than 97. A 78 mph slider is more hittable than 86.

Batter Swing Profile

Some hitters are dead-zone hunters; others sit on a specific pitch. The swing profile interacts with pitch mix.
