Strike Zone
The strike zone is the three-dimensional region over home plate, between the batter's knees and the midpoint of the torso, where a pitch must pass to be called a strike.
Officially the strike zone extends from the hollow below the kneecap to the midpoint between the top of the pants and the shoulders, and from the inner edges of home plate. In practice it varies by umpire and context. Pitchers who "work the zone" — attacking edges rather than the fat middle — limit hard contact and earn more called strikes. Hitters who understand the zone swing at strikes and take balls, improving on-base percentage and pitch count pressure. Zone awareness is foundational to both crafts.
Example
He painted the black on the low-outside corner — a pitch technically in the strike zone but nearly impossible to drive for power.
Why it matters
Understanding where your pitch finishes relative to the strike zone shapes pitch selection and sequencing. SwingVantage maps location relative to the zone on every filmed rep.

- Pitch SequencingPitch sequencing is the art of ordering pitches to exploit a hitter's tendencies and set up future offerings — making each pitch more effective because of what came before.
- Plate DisciplinePlate discipline is the ability to distinguish balls from strikes and to swing only at pitches where the hitter can do damage — the foundational mental skill of hitting.
- Zone HittingZone hitting is the approach of only swinging at pitches in the specific area of the strike zone where the hitter is most dangerous — avoiding the edges where their swing produces weak contact.
- Walk RateWalk rate (BB%) is the percentage of a hitter's plate appearances that end in a walk — an indicator of plate discipline, pitch recognition, and the ability to take advantage of a pitcher's wildness.
- Strikeout RateStrikeout rate (K%) is the percentage of plate appearances that end in a strikeout — elevated K% reduces a hitter's value by eliminating batted-ball outcomes entirely.
