What is a Spray Chart? Definition and Examples
A spray chart is a bird's-eye diagram of a baseball field on which every batted ball a hitter puts into play is plotted by landing location and outcome, making pull tendencies, opposite-field ability, and gap-hitting profiles immediately visible.
What Is a Spray Chart?
A spray chart is a bird's-eye overhead diagram of a baseball field on which every batted ball a hitter puts into play is plotted as a dot, line, or shaded zone. Each plotted ball indicates landing location, outcome (hit, out, or error), and typically ball type (line drive, fly ball, ground ball). Spray charts convert thousands of individual at-bats into a single visual — revealing whether a hitter pulls everything to one side, uses the whole field, or concentrates damage in specific zones like the left-center gap or right-field corner.
How Spray Charts Are Generated
Statcast tracks every batted ball using Doppler radar and high-frame-rate cameras installed in all 30 MLB parks. The system records three values relevant to spray charts:
Spray angle: The horizontal angle of the ball off the bat, measured in degrees relative to straight center field. For a right-handed batter, negative angles indicate the pull side (left field); positive angles indicate the opposite field (right field). For a left-handed batter, the pull side flips to right field.
Distance: The projected or actual distance from home plate.
Landing coordinates: The precise X/Y location where the ball first contacts the surface or departs the park.
Baseball Savant's public spray-chart tool plots these values for any player or date range. Charts can be filtered by handedness of pitcher faced, pitch type, count, or season, allowing fine-grained analysis of situational hitting tendencies.
Worked Example: Aaron Judge vs. Tony Gwynn
Aaron Judge's spray chart is a right-handed power hitter's archetype. His batted-ball distribution clusters heavily toward the pull side — roughly 45–47% of his balls in play travel to left field or left-center. His hardest contact, measured by exit velocity, concentrates in the left-center power alley and over the left-field wall. His opposite-field output exists mainly as soft ground balls and looping singles — defensive contact, not damage.
Tony Gwynn's career spray chart, reconstructed from pre-Statcast video and scouting accounts, presented the opposite profile. Gwynn deliberately let pitches travel deep into the hitting zone before contact, directing the ball toward right field. His philosophy: attack the outer half to right field, deny pitchers an easy inside-corner strategy. He produced consistent spray charts tilted toward right and right-center even when pitchers worked him inside — an ability reflected in his record eight batting titles.
Why Spray Charts Matter
Defensive positioning: Before MLB banned the shift in 2023, spray charts were the primary input for overloading the pull side with three infielders. Today teams still use spray-chart data within the legal two-infielder-per-side arc to shade positioning based on individual pull tendencies. The ban changed formation, not the analytical foundation.
Pitching strategy: Opposing pitchers review spray charts before starts to identify attack zones. A heavily pull-side chart tells a right-handed pitcher to work glove-side away, removing the hitter's natural swing path. A balanced distribution signals a disciplined contact hitter who cannot be neutralized with one approach.
Fantasy and BABIP: Batted-ball direction affects BABIP sustainability. Hitters who pull hard ground balls produce higher BABIP floors because pulled grounders reach the gap before fielders can rotate. A spray chart that shows hard-hit pull-side ground balls predicts above-average BABIP without luck involved. Spray data surfaces this before BABIP actually rises.
In Legends Deck, each player card carries a spray-angle distribution sourced from their real Statcast data. The simulation engine uses this distribution to place batted balls on the field during game play — pull-heavy power hitters generate more left-field home runs; balanced contact hitters produce wider gap-to-gap hit distributions that play differently against various defensive configurations.
Limitations and Misconceptions
Spray charts show where the ball went, not why. A hitter who pulls everything might be elite at recognizing inside pitches and rotating early — or might be getting jammed on pitches away and yanking weak grounders. Spray direction requires exit velocity and launch angle context to separate quality pull contact from defensive weak-contact pulls.
Sample size matters significantly. A 40 plate-appearance spray chart is noise. Reliable pull-tendency signals emerge around 300–400 PA; full-season charts (550+ PA) are stable enough for defensive positioning decisions.
Opposite-field hits are not all equal. A 105 mph line drive to right-center from a left-handed batter is an entirely different event from a 78 mph flare to the same location. Both plot identically on a standard spray chart. Exit velocity overlays — available on Baseball Savant — are necessary to distinguish true opposite-field power from defensive pokes.
