A spray chart turns a season of balls in play into one picture of where a hitter puts the ball.
What a spray chart shows
Each mark is a ball put in play, placed where it landed on the field, usually colored by hit type: ground ball, line drive, fly ball, or by result such as single, out or extra-base hit.
Read direction first
Is the hitter pulling everything, going the other way, or spraying all fields? A tight cluster to the pull side is the clearest signal on the chart.
Then read hit type
A hitter who pulls ground balls calls for a different shift than one who lifts fly balls to the gap. Filter by hit type to see it.
Turn it into a plan
Move fielders toward the clusters, and pair the chart with pitch location so you know which pitches produce the weak contact you want. In ScoutBall AI's Pitch Chart you can filter the spray chart by outcome, player, pitch type or inning.
Small samples mislead. Look for patterns across several games before making a big shift.
