Rules
The 60-second explainer.
What's a splat?
Every fair ball hit into play paints a mark where it lands, normalized onto one canonical ballpark so every game and every player is compared on the same field. The size of the mark scales with contact quality — measured by xwOBA, not just exit velocity, so a screaming line drive paints bigger than a routine popup hit just as hard.
The shape of the mark encodes how the ball got there: grounders leave a streak along their path to the fielder, line drives stretch into an ellipse pointed away from home plate, fly balls and popups bloom into round discs, and home runs land out past the wall, in the stands.
Two canvases
Game canvas — newest paint wins
One game, two painters — home team vs. away team. Every ball paints in strict chronological order, and the newest paint always wins, no matter how strong the contact. It's a live map of who's controlling the field right now.
Season canvas — hardest-hit paint wins
One full season, player vs. player. A cell only changes hands when a harder-hit ball lands there — ties leave the incumbent in place. The map accumulates all year and resets fresh on the next Opening Day.
Foul balls
Nothing. Foul territory never paints — only fair balls in play count.
Every fair ball paints the diamond where it lands — hardest-hit paint owns the season map, newest paint wins each game. Who owns the diamond?
