How to read thisLocations show the mean crossing point at home plate. Halos show one standard deviation, so larger halos mean a less concentrated location pattern. Period arsenals combine pitches across every team. All statistics, ranks, team attribution, and pitch qualification are recomputed within the selected window. The team label comes from the pitcher’s latest tracked Statcast pitch in that window.
