SEAGER+ and decision components
SEAGER+ is the promoted plate-discipline index; component rows marked rebadged research are visible diagnostic context, not standalone promoted metrics.
xwOBA snapshot line
Live snapshot series; true 50/100 PA windows require PA-level logs
Swing path and decision map
Mike Yastrzemski's tools (93) outpace production (86) by 7 points. Primary finding: expanding the zone too aggressively — generating weak contact and whiffs on pitcher's pitches. Also flagged: Contact-Discipline Mismatch.
Shorten swing against breaking balls while maintaining bat speed on fastballs
Protected takes / Chase riskField-coordinate spray profile
110 Statcast batted-ball coordinates from the pitch-event feed (2026). Direction profile remains as the v1 context layer when coordinate density is limited.
