Preseason / current pace / Bayesian update
Rolling bands shrink current-season signal toward the preseason prior until the sample earns more weight.

Actual percentile with projection tick
100th = best in MLB.
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
Pete Alonso's tools (88) outpace production (82) by 7 points. Primary finding: excessive fly-ball angle — producing popups instead of line drives.
Field-coordinate spray profile
178 Statcast batted-ball coordinates from the pitch-event feed (2026). Direction profile remains as the v1 context layer when coordinate density is limited.
Swing path, attack angle, bat speed
Aggregate Savant bat-tracking metrics; not per-swing motion capture.
Aggregate zone heatmap
Aggregate zone metrics from seasonal Statcast leaderboards.
