Season percentile report
The headline weighs outcome stats (xwOBA, barrels); each bar averages its full strip group below. 100 = best in MLB.
percentile
Preseason / current pace / Bayesian update
Rolling bands shrink current-season signal toward the preseason prior until the sample earns more weight.
| xwOBA preseason | 0.288 |
| xwOBA current pace | 0.353 |
| xwOBA rolling p50 | 0.332 |
| Observed weight | 67% |
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
Sal Stewart's tools (52) outpace production (70) by -18 points. Primary finding: excellent plate discipline but too passive on hittable pitches — letting strikes go by.
Field-coordinate spray profile
211 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. The full swing, with the recommended path overlaid, lives in the 3D Swing Simulator.
Aggregate zone heatmap
Aggregate zone metrics from seasonal Statcast leaderboards.
