Per-pitch-type usage and stuff metrics. Season aggregates beside the last 5 outings — divergence between the two columns is the leading indicator that something has changed (velocity loss, command drift, batters adjusting). xwOBA measures contact quality (lower is better for the pitcher); whiff% and chase% are the swing-and-miss signals.
