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.

Team scoring environment
This connects the player page back to the team scoring profile, which matters when a player is being evaluated inside a moneyline or total bet.
Recent runs allowed with average margin -2.0.
Average actual total 9.6 vs tracked 10.0.
Use this section together with the game log and trend chart on the page: a hot bat on a team scoring well is different from a hot bat inside a low-scoring team context, and the same idea applies to pitchers on teams playing high-total games.
