O27's single 27-out half shows little through-the-order penalty — starters don't fade the way a 9-inning workload makes them.
Win probability is split by batting half (using the persisted bat-first flag), so it respects O27's two-sequential-halves structure. Fielding OAA uses the engine's exact fielder on outs (44.3% of chances) and trajectory-zone attribution for balls that fell in; the expected out-rate is conditioned on the fielder's zone, so the metric is position-neutral and home runs are excluded. FRV regresses OAA toward league-average by sample reliability and is the defensive run value that feeds WAR. Pitch-arsenal run value covers balls in play (contact quality), not whiffs.
