How this is calculated
Stats reflect only Aaron Boone's tenure as Yankees manager — events from before the start date or after the end date are excluded. Lineup cost is the difference between an optimized batting order and the one actually used, summed across regular-season games. Bunt and intentional-walk costs come from per-decision run-expectancy deltas. Pitching cost is the sum of pull-timing and reliever-selection runs lost. Costs are shown as a season total and a per-game rate (R/G); rankings compare this tenure's per-game rate against the league-wide distribution of current and recent manager tenures. RunsLeft does not assign letter grades — the costs and rankings are descriptive analytics.
