How RunsLeft analyzes games
Standard content on this page comes from the MLB Stats API. The pitching analysis describes how the game was pitched — the starter's line, the bullpen sequence and each arm's role (opener, bulk, setup, closer), pitch counts as a fatigue signal, and the leverage context where the game turned. Reliever roles are inferred from how the manager used each arm up to that date. It describes structure and constraints; it does not grade the manager.
