Once the game ends, a full pitching and bullpen breakdown appears here: starter lines, the relief sequence and each arm's role, pitch counts, and where the game turned.

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.
