Sources & method

The chart uses MLB’s win-probability model after each batter. Dashed marks show run support from teammates: 1 run in the 2nd, 1 run in the 3rd, 2 runs in the 5th. Those changes are not credited to the pitcher.

This is the whole appearance for one pitcher on the day’s board, built when you selected him. The game is final. Read 6:27 AM ET. Win probability, plays and pitch tracking: MLB win-probability feed; lines and decisions: the game’s MLB game data. The notes are written from those measurements, not by a person. They describe the pitches, not why a batter swung or took.
