The week’s largest MLB leader flip
Milwaukee led early, but Pittsburgh finished with the pre-game edge after a 16.09-point leader swing.
What changed
Reading the trace.
Across all 48 scheduled MLB games in the week, Brewers–Pirates produced the largest observed leader flip. Milwaukee held 53.6% at the first qualified observation. Pittsburgh held 54.4% at the final pre-game check.
Pittsburgh completed its Saturday doubleheader sweep 66 minutes before the first captured Pirates lead. MLB later reported that Milwaukee manager Pat Murphy announced Jacob Misiorowski would be scratched with arm fatigue and Robert Gasser would start instead.
The sequence is notable, but it is not proof of cause. The report supplies a postgame announcement window rather than a minute-level timestamp, and the captured trace cannot establish that the pitching change was the market’s only driver.

Aggregate prices were normalized into market-implied win probabilities. The trace begins with the first observation meeting the coverage threshold and ends at the final pre-game check; external events are timing context, not causal claims.
