29.5%
Share of the 95 decided meetings settled by exactly one run.
Won by 2 or more

A base rate is not a forecast. Starting pitchers, lineups, injuries and venue all matter more to a single game than a multi-season head-to-head record.

Methodology & Data Sources
Current MLB game logs come from the balldontlie API and cover the 2002 season onward. Scores and schedule anomalies are checked against the official MLB Stats API. Spring training is excluded, while results from earlier franchise identities are merged into the current club.
The History Lab uses Retrosheet game logs through 2025, with inning lines, team totals, attendance, duration and ballpark fields when available. Its source window is labeled separately from the refreshed current feed that starts in 2002.
The betting context summarizes completed final scores only. It contains no sportsbook closing lines and summarizes only completed games. Report a possible error through our contact page with the matchup and game date.
