Betting Context

Betting context since 2002

How this pairing has settled: run margins, totals and break-even prices derived from its historical record. These are final-score frequencies, not results against a closing line. We do not hold historical sportsbook prices for these games.

One-run games
27.5%

Share of the 109 decided meetings settled by exactly one run.

Won by 2 or more
72.5%

A 2+ run margin crosses 1.5, but this is not a historical line result. Average gap: 3.8.

Average total
9.8runs

Final-score average without accounting for park, bullpen or weather.

Home side wins
51.4%

Share of decided meetings won by the listed home team.

Fair price from the base rate

The decimal price that corresponds exactly to each club's win share in this archive. It describes the record and does not estimate the next game.

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.
