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.

Small sample: 35 decided meetings, under the 50 we treat as the floor for a stable rate. Read the figures below as description, not a forecast. Interleague pairs meet in short bursts, so a single series can move any percentage here by several points.

One-run games
45.7%

Share of the 35 decided meetings settled by exactly one run.

Won by 2 or more
54.3%

A 2+ run margin crosses 1.5, but this is not a historical line result. Average gap: 2.9.

Average total
9.1runs

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

Home side wins

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 all-time record and the History Lab use Retrosheet game logs through 2025, with inning lines, team totals, attendance, duration and ballpark fields when available. Final games after 2025 come from the current feed, and every section built on that feed alone is labeled as starting 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.
