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: 41 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
26.8%

Share of the 41 decided meetings settled by exactly one run.

Won by 2 or more
73.2%

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

Average total
10.1runs

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

Home side wins
51.2%

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.
