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
23.1%
Share of the 432 decided meetings settled by exactly one run.
Won by 2 or more
76.9%
A 2+ run margin crosses 1.5, but this is not a historical line result. Average gap: 3.8.
Average total
9.9runs
Final-score average without accounting for park, bullpen or weather.
Home side wins
47%
Share of decided meetings won by the listed home team.
Totals ladder
Where the combined score landed against the half-run lines a book normally posts. Half runs cannot push, so every meeting falls on one side.
| Line | Over | Under | Over rate |
|---|---|---|---|
| 7.5 | 283 | 149 | 65.5% |
| 8.5 | 247 | 185 | 57.2% |

Fair price from the base rate

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.
