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
24.8%

Share of the 125 decided meetings settled by exactly one run.

Won by 2 or more
75.2%

A 2+ run margin crosses 1.5, but this is not a historical line result. Average gap: 3.6.

Average total
9.6runs

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

Home side wins
40.8%

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.

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.

Kansas City Royals

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.
