Sportsbook lines next to every game
Moneyline, run line and total from 4 to 13 books per game from 2015 to 2023, joined to the result, our ratings and the box score.
Baseball odds history is scattered, rarely names the book, and does not come with the game attached.
A backtest needs the price you could have taken and what happened, in one row.
What to build
Closing-line backtests
Pull a day's lines by book with whether the favourite won and the total went over, and test a rule against the price.
Ratings against the market
Compare our Elo and Pythagorean records with each game's implied probability.
Totals and run environments
Runs per game and team OPS for and against, next to each game's total.
What it will not do
- Since 2024 most games have one book in the source.
- No player props.
- No live in-game lines.
