Diamondbacks Run Line vs. Cubs: Where the Market Disagreed Tonight

The value here isn't a bold prediction that the Diamondbacks blow out the Cubs. It's in the pricing. When we compared the run line across the market, the books disagreed with each other, and the best available number on Arizona covering the larger margin came in better than the no-vig fair line we calculated. That's a genuine, and fairly rare, edge, one that exists in the number itself rather than in any certainty about the outcome.

To be clear about what this is and isn't: covering a multi-run spread in baseball is volatile, and one bad inning can flip it. This isn't a claim that Arizona is a sure thing over Chicago tonight. It's a reminder that shopping for the best price on the same bet changes your long-run expectation, and on this game the difference was worth noticing. Varsia flagged it; whether it fits your read on the matchup is the call you make.
