What happens in St. Louis vs San Francisco first inning?

Sportsbooks set lines based on their own models and often incorporate a profit margin, while this market relies on traders directly expressing their beliefs about the likelihood of a first inning run.

It's important to note that these are distinct sources of information, each with its own strengths and biases, and comparing them can be a valuable part of your analysis.
