Miami vs Philadelphia: First Inning Run

Prediction markets frequently incorporate breaking news and sharp analysis faster than traditional books adjust, making them a useful signal for comparing against published sportsbook lines. Comparing the two can reveal where informed traders see value relative to conventional oddsmakers.
