Opening Line
The initial odds or point spread set by the bookmaker for a fight or game. This is the line at which betting begins, before any significant action or news causes movement. It represents the bookmaker’s early projection of fair odds (with vig).
The **opening line** for Crawford vs. Canelo might be Canelo -150 (Crawford +130). If a lot of money comes in on Crawford, the line could move off the opener. Bettors who agree with the bookmaker’s initial odds often try to bet the opening line before it moves.
