Covering the Spread

Definition:

In sports betting, to cover the spread means a team performs well enough relative to the point spread for bets on that side to win. Favorites must win by more than the spread, while underdogs must lose by fewer points than the spread (or win outright).

They serve two main purposes:

1. Clarify whether a bet on the spread is successful.

2. Provide a clear measure beyond simply winning or losing the game.

Real-World Example

NFL Game: Baltimore Ravens –6.5 vs. Tennessee Titans

• If the Ravens win 28–20, they cover the spread (win by 8).

• If the Ravens win 21–17, they do not cover (win by only 4).

• If the Titans lose 24–20, they cover the spread as underdogs.
