Lock Meaning – A Bet That’s Perceived as a Sure Thing That Can’t Miss

A lock is a sports betting term for a “sure bet.” In other words, when bettors consider something a lock, they think it will definitely be a winner. It can also be used in a negative context, when a team or player is a lock on a losing side.

For example, you can say that “Liverpool is a lock for the Champions League tonight” or that “The Miami Heat are a lock to lose the Eastern Conference.”

Keep in mind that there are rarely any sure bets in sports, so people who often claim they have a lock on a bet are likely scammers.
