If a team is -1.5, they are expected to win by two or more. If a team is +1.5, they are expected to lose by one or win outright. The spread is basically the number of runs a team is expected to win or lose by. The line is typically 1.5 runs but can be anything, especially with live betting. This line (or “spread,” as it is called in other sports) evens out or flips the odds. Since games between uneven teams might have odds at extremes, most sportsbooks also offer a run line for bettors to consider.
