What the MLB Run Line Actually Means
In MLB, the standard point spread is set at 1.5 runs. Back the favorite at -1.5 and they need to win by two or more; take the underdog at +1.5 and they just need to keep it within one run or win outright. Unlike NFL spreads that shift across a wide range, baseball's fixed 1.5 margin means the price — the juice
— moves instead of the number. A -1.5 favorite might cost -180 one day and -160 the next based on the starting pitcher matchup. Checking those price shifts before you lock a wager is exactly where our odds display earns its keep. Same-game parlays let you stack the run line with a first-five-innings total or a strikeout prop on the same ticket.
