What the MLB Run Line Actually Means for Your Bet
In baseball, the standard spread is almost always set at 1.5 runs. A favorite listed at -1.5 needs to win by at least two runs for your bet to cash. An underdog at +1.5 covers even if they lose by one. That fixed gap changes the odds significantly compared to the moneyline — a heavy favorite that's -200 on the moneyline might
be priced closer to -120 on the run line because they now need a bigger margin. Pitching matchups, bullpen depth, and ballpark factors all shift how that 1.5-run spread plays out across a nine-inning game. We display both lines side by side so you can compare value at a glance.
