What Makes the MLB Run Line Different
In most American sports, the spread floats based on matchup strength. MLB is different — the run line is fixed at 1.5 runs for every game, and the sportsbook adjusts payout odds instead of moving the number. When you back a favorite at -1.5, they need to win by two runs or more for your selection to cash. Take the underdog at
+1.5, and they cover even if they drop the game by one run. From Atlantic City to wherever you catch the slate, our MLB game cards show the run line alongside the moneyline and run total so you can weigh the tradeoff in one view. Access depends on your state and local law.
