Understanding MLB Betting Odds
Major League Baseball's 162-game regular season makes it one of the most volume-driven sports for betting. The long season means variance plays out heavily — even the best teams lose roughly 40% of their games, and the worst teams still win around 35-40%.

MLB Run Lines
The standard MLB run line is -1.5/+1.5, similar to the NHL puck line. The favorite must win by 2+ runs to cover -1.5. Because most MLB games are decided by 1-2 runs, the run line on underdogs (+1.5) cashes at a high rate but at short prices.
The moneyline is the primary betting market for MLB. Starting pitcher matchups are the single biggest factor in MLB odds — aces can move a line 30-50 cents compared to a fifth starter. Always check the probable starters before placing an MLB bet.
MLB Betting FAQ
What is the run line in MLB betting?
The run line is typically set at -1.5/+1.5. The favorite must win by 2 or more runs to cover the -1.5 run line. The underdog +1.5 wins if they lose by exactly 1 run or win outright.
How much does the starting pitcher affect MLB odds?
Starting pitchers are the primary driver of MLB moneylines. A top-tier starter can make a team a -200 favorite, while the same team with a replacement-level starter might be +120.
