Baseball betting: moneyline, run line and totals

How MLB odds work, why starting pitchers move prices so much, and how our runs model is built.

Updated October 4, 2026

Baseball betting rewards patience. It is a long season of short margins: even the best MLB teams lose around 40 % of their games, and the worst still win plenty. That narrow spread of outcomes is why the moneyline dominates baseball, and why one variable — the starting pitcher — can swing a price more than in any other team sport.

Baseball betting markets

Moneyline

Pick the winner, extra innings included. Because talent gaps are narrow, prices are rarely shorter than 1.40 or longer than 3.20 in MLB. A typical game might be 1.75 against 2.15.

Run line

Baseball's handicap is fixed at ±1.5 runs. A favourite at −1.5 needs to win by two or more, which lengthens its price considerably — often from around 1.60 on the moneyline to 2.30 or more. The underdog at +1.5 wins if it wins or loses by exactly one run, and one-run games are very common in baseball.

Totals

Combined runs scored. MLB totals usually sit between 7 and 10. Ballpark, weather and both starting pitchers shape the line: a hitter-friendly park on a warm day with the wind blowing out is a very different game from a cold night facing two aces.

How our baseball model works

Baseball sits in the goals-model family alongside football and hockey. Each team has an offensive and a pitching-and-defence strength drawn from past results, and these give an expected number of runs for each side. But runs don't arrive one at a time like football goals: a single inning can produce four or five, and big innings happen more often than a Poisson curve would predict. So for baseball we use a wider distribution, the negative binomial, which allows for those clusters.

From the resulting grid of possible scores we derive the moneyline, the run line and the totals, so the three markets stay consistent with each other. See how we price odds for the full method.

Season and competitions

MLB teams play a 162-game schedule that starts in spring and only lets up as autumn arrives, with games nearly every day, followed by a postseason in October: wild-card series, division series, league championship series and the World Series. The daily schedule makes baseball a volume sport for bettors, and the heavy fixture load means rest days and bullpen fatigue genuinely matter. Japan's NPB and Korea's KBO run on a similar spring-to-autumn calendar.

Baseball betting tips

• Check the probable pitchers. A late change of starter can change everything; markets close 1 minute before first pitch, so confirm before you bet.
• Bullpens count too. Starters rarely go deep nowadays; a tired bullpen after a long series can lose a game in the seventh.
• Weather and park. Wind direction and temperature move totals more than most people expect.
• Don't chase short prices. Even a 1.50 favourite loses one game in three. Flat stakes, as in our bankroll guide, suit baseball's long season.
