How do MLB odds work?

The most popular odds for Major League Baseball (MLB) aren’t much different to those for other sports. Traditional baseball betting markets include the moneyline, total or over/under, run line, prop bet, and futures. Numerous sportsbooks offer odds for every game of the MLB season, which are dependent on factors such as trends and injuries.

Some MLB odds, such as futures, are typically set in preseason, meaning you can bet on things such as which team will win the World Series or which player will be crowned MVP before the campaign has even started. Live in-game odds are also available if you want to place bets during a game.

To help you with all of this, BET.CA has the latest MLB odds from a range of reviewed and approved sportsbooks, so it’s easy to ensure that your baseball bets get the best possible value.

Popular MLB bets

There are several types of MLB bets that you can make, including the moneyline, total or over/under, run line, prop bets, and futures. Read on to learn more about each of these in more detail.

MLB moneyline odds

Betting on MLB moneyline odds is arguably the most straightforward baseball bet that bettors place. When placing an MLB moneyline bet, you are simply predicting which team will win.

Here is an example of moneyline odds for a MLB game:



Toronto Blue Jays


Baltimore Orioles


If you were to place an $100 moneyline wager on the Blue Jays and they won the game, you would get a payout of $166.67 (your $100 bet plus $66.67 profit). If you were to place the same bet on the Orioles and they won, you would receive a $250 payout (your $100 bet plus $150 profit). Naturally, a successful bet on the underdog would yield a more profitable return.

Another thing to note is that MLB betting lines are sometimes not adjusted to factor in certain news, at least not immediately. For example, if the Blue Jays starting pitcher was a late scratch because of an injury, they would be forced to use an emergency spot starter. The odds may not adjust to this news in time for the first pitch, so a timely bet on the Orioles in this scenario could pay dividends. If this happens, you may need to place your wager again, as some sportsbooks void your bet if the starting pitcher changes.

MLB run line odds

MLB run line odds is essentially a two-in-one bet. Not only are you betting on one team to win or lose, but you’re also betting on them to do so by a run total that falls within a certain range.

MLB run line betting comes down to betting on one of two outcomes. You either bet on the favourite to win by more than the run line or you will bet on the underdog to lose by less than the run line (or to win). MLB run line odds are usually set at +/-1.5 depending on whether a team is the favourite or underdog.

Here is an example of run line odds for a MLB game:

Team and run line


Atlanta Braves, -1.5


Houston Astros, +1.5


For example, if you placed a $100 run line bet on the Braves at -1.5 runs with +110 odds and they won by two or more runs, your bet would win and you would get a payout of $210 (your $100 bet plus $110 profit). If you were to bet on the Astros at +1.5 runs with -110 odds and they lost by one run, or won, your bet would win and you would get a payout of $191 (your $100 bet plus $91 profit).

MLB total or over/under odds

MLB totals odds (also often referred to as over/under odds) relate to the final score of a baseball game. Every MLB game is given a predictive total for the number of combined runs both teams will score by game’s end. For example, if a game’s over/under total is set at 6.5 runs, betting the under would involve wagering on six or fewer total runs being scored, while betting the over would mean wagering on seven runs or more being scored.

MLB over/under odds are often set to .5, e.g. 5.5, as scoring half a run is impossible, meaning a definitive over/under amount will be guaranteed by game’s end. If an MLB over/under total is set as a whole number and that number of runs are scored during the game, the bettor will receive a refund on their bet known as a push.

Here is an example of total or over/under odds for a MLB game:



Over 6.5


Under 6.5


The odds for betting the over are -150, whereas the odds for betting the under are +150. If you were to place an $100 bet on the over and won, you would win $167 (your $100 bet plus $67 profit). If you placed that same bet on the under and won, you would win $250 (your $100 bet plus $150 profit).

MLB parlay odds

An MLB parlay bet involves wagering a single amount on multiple baseball bets combined into one. The payouts for parlay bets are often much higher than if the selections were placed as individual bets, although the catch is that every selection on the bet must come in for it to win. There are many different kinds of baseball bet you can combine for a parlay. For example, you could create a parlay combining a moneyline bet on one game, a run line bet on another, and a total or over/under bet from a third. Some sportsbooks offer same-game parlays, but these can be difficult to find.

Here is an example of an MLB parlay bet on three different games:



LA Dodgers to beat San Francisco Giants


Boston Red Sox, -1.5


Over 6.5 in Tampa Bay Rays @ Chicago White Six


Three-way parlay odds


If all three selections came in, a $100 wager would net a total payout of $758 ($658 profit), which is considerably more than if three selections won as individual $100 bets. However, if only two of the three selections won, the bet would lose.

Betting on MLB futures

MLB futures betting centers around wagering on events that cannot be settled until a future date and are often decided at the end of the season. For example, popular MLB futures markets include which team will win the World Series and which player will win the MVP and Cy Young awards.

Naturally, these are the hardest outcomes to predict, meaning the odds are often lucrative for every option. For example, the odds for someone like Mike Trout to win MVP could be as high as +500, even though he has done so multiple times before.

There are several different types of MLB futures markets available, and sportsbooks often offer odds for them both before and during the season. As a result, futures odds can fluctuate throughout the season depending on the performances of certain teams and players.

MLB prop bets

MLB prop bets refer to wagering on in-game events. Prop betting can be applied to a team, an individual player, or any other kind of in-game event. Bets of this nature initially began in the 1980s as a means of promoting sports betting to casual fans watching the Super Bowl, and has grown astronomically since.

Popular MLB prop bets include predicting the first home run hitter, guessing the over/under of a pitcher’s strikeout total, and whether or not a run will be scored in a specific inning. MLB prop bets are often the most common way to get involved with live in-game betting, which only further increases the volatility thanks to the constantly fluctuating odds throughout a game.

For example, if a team is being shut out through six innings, the odds of them scoring in the seventh are low and even a small prop bet on them doing so could yield a big payout if it happens.
