MLB Betting: Types of Bet You Can Place

With your sign up process and initial deposit done, you are good to go with regards starting your MLB betting activity.

You’ll need to be aware of the various kinds of bets that can be placed, so we’ve outlined the main types of MLB bet for you here.

Moneyline MLB Betting

Like many other sports, the Moneyline bet is choosing who will win the game. (Team A or Team B)

For example, if the Moneyline bet has Boston Red Socks at +120 and New York Yankees at -140, the Yankees are the favoured team and you would need to bet $140 just to win $100. If you place a $100 bet on the Red Socks and they win, you would win a total of $120.

Betting on an underdog can provide significant winnings if they manage to pull off a win, but be mindful that with baseball that there’s always an opportunity for a comeback.

Run Lines

Run Lines are point spread bets, but the payouts do vary according to the money line odds. Baseball run lines are based on a 1.5 point spread. Bets require meeting a 1.5 point spread as well as predicting the correct decision, therefore the payout can be much bigger than just betting on the Moneyline.

Run lines can often have very different odds than Moneyline bets, as winning the bet requires meeting a 1.5 point threshold in addition to winning the game, and losing the game could still result in a winning bet if the team doesn’t lose by more than the spread.

MLB Betting: Totals

Baseball totals are based on the total number of runs scored in a game by both teams. You bet on whether the total runs will be over or under a number set by sportsbooks. If the O/U for Chicago Cubs and Pittsburgh Pirates is 9.5, you’ll need at least 10 runs scored to win the over and a total of 9 or less runs to win the under.


Parlays are multiple outcomes to win your wager. You can usually bet up to ten teams in a single parlay bet. However, you need to ensure that all outcomes are winners otherwise you lose the bet. Parlays can be risker as you need all the outcomes to occur, but the rewards will be much larger if it all pays off.

In the case of bad weather what we call a rain-out in baseball, a calculation or a tie, the selected game is reduced in the parlay to the remaining games. For example, If you had a 4-way parlay and one had a rain-out it would then turn into a 3-way parlay for the remainder of the outcomes.  

MLB Betting: Futures

MLB Future bets are made on outcomes that haven’t happened yet, giving you the option to make a bet on any possible outcome. Reckon the Cardinals will win the World Series? Or possibly the New York Yankees to win the American League? You can place a bet on that happening! Your selection must win the event outright to win the Futures bet. 

Prop Bets

Prop bets are considered as a fun bet that is placed which doesn’t affect the outcome of a game. The additional bets can be related to specific outcomes in a baseball game such as which team will be the first to score a run or first team to reach 5 runs. There’s plenty of options for prop bets that are a player or team performance bets.

MLB Betting: Bonuses

With a total of 162 games to play for each team, there’s plenty of action to keep you busy with bonuses while betting on your favourite team. 

First Inning Run Scored – This bet is on whether there will be a run scored in the 1st Inning. 

Double Result – A double result bet is offered on the score of a game twice. In baseball, the bet is based on what team will be leading the match at the end of the 5th inning and the final score.

For the bet to stand, the game must go 9 innings, or 8.5 innings if the home team is winning. Suspended games do not carry over.

Listed Pitchers Option

Since baseball odds are dependant upon the starting pitchers, the better will need to specify in the case of changes to the starting pitchers. You will have to specify between a few choices: listed pitchers, one pitcher, or action.

  • Action – This wager means the bet goes ahead regardless of the scheduled starters begin the game or not. All bets are on!  
  • One Pitcher – A bet against one specified pitcher, means the designated pitcher must start regardless of who the other pitcher who is starting. If the specified pitcher does not start at all, the bet is deemed “No Action” and the bet will be refunded.
  • Listed Pitchers – This option means that both pitchers who are scheduled must start the game for the bet to be valid. If one or both of the specified pitchers listed on the wagering ticket do not start, the wager will be deemed “No Action” and refunded.
