How to Bet on Baseball: MLB Betting Guide

Betting on baseball starts with understanding three things: how odds are displayed, what bet types exist and how the run line works.

This MLB betting guide covers all of it, from reading a moneyline to placing prop bets and live wagers.

How to Read Baseball Odds

First, let’s take a look at how sportsbooks post odds for upcoming baseball games.

The image above shows odds for a Friday game between the Red Sox and Tigers.

There are two listings for the same game. You can discern from the date, time, and teams that all the odds pertain to the same game. The second line here is called an alternate line, which offers sports bettors the chance to bet on a larger point spread with odds updated accordingly. Knowing this is the perfect start to finding out how to bet on MLB games.

Types of Baseball Bets Explained

When you’re betting on baseball games, there are six main types of bets you can make: moneyline, run line, totals, proposition (prop) bets, futures and parlays.

Baseball Moneyline Betting

Betting on which team will win the game outright. Odds are displayed with a plus (+) for the underdog (the amount you win for a $100 bet) and a minus (-) for the favorite (the amount you need to bet to win $100).

Example: Yankees -150 vs. Red Sox +130. A $150 bet on the Yankees wins $100, while a $100 bet on the Red Sox wins $130.

What is the Run Line in Baseball

The run line for baseball is essentially an MLB point spread, but it’s almost always set at +/- 1.5 runs. You can bet on the favorite to win by more than 1.5 runs or the underdog to lose by less than 1.5 runs (or win outright).

Example: Dodgers -1.5 (+120) vs. Giants +1.5 (-140). A bet on the Dodgers wins if they win by 2 or more runs. A bet on the Giants wins if they win outright or lose by only 1 run.

Baseball Over/Under Betting (Totals Explained)

Betting on the total number of runs scored in a game by both teams. The sportsbook sets a line (e.g., 7.5), and you bet whether the actual total will be over or under that number.

Example: Over 7.5 runs (-110) / Under 7.5 runs (-110).

Baseball Prop Bets (Proposition Bets)

Wagers on specific events within a game that don’t necessarily relate to the final outcome. Examples include:

• Total strikeouts by a pitcher.
• Number of home runs hit in the game.
• Whether a specific player will get a hit.
• First team to score.

Here’s an example of what that might look like at your favorite sportsbook:

Total Bases Bet

Betting on how many total bases a player will accumulate in a game. Total bases are counted for every base a player takes with a hit.

Example: If Ronald Acuna Jr. had two hits on the night, one a single and the other a double, he would have three total bases. You could bet Acuna 3+ total bases or Over 2.5.

Baseball Parlays

Combining two or more bets into one wager. All individual bets (legs) must win for the parlay to pay out. Parlays offer higher potential payouts but are riskier.  

Baseball Futures

Wagers on events that will happen in the future, such as World Series betting, the league pennant, or individual player awards (e.g., MVP, Cy Young).

In-Game Betting or Live Betting

Live betting is exactly what it sounds like: the best sites for online baseball betting allow you to wager on games that have already started. Canadian baseball fans will soon be able to participate in live betting once online sportsbooks in Canada launch.

The types of bets you can make with live betting will be the same as the ones discussed above. But the odds will shift depending on the score and the stage of the game. You won’t be getting a handsome payout, and the juice (or vig) will be higher when you bet on the Yankees in the seventh inning when they’re up by four runs. Conversely, you can make a pretty penny wagering on comebacks.

Cut-Off Times for Placing Bets

Unless you’re in-game betting, you will need to place your wager by a certain time in order for it to be accepted by the sportsbook. For baseball games, the cut-off time is the opening pitch. But keep in mind that broadcasts can be delayed, and sites can take a minute or two to process wagers. Best practice is to get your bet in at least a few minutes early.

You might be wary about placing a bet too early, fearing that something big will happen to completely alter the outlook. After all, pitchers get scratched shortly before game-time on a regular basis. (You can’t expect those fragile little things to pitch threw a blister!)

You might not have to worry about that, depending on what site you’re using. Many will refund your money/void the bet if one of the listed pitchers doesn’t start. Read the terms, conditions, and rules of all sites carefully before you start betting!
