How to Bet on the MLB: Baseball Betting Explained

With the MLB season in full swing, baseball fans have several opportunities to wager on MLB teams and players. On all MLB games, you can bet on the moneyline, a spread (called the run line), and the total for the game. Below are more details on these types of MLB bets and betting lines, whether you're using Massachusetts betting apps, online sites, or wagering at a retail sportsbook. 

MLB Run Lines

MLB run lines are baseball's version of a point spread. If the Red Sox are favorites on the moneyline against the Yankees, their run line would be Boston -1.5, meaning in order to cash a run line bet Boston would need to win by two or more. Conversely, you can also bet on the Yankees +1.5, so if the Yankees win outright or lose by just one run, a Yankees run line bettor would win. The vig on a run line is related to how big of a favorite the team is on the moneyline.

MLB Moneylines

Betting MLB moneylines is simply betting on who will win the game outright. If you think the Red Sox will beat the Dodgers outright, shop around and find the best odds on the Red Sox moneyline and take that bet.

MLB Over/Unders or Totals

Just like in other sports, you can bet on the total runs scored in an MLB game. If the Red Sox are playing the Orioles, and the total is eight runs, and you expect a higher-scoring affair, you would bet on the over. Conversely, if you think the game will be a pitchers' duel, betting the under would be the way to go. If there are fewer than eight runs scored, under-bettors win, and if there are more than eight runs scored, over-bettors win.

MLB Player Props

Player props are becoming increasingly popular in baseball betting. Sports betting apps have different odds for each bet type, so make sure to shop around to get the best price.

First Hit

Some sportsbooks offer the ability to gamble on which player will get the first hit of the game. In order for this bet to win, no other player can record a base hit before the player you selected did.

Homerun Odds

You can bet on who will hit a home run in any game. If you think Rafael Devers is going to go deep tonight at Fenway, look at all sportsbooks available in MA, find the book with the best price, and take the wager.

Total Hits

Sportsbooks offer markets on how many hits a pitcher will give up as well as how many hits a batter will have. If you think Justin Turner is in for a good day, you can bet on him to get one or more hits. If you think the Red Sox are going to do well against the opposing starting pitcher, you can get on the pitcher to go over his hits allowed line.


Strikeout prop bets are one of the most popular prop bets to place. On any given game, you can bet on either of the starting pitchers to have fewer or more strikeouts compared to the number offered by the sportsbook.

Total Pitches

If you didn't think MLB prop bets could get any more granular, well, they can! Some sports betting apps offer a market on how many pitchers a player will throw in their start.

MLB Team Props

Not only can you bet on player props, but you can also bet on team props. Here are some examples of team prop bets below.

Total Hits

A market offered by sportsbooks is how many hits a team will record in a single game. You can bet on if you think said team will have more hits than the post line or fewer.

Total Runs

Not only can you bet on total hits, but you can also bet on how many total runs a team will score. If you think the Red Sox will score six runs, and their team total is 4.5, you would be the over.


Spreads in MLB betting are known as the run line, and there are spreads for the full game and the first half of a game. Generally, full game spreads are 1.5 runs, and the first half (also known as the first five) are .5 run spreads.

MLB Futures Betting

Here are some MLB futures bets you can make even while the season is underway.

CY Young Winner

You can place a bet on which player will win the Cy Young award in the American League and the National League. Sportsbooks have different odds on a bunch of players, so line shopping when looking to place a futures bet is a must.


Just like with Cy Young winners, you can bet on who will win the MVP in the American League and the National League. Again, line shopping in this market is imperative.

Rookie of the Year

Most sportsbooks offer Rookie of the Year markets for the American League and the National League. If you think Masataka Yoshida should win the AL Rookie of the Year award, you can bet on it in Massachusetts.


Every MLB team plays 162 games, so any team that starts the season hot or cold can still make or miss the playoffs. MA sportsbooks allow you to bet on if a team will make the postseason while the season is in progress.

Win Totals

Have you seen a team that started out hot, but you think their hot start is a fluke? Since the team got off to a hot start, their win total is going to be higher than the opening line, and you can fade that team by betting the under mid-season. Alternatively, you can bet the over on a team that is currently underperforming if you think they will bounce back.

World Series Odds

Throughout the MLB season, you can bet on which team you expect to end the season as the World Series champion. World Series odds vary by the sportsbook, so shop around to make sure you get the best price on the team you think will win.

What Is The Best Way To Bet On MLB Odds?

The best way to bet on MLB odds is to find the sportsbook with the best odds for the bet you want and use that sports betting app to make the bet. By simply using our tool to look at all the available lines in Massachusetts, you can make yourself more on a winner or lose less on a losing ticket.

Taking advantage of bonus funds is a great way to get started, and BetMGM is offering new users $1000 in bonus bets that can be used to bet on MLB by using bonus code STATEBONUSMGM.

Line Shopping For The Best MLB Odds

Line shopping for the best odds is one of the most useful things any sports bettor can do. On a single wager, if you get a better price, that means you can either win more money or lose less money. Using our website, you can compare the odds of every MLB game at every operational sportsbook in Massachusetts so you can get the best available line.

If you want to bet on the Red Sox to win, you should look at our tool and find the best price, which is shaded in light yellow. Again, this is important because if the Red Sox do win, you are getting a bigger payout. If they happen to lose, but you got the best line, you would lose less money.

How To Read MLB Odds

MLB Odds are listed exactly the same way any other sports odds are listed. There is a moneyline for both teams, a spread that is known as the run line, and a total.

The team with negative odds is the favorite. The favored team will also be laying a run and a half on the run line. The team with positive odds is the underdog, and that team will be getting a run and a half on the run line.

Lastly, there is the total. The total is the number of runs combined by both teams in the game, and you bet on if there will be more or fewer runs than the listed total. Assume you want to bet on the Boston Red Sox against the New York Yankees. You will see Boston -150 on the money line meaning they are the favorite. You will also see Boston -1.5 with odds associated with that as well.

You will see the New York Yankees at +130 and +1.5 on the run line since they are underdogs. The number of combined runs is known as the total. If you think Boston wins outright, you can just bet the moneyline. If you think Boston wins by two or more, you can bet the run line. If you think the Yankees win or lose by fewer than two, you can bet the run line or the moneyline.

MLB World Series Odds

At the beginning of the season, the Los Angeles Dodgers were the favorite to win the World Series. Now, halfway through the MLB season, the Braves have the best odds in the National League, and the Rays have the best odds in the American League.

The Astros opened as the American League favorite to win the World Series, but their odds have dropped due to their poor start to the season. As we near the MLB playoffs, we will continue to provide updates

Red Sox World Series Odds

At the moment, according to different sportsbooks in Massachusetts, the Red Sox's odds of winning the world series vary from +8000 to +10000. This means a $10 bet at +10000 would return $1000. Boston opened the season with +3000 odds to win the World Series, so based on how they have played the first half of the year, oddsmakers are bearish on Boston's rest of season outlook.

MLB Odds And Baseball Lines: Final Thoughts

Sportsbooks often have different odds for the same games. As mentioned earlier, finding the best odds is important because it maximizes your gain on a bet and minimizes your losses.

All sportsbooks in Massachusetts have fair odds often, but these odds will vary. Our tool will show you the best odds available at all sportsbooks in Boston so you can make the best bet possible.
