MLB Betting Sites & Live Odds

mlb betting sites

Major League Baseball odds are one of the easiest ways for rookie bettors to get in the betting game. A 162-game regular season means multiple games almost every day from late March to October, plus the crescendo of division and wild card races that leads to playoff baseball and the World Series.

Boston Red Sox fans are, of course, passionate about the team and will be as excited about legalized MLB betting. MA bettors will also be able to bet on or against any team they want alongside dozens of MLB player props and futures.

If you want live-game betting there’ll be no shortage of that, either, from betting on a pitcher to strike out the next batter to betting on a double play to come and more. See below for how to bet on MLB online in MA (when it is eventually legalized) plus current live baseball odds.

Best MLB odds boosts and promos

Sportsbooks offer boosts and promos throughout the season to entice players. These odds boosts and promotions can be advantageous to a bettor during a 162-game season because they often give you more profitable odds.

In 2021, DraftKings Sportsbook offered a weeklong 50% odds boost for MLB bettors based on winnings across all markets. How did this work? During the promo week, say you bet $20 on the moneyline at +100. Instead of winning $20, you’d win $30 plus receiving your initial stake back.

The FanDuel Sportsbook app offers daily odds boosts for player props, moneylines and totals during the season. An example of a boosted proposition bet is 2021’s offer of the New York Yankees or Tampa Bay Rays to get a hit in their first plate appearance, from -120 to +150.

How to bet a baseball run line, moneyline or over/under

  • Run line: The run line is baseball’s version of a point spread bet. It’s a bet on a team to win by exceeding a certain margin of victory or to avoid losing by more than that spread number. Due to baseball’s scoring structure, the standard run line is 1.5. For example, if the Rex Sox run line is -1.5, you’re betting on the Red Sox to win by two or more runs. If the line is Boston +1.5, you’re betting on the Red Sox to lose by one run (or win by any score).
  • Moneyline: A moneyline bet is a bet on one side or the other to win the game. You choose what team you think will win, with potential winnings based on the odds at the time of your bet. If a sportsbook lists the Red Sox at -120, Boston is the favorite. You would have to bet $120 to win $100. If the odds have the Red Sox at +120, Boston is the underdog. You would win $120 by betting $100.
  • Over/under: A total bet on the combined score in a game. If the over/under is 7.5, and you bet the over, you need both teams to score enough runs combined to push the total to eight or more. If the final score in a game between Boston and Philadelphia is 5-3, you would win the bet. If you had bet the under in the example above and the final score was 3-2, you would win there, as well.

First five innings betting

According to 2020 data, MLB starting pitchers now average less than five innings a start. One of the most critical variables in a game is starting pitching, as the starters handle the ball more than any other player in a game.

Given how much pitcher usage has changed over the years, handicapping a nine-inning game based on starting pitching is much more challenging. With a bet on the first five innings, you can still focus on the starting pitchers and not worry about the bullpen carousel of the later innings.

You have to be careful, though. Discounting the strengths and weaknesses of a team’s bullpen and late-inning offensive trends could cause you to miss valuable bets on the board.

The odds work like a moneyline bet, with you choosing the team that you believe will be ahead after the first five innings.

MLB line movement

MLB lines move differently from sports like basketball and football. Those sports have byzantine scoring structures and a lot more offense, and in those games, you’ll see the spread number move more often because that’s the primary way people bet.

In MLB betting, you’ll likely see more movement on the moneyline and the odds numbers associated with the run line. A standard MLB run line is 1.5. You’ll rarely see that number move before a game.

Say the Red Sox play the Oakland Athletics at home, and Chris Sale is on the mound for the Sox. The sportsbook has the Sox as favorites, with -145 odds on the moneyline. Because you’re betting that the Sox will win by two runs or more, the odds associated with the -1.5 run line are -115.

Now, say the Sox announce that Sale will miss his start due to elbow discomfort. The spread will likely stay at -1.5, but the odds will change. The moneyline may shift to a number like -110, while the run line odds may jump to a positive number like +125 due to Sale’s absence.

MLB props and futures

Betting on MLB futures allows you to bet on a team before the season starts. You can make multiple future bets on the Red Sox before opening day, and you always have the opportunity to make new bets as the season progresses.

For example, you could bet on the Red Sox to win the World Series well in advance of them actually making the playoffs. On a futures board, you may see the Red Sox World Series odds at +1800. You also have the option to bet on them winning the American League pennant or the AL East at different odds.

Another team futures bet you can lock in before the season starts is the over/under on the team’s total wins. The sportsbook handicappers set the number of wins, and you can bet that the Red Sox will win over or under that amount.

Betting on individual players is also available via the MLB player prop odds boards. You can find odds on awards, like MVP odds and Cy Young odds for both leagues. You also have the option to bet on whether a power hitter like Rafael Devers will lead the league in home runs, hit more than 2 home runs in a single game, and much more.

Once the season starts, you’ll still have access to those preseason bets plus daily game props on virtually any player and team. Check the MLB tab of your sportsbook to see the prop bets available for each game.

MLB live betting

With online betting options and sportsbook apps, live MLB betting has never been easier. Why might you want to bet as the game is going on? It’s a way for you to leverage your baseball knowledge into winning bets.

Sites like FanDuel, DraftKings and BetMGM sportsbook in Massachusetts will adjust their in-game lines by the second. You may see a game where the Sox give up a few runs in the first inning, but you feel confident they’ll win. You’ll be able to grab odds that will be far more profitable when the Red Sox trail.

One of DraftKings’ best features is an integrated streaming platform for all account-holders with an MLB.com membership, so you can watch games and access stats directly.

What makes MLB betting different?

According to betting data, the NFL is the most popular option at sportsbooks. It makes sense. It’s the most popular sport, and most of the games occur on Sundays. But the massive exposure of pro football doesn’t help bettors much. Betting markets get tighter as they receive more exposure.

While baseball is America’s pastime, there are far too many games happening each night during a season for casual bettors to explore. That means you may be able to find under- or overvalued teams and better odds on a day-to-day basis.

It’s also an excellent way for new bettors to get their feet wet at legal Massachusetts sportsbooks. Unlike the NFL and NBA, the spread is primarily static (NHL betting lines are similar). You’ll also bet more moneylines and totals.

Another cool perk of baseball betting? The Grand Salami bet, where you the over/under on the grand total of all runs scored in all games that day.

As always, though, beware of scamdicappers or touts who profess they can tell you who will win an MLB game on any given day,
