BetMGM was the first official betting partner of Major League Baseball, and since its inception, it has been very involved in the sport, going as far as building a sportsbook at Nationals Park in Washington, D.C. 

Also, BetMGM offers a wide array of player props and team props, so if you are the type of bettor who likes to dive deep and place detailed wagers, this is the place to go. 

BetMGM has risen to prominence as the top MLB betting site due to its offering of live streaming. Through the sportsbook’s platform, bettors can watch games as they happen, which allows them to make more informed betting decisions. BetMGM also features a lucrative welcome bonus, in which they reimburse your initial stake up to $1,000. They run MLB-specific promotions, like odds boosts, same-game parlays, and bonus bets, so stay tuned as they update this information constantly.

There are several features that have made Caesars Sportsbook one of the best choices available for MLB bettors. To start with, Caesars gives new customers a first risk-free bet of up to $1,250. Once you’ve created an account with Caesars and placed your first bet, if it is not successful, they will refund your wager up to $1,250. This credit will be granted as bonus bets. By joining the platform, you will also earn 1,000 Reward Credits and 1,000 Tier Credits for the highly sought-after Caesars Rewards program. Your betting activity will also accumulate points for this loyalty platform, and once you have enough points, you will be able to redeem them for accommodations or other travel experiences at any property that is owned by Caesars. 

Caesars also offers several odds boosts promotions daily, which allows you to maximize your winnings. This is in addition to MLB-specific profit boost tokens. For example, you can bet on a player to hit a home run in a game, and if your wager succeeds, Caesars will increase your payout up to 25%. 

Like BetMGM, Caesars also built a retail sportsbook at an MLB ballpark, located at Chase Field in Phoenix, Arizona. 

FanDuel Sportsbook

FanDuel ranks #1 in market share in the United States. It’s naturally a top choice for MLB betting. On both the App Store and the Google Play store, FanDuel has the top-rated sports betting app. This is complemented by an impressive desktop site, which provides users with an intuitive betting experience. 

FanDuel has made strides to position itself in the minds and hearts of baseball fans, building partnerships with iconic teams such as the Detroit Tigers, New York Yankees, and Chicago White Sox. The sportsbook has several MLB-specific promotions, like its Dinger Tuesday promo. If you place a pregame home run bet on any MLB game, FanDuel will give you $5 in Bonus Bets, up to $25, for every home run hit during the game. 

Other attractive features offered by FanDuel are its Daily Fantasy Baseball contests, where you can draft your team and win cash prizes daily. The sportsbook’s No Sweat First Bet is also attractive. If you place your first cash bet with FanDuel, and it is settled as a loss, you’ll receive your stake back in bonus bets up to $1,000

DraftKings Sportsbook

Loading DraftKings Sportsbook Banner...

Like FanDuel, DraftKings started as a provider of Daily Fantasy Sports (DFS). Therefore, it offers attractive contests, where you can pick your team and “step up to the plate for big cash prizes.” Also, DraftKings offers an extensive array of betting markets for MLB. Some of the wagers you can make include live bets on the result of the next pitch, the overall record of a plate appearance, live batter props, and live pitcher props.

DraftKings also has a variety of promotions available. For new customers, the sportsbook gives you 20% of your initial deposit in Bonus Bets, up to $1,000. In addition to that, there is the MLB Stepped Up SGP. If you place a qualifying Same Game Parlay through your DraftKings account, your profits can be boosted up to 100%. 

DraftKings has earned wide acclaim due to its top-notch user experience, along with its low deposit threshold. While other platforms have higher minimums, you can start wagering at DraftKings with just $5. 

bet365 Sportsbook

Originally founded in the United Kingdom, bet365 is working hard to increase its market share in the constantly-growing U.S. betting market. As of now, the platform is available in the states of New Jersey, Colorado, Ohio, Iowa, and Virginia, where new bettors can be eligible for a lucrative welcome bonus. If you bet $1 on bet365, you will receive $200 in bet credits, regardless of whether you win or lose your initial bet. 

Bet365 has specific promotions that are tailored towards baseball bettors. The top one is the Baseball Early Payout Offer. If you place a pregame moneyline bet on any MLB game, and your team gains a lead of 5 runs or more at any point of the game, bet365 will honor your bet as a winner and pay it in full. If your bet was combined in a parlay, it will be marked as successful, and the outcome of your parlay will depend on your other bets. This promo not only applies to MLB, but can be extended to the Japanese and Korean baseball leagues, so if you are a fan of international baseball, knock yourself out!

WynnBET Sportsbook

Loading WynnBet Sportsbook Banner...

Backed by the renowned Wynn Resorts brand, known for its luxury resorts and casinos around the world, WynnBET aims to bring the Las Vegas experience to sports betting. If you do not have a WynnBET account, you can claim a $100 Bet Credit bonus once you join the platform and wager your first $100. The outcome of your first bet doesn’t matter, you get the bonus bets whether you win or lose. WynnBET considers MLB one of its main betting markets, so it is common to see bonus bet opportunities for specific games and outcomes. 

BetRivers Sportsbook

Loading BetRivers Banner...

When it comes to MLB, BetRivers has several enticing promotions. Besides its 2nd Chance Bet, which gives you a bonus bet equal to your stake up to $500 if your first wager loses, BetRivers also has the Tuesday Home Run Insurance. If you place a qualifying wager on any player to hit a home run on any Tuesday game, you can receive your bet back–up to $25–if they record an extra base hit during the game. 

BetRivers also offers MLB Parlay Insurance. If you, as a bettor, have experienced the disappointment of losing a lucrative parlay because one game fell through at the last minute, this will appeal to you. When you place a qualifying MLB parlay of at least four legs with BetRivers, you can get your stake back, up to $25, if exactly one of your parlay legs is a loser. 

PointsBet Sportsbook

Loading PointsBet Sportsbook Offer...

The sports betting partner of NBC Sports, PointsBet has gradually increased its footprint in the United States. And through several MLB-geared promos, the sportsbook is hopeful to lure more prospective customers to its platform. 

For new users, PointsBet has the 5 Second Chance Bets bonus opportunity. To qualify, once you create your new PointsBet account, place a fixed odds cash bet daily for five days. For any of those bets that lose, PointsBet will refund your wager, up to $100 per stake. This means that if your first five bets were not successful, assuming each one was worth $100, you would still get $500 back in bonus bets. 

PointsBet also has several innovative features. Through its Lightning Bets, you can bet every play, pitch and run, and stay on top of the action as it happens. Also, when wagering on a same-game parlay, PointsBet boosts your odds so you can increase your profits. 

Unibet Sportsbook

Loading UniBet...

For new customers, Unibet has a special promotion that rewards them with a second chance bet up to $100. If you are in Pennsylvania, the amount you could receive goes up to $500. Once you create your Unibet account and make a deposit, place a bet. If you lose, the sportsbook will refund you. 

Founded in London, Unibet is one of a few European sportsbooks aiming to capture a slice of the U.S. market, leveraging its extensive experience in other countries to offer a wide array of odds and betting markets. Other promotions offered by Unibet include Same Game Parlay Insurance, which gives you a $10 bonus bet if only one of your legs loses, and the Level Up Parlay Booster, which can bolster your earnings up to 50%.

Factors to Consider When Choosing an MLB Betting Site

Since legal reform made it possible for sportsbooks to legally operate in the United States, companies that had a presence in different sectors–such as casinos, daily fantasy sports, and sports media–made it their goal to enter the market and become the sportsbook of choice for bettors nationwide. 

If you are wondering which site to choose for your MLB bets, know that at Lines, we highly recommend that you shop around for the best sportsbook. Since there are many factors that we consider when evaluating bookmakers, you need to decide which of those are the ones that matter most to you. 

We look at sportsbooks holistically, so you can make an informed decision.Browsing around different platforms will help you stay on top of the best odds, and in the long run, this can make a difference in your profitability as a bettor.

Reputation and Licensing

When choosing a sportsbook, reputation and licensing are two crucial factors to consider, as they help determine whether a sportsbook is reliable, trustworthy and in legal compliance. 

We prefer sportsbooks that are known for their integrity, fairness, and timeliness. The guidelines here are clear: we only work with sportsbooks that honor payouts, promptly process payments, and have more positive reviews than negative. While we understand that it is impossible to control the experience of every user and that there will always be clients who complain, the best sportsbooks will still garner praise and build a loyal user base. 

Then, there is the legality question. As the number of online bettors keeps growing, many platforms that have not been granted approval to operate in the United States might still be targeting viewers and bettors with advertisements offering deals and exclusive promotions. However, to protect your integrity and legal standing, we suggest that you only use platforms that have been legally authorized to operate in your jurisdiction. If you are not sure what the status of sports betting is in your state, check out this guide

Even platforms that have been granted permission to take bets in the United States are not allowed to solicit customers in every state in which sports betting is legal, and also, that there are certain restrictions to the types of bets available. For example, some states forbid wagers on collegiate athletes or in-state university teams. 

Range of Betting Markets

Something that we highly recommend at Lines is choosing a sportsbook that can match the level of detail with which you would like to place your wager. 

When we were describing the best sportsbooks for MLB betting, you were able to see that some baseball wagers can be extremely thorough, going down to the outcome of the next pitch. If this is the type of bet that you are interested in, make sure the markets you are looking for are available. On the other hand, if you are planning on placing the most common wagers–like the moneyline, run line, or total–then most sportsbooks will be able to cater to you. 

Also, there are sportsbooks that go beyond MLB. As mentioned, bet365 even goes as far as applying bonuses to the Japanese and Korean baseball leagues. It often happens that many stars from these international competitions end up playing for some of the top teams in America, so getting to know what is going on internationally is useful.

Competitive Odds and Lines

Before you decide on a baseball sportsbook, make sure you consider the competitiveness of their odds and lines. These directly impact the potential profitability of your wagers. 

In their quest to increase their allure to more customers, sportsbooks are going as far as making sacrifices on their fees in order to be appealing to more bettors. For example, WynnBET has a special initiative called Thursday Win Hour. Through the promotion, bettors that place their wagers within the specified hours on a Thursday will be able to access improved odds. 

Again, we highly recommend shopping around for the best odds. It is almost impossible that only one sportsbook will have the best odds all the time. And even though it might seem like a slight difference, over time, it can add up to a substantial improvement in your profitability as a bettor. 

User Interface and Experience

Betting should be fun and easy. We value sportsbooks that provide bettors with a seamless user experience. Both the mobile app and the web platform need to be user-friendly enough for anyone to quickly learn the navigation. Not everyone is tech-savvy, so good sportsbooks should display information clearly and transparently, allowing any new user to intuitively place their bets and navigate through the different betting markets and promotions. 

Bonuses and Promotions

Loading DraftKings Sportsbook Banner...

Every sportsbook that is legally authorized to operate in the United States has some sort of welcome bonus or promotion, whether it is a deposit match, a risk-free bet, or a second-chance bet. 

For example, FanDuel offers a $1,000 No Sweat First Bet Bonus, in which they refund your first stake in case it is not a winner. BetMGM does the same, and Caesars Sportsbook takes it even further, reimbursing up to $1,250 for bettors who are not lucky in their first wager. Usually these are awarded as bonus bets, which means that you cannot withdraw it as cash, but can put it toward new bets.

Other bonuses include loyalty programs (for example, Caesars Rewards and MGM Rewards), and promotional offers such as odds boosts, which increase your potential payout on a wager. As you find your way through different sportsbooks, you might find that they offer odds boosts for specific events to incentivize betting activity. In MLB, you can expect to see plenty of available bonuses as the World Series gets closer.

Deposits and Withdrawals

Nobody likes experiencing delays when receiving their payout after winning a bet or facing difficulties when making a deposit into their betting accounts. Since this is a defining criterion for bettors, sportsbooks have prioritized speed and agility in payments as one of their top features, recognizing the importance of offering multiple deposit and withdrawal options to accommodate user preferences. 

Before creating an account with a specific sportsbook, verify that they offer the payment method that suits you best. Commonly accepted options include credit and debit cards, bank transfers, digital wallets like PayPal and Venmo, and prepaid cards. Some sportsbooks also give the option of conducting operations in cash at one of their physical locations. 

Sportsbooks typically list their estimated processing times for both deposits and withdrawals. We strongly advise that you review these before signing up, and that you stay away from those bookmakers that have excessively restrictive withdrawal policies or long processing times. 

Especially if you plan on betting large amounts of money, payout limits are something to take a look at. Some sportsbooks limit the amount of money that you can win on a particular bet or within a specific time period, and also, how much they can pay out. 

Customer Support

Customer support is something that sportsbooks need to take very seriously, as it plays a key role in ensuring a positive and engaging betting experience. 

The first thing to look at in terms of customer support is the channels that the sportsbook can be reached through. Those that have the best customer support have a 24/7 live chat feature, as this enables them to promptly address any issues you might have. 

We consider it valuable when a company has several channels to handle inbound requests. For example, if you have any problems with your account, a customer support number that you can call is very handy. 

A sportsbook that makes it a priority to offer top-notch customer support will also optimize its response time. As a customer, waiting for extended periods of time is frustrating and harms the overall betting experience. When issues arise, a good sportsbook is able to provide a swift resolution. 

Commitment to Responsible Gaming

For several reasons, responsible gaming is an essential feature of a sportsbook, and a way in which betting enterprises demonstrate their commitment to the community. 

By offering mechanisms such as self-exclusion and deposit limits, sportsbooks protect their customers and promote responsible behavior. By doing this, they build long-term customer relationships, minimize harm, and create a positive image for the betting industry.

Types of Baseball Bets Allowed

For new baseball enthusiasts and seasoned bettors alike, there are several betting markets within MLB. Here, we explain some of the most popular ones, so that you can consider them for your next bet.


In baseball, as in every sport, the moneyline is one of the most popular bets. 

For a moneyline bet to win, you need to correctly predict the winner of a particular game. The margin is irrelevant. 

There are many scenarios in which the moneyline is an attractive bet, one of them is by spotting the underdog that will pull off the next upset. 

For example, if the Atlanta Braves, one of the top contenders to win the 2023 World Series, play the Washington Nationals, an underperforming squad, a bet on the Nationals is likely to yield an attractive payout. 

Run Lines

The spread, which in baseball is also known as the run line, is the way in which the sportsbook levels the odds for both teams. 

Let’s say that the Tampa Bay Rays are facing the San Diego Padres. A moneyline bet on the Rays might display significantly negative odds, potentially -300. 

With the run line, the bet would look like this:

  1. Tampa Bay Rays, -1.5 runs, -110
  2. San Diego Padres, +1.5 runs, -110

For a run line wager on the Rays to be a winner, the team would need to win by at least two runs. Conversely, a wager on the San Diego Padres could still be successful even if the Padres lose the game, as long as they’re within one run.

Over/Under (Totals)

Also known as a total bet, by wagering on the over/under line you are predicting whether the number of runs scored in the game will go over or fall under a certain number determined by the sportsbook. 

Let’s say the Kansas City Royals are playing the Colorado Rockies. The total is set at 8.5 runs. If you bet on the over, both teams need to combine for at least nine runs for your wager to be marked as a winner. 


A futures bet is a type of bet through which you can anticipate the outcome of a distant event. 

For example, when betting on the MLB, you can predict:

  • Which team will win the World Series?
  • Who will be the season’s Most Valuable Player?
  • Who will be the Rookie of the Year? 

Something that makes futures an exciting proposition is that you can place the bet before the season even starts. If you do this, you are likely to find attractive odds. 

Of course, once the season is underway, you are also able to place MLB futures wagers. The odds will fluctuate depending on how teams progress through the season.

Props Bets

Prop bets allow bettors to predict specific outcomes within a game. Through props bets, bettors can wager on individual player performances, team statistics, and even unique occurrences during the game. 

MLB prop bets include which team will score first, how many hits a certain player will record, and how many strikeouts a pitcher will have.

Some sportsbooks like to offer very detailed prop bets, and with the rise of live betting, you can even wager on the outcome of the next play. Shop around and find the prop bets that speak more to you, especially if you plan on watching the game. 


A parlay is a bet where you combine multiple individual wagers into one. 

For a parlay to be a winner, every bet must be successful. If one leg loses, the entire parlay is graded as a loss. The main advantage of a parlay is that it gives you the potential for a higher payout.

In a parlay, you can combine practically any bet, except for those wagers that have contradictory outcomes. For example, you cannot bet on the Boston Red Sox to win and lose in the same parlay, for obvious reasons. 

Even though parlays initially combined outcomes from different games–for example, the Astros defeating the Angels and the Marlins winning against the Mets–now, sportsbooks have heavily invested in developing the same game parlay modality. 

Through a same game parlay, you can combine two outcomes that will happen in one game. If the Yankees are facing the Red Sox, you can combine the Yankees to win on the moneyline and Aaron Judge to hit a home run in the same bet.

MLB Betting Odds

We’ve covered some of the main MLB betting markets and how they work. We’ve also mentioned which ones tend to have the best payout rates. 

Now, it is critical that you fully understand the odds. For you to be successful as a baseball bettor, you must become fluent in how odds are determined. 

If you are in the United States, most likely, you are looking at a dashboard that is displaying American odds. This is one of three formats in which sportsbooks display their odds, the other two being decimal odds and fractional odds. 

American odds list the outcomes that are most likely to happen–favorites–with negative odds. Underdogs are listed with positive odds. 

To help you estimate your winnings with American odds, these formulas are useful. As a note, when using the formula for negative odds, leave the minus sign aside. 

  • Payout with negative American odds = (100/Odds)*Wager
  • Payout with positive American odds = (Odds/100)*Wager

To explain further, here is an example. 

The Philadelphia Phillies are facing the Chicago Cubs, and you have wagered $50 on the Phillies. 

The moneyline odds are:

  • Philadelphia Phillies, -140
  • Chicago Cubs, +115

Profits for a $50 bet on the Philadelphia Phillies = (100/140)*50 = $35.71

In addition to your $35.71 profit, you would recover the $50 you wagered. This means that the total payout for a $50 bet on the Phillies, if successful, would be $85.71.

Odds to win the 2023 World Series

The Fall Classic is one of the most popular sporting events of the year. 

In 2022, over 12 million viewers watched the World Series. One of the most-watched games, 2016’s Game 7 between the Chicago Cubs and the Cleveland Indians, was witnessed by over 40 million people

Unsurprisingly, the MLB World Series is a top driver of sports betting activity. As of now, here are the most recent odds to win the 2023 World Series.

Atlanta Braves+370
Tampa Bay Rays+450
Los Angeles Dodgers+470
Houston Astros+950
Texas Rangers+1000
New York Yankees+2000
San Francisco Giants+2500
Toronto Blue Jays+2500
San Diego Padres+2700
Minnesota Twins+3000

When choosing the best sportsbook to place your MLB bets, numerous factors need to be considered.

It is critical to ensure that the platform you are planning to wager on is legally authorized to take bets in your state, as this will guarantee the integrity of your funds. 

After that, take a look at the variety of betting markets that the sportsbook offers, and determine whether it meets your needs, especially if you are the type of bettor who loves to dive deep into wagers like player props and team props, or if you plan on engaging in a lot of live betting and want to watch the games while you bet. 

Also consider the user-friendliness of the interface, the speed of the customer support department, and the ease of deposits and withdrawals. 

Welcome bonuses and ongoing promotions–like odds boosts and parlay insurances–are always well-received add-ons that will increase your enjoyment and boost your profits.
