How We Rank MLB Betting Apps & Sites

Gaming Today ranks betting apps on a variety of factors, including sign-up bonuses, fast payouts, the quality of MLB odds, the time it takes to execute a live baseball bet, and the number of player props available.

We also consider security, customer service, and other key criteria to ensure only the best MLB sportsbooks are recommended.

What to Look For in MLB Betting Sites

There are many factors to consider when signing up with a top MLB betting site. They include:

Welcome Offers & Deposit Bonuses

We’ve highlighted some of the best and most established sportsbooks in the country, including sign-up bonus details for each sportsbook in this review.

But, for the best betting experience, Gaming Today recommends that you open an account at more than one sportsbook. Multiple accounts allow you to compare the best odds for all of your bets during the MLB season. Plus, you have a chance to cash in on more than one sign-up bonus.

Competitive MLB Odds & Lines

Sportsbooks use analysts to set the odds you see, so opinion still influences their decisions. Other factors can change the odds as you check with multiple operators to make a bet.

  • Timing — Player availability, weather forecasts, and other factors can influence the expected outcome of a game. Some companies will be a little faster to update the odds based on recent developments. Other companies might overreact to new information.
  • Competition — Make no mistake, sports betting experts keep an eye on their competitors. Sportsbooks often use slightly more favorable odds to bring in your business.
  • Specialized offers and odds — Instead of a bonus, sportsbooks will sometimes reward customers by boosting the payout of an upcoming event.

Futures odds (including winning the World Series) can carry some of the best variety of odds. Let’s compare the 2023 World Series odds from late July as an example. All figures are based on a $100 bet.

Team to Win the World SeriesBetMGM MoneylineCaesars Moneyline
Houston Astros+800+700
Baltimore Orioles+1400+1500

A Houston Astros bet carries better value at BetMGM because a bettor will win $800 if Houston goes on to claim the MLB crown. The same bet at Caesars wins $700.

But a Baltimore Orioles bet carries more value at Caesars where the wager pays $1,500 if the O’s wins the World Series. The same wager at BetMGM wins $100 less.

Variety of MLB Bets Offered

The best MLB sportsbooks offer several betting options for baseball. We covered futures above, but let’s look at the full list here:

  • Run Lines
  • Totals
  • Moneylines
  • First 5 Innings (F5)
  • Live Bets
  • Props
  • Parlays
  • Teasers

Ongoing MLB Promotions

Sportsbooks will have plenty of sign-up offers in late March to get you ready for Opening Day each year. Major League Baseball returns a week earlier in 2024 because the season opens on March 20 in Seoul, South Korea. By then, ESPN may integrate Sunday Night Baseball with an ESPN Bet sportsbook promo tailored to MLB games as well.

Late summer sign-ups have some merit too. Companies pump out sign-up offers to encourage new NFL bettors, but your first-time bonus can be used for baseball betting in most cases.

App Reliability and Ease of Use

The pitch clock has reduced the downtime for live baseball betting, so you’ll want a site that is easy, fast, and trouble-free.

Sportsbooks release new odds as each inning concludes. The best MLB betting sites — like BetMGM and Caesars — feature some of the best-in-class experiences with quick oddsmakers and terrific live betting experiences.

Deposit & Withdrawl Options

The best MLB betting sites offer a variety of payment methods for deposits and withdrawals. Some states do not allow you to use a credit card like Visa or MasterCard for a sportsbook deposit. You might face a higher interest rate using a credit card to bet as well. Keep that in mind. The cash advance interest rate will be a factor when you review your betting budget.

Other options include:

  • Online banking
  • PayPal. There are several PayPal sports betting sites as it is one of the most popular and widely used online payment methods in the world.
  • Visa/MasterCard debit cards
  • ACH (e-Check)
  • Wire transfer
  • PayNearMe

App Availability

The best free MLB betting apps are available in more than 30 US states and the District of Columbia. Check Gaming Today’s updated list of states with legal sports betting to determine if a baseball sportsbook is available to you.

Customer Support

Top baseball betting sites offer customer support using online chat, email, and phone options. Try the “live chat” option first. It can be the most efficient selection when you have a question or need assistance.

Tips for Choosing the Best MLB Betting Site

The best MLB betting app varies depending on what you seek in a betting experience.

  • Which sportsbook offers the best baseball odds?
  • Who has the best MLB betting promotions?
  • Which company has the highest number of MLB betting options?

You’re in good hands with any of the top MLB betting platforms listed here.

Click the ‘Register’ or ‘Sign Up’ Button to Set Up Your Account

The process takes just a couple of minutes but it helps to have some personal information handy. You’ll need to provide proof of age and identity.

Enter Information That Confirms Your Identity

Your address and date of birth can be confirmed by uploading a photo of a driver’s license or state-issued ID. Once the sportsbook verifies your identification documents, you’re almost ready to deposit and start making bets.

Verify Your Location

Sportsbook sites and apps use geolocation services to confirm your location when you log in or try to place bets. If the geolocation technology determines you’re outside of state lines, you’ll be blocked from baseball betting on the app in that state. State laws mandate that you must be within state borders at the time of a bet.

Complete Your Registration With a Deposit

You have several different deposit options that instantly put funds into your account. Be sure to put at least the minimum amount required by the sportsbook to match their welcome offer.

PayPal provides one of the most reliable ways to deposit at an online sportsbook. Other methods include ACH/eCheck, credit cards, and debit cards.

Be careful with credit cards. The credit card company may treat your sportsbook deposit as a cash advance at a higher interest rate. Higher interest rates will cut into any winnings you might enjoy. It will add to the expense of a bet if you lose as well.

Make sure you’ve downloaded the sportsbook app from App Store (Apple users) or Google Play Store (Android users). If you use a browser, be sure to bookmark the site on your desktop, tablet, or laptop computer.

Place Your MLB Bet

Sports betting apps allow you to wager by simply clicking on the odds of your choice. Moneyline, point spread, totals, parlays, in-game betting, and more are at your disposal.

Be sure to follow the instructions if you are using a first-time bonus offer — you’ll want all of the perks that come with being a new customer.

Once you’ve clicked on a bet, the wager will appear on your bet slip (usually at the right of the screen). Confirm the bet — and any bonus offers — one more time on the bet slip to make the wager official.

Remember to Cash in Your Bonus Bets

Many sportsbooks add bonus betting credits to your account as part of their introductory offer. They can be quite generous for a first-time sign-up. But, those credits often come with an expiration date. If you don’t use them in time, they’ll disappear from your account. Be sure to double-check the terms and conditions.

Most Popular Types of MLB Bets

Once you’ve signed up, it’s time to start placing baseball bets. The most popular types of MLB bets include run lines, moneylines, and totals, but there are fun ways to bet on every aspect of the game.

Run Lines

Run lines are called point spreads in other sports, and they are a very common bet. If the Cubs are a 1.5-run favorite, it will appear as (-1.5) in any game information. With a -1.5 bet on the Cubs, just winning the game isn’t enough. The team needs to win by two runs or more for your -1.5 bet on the Cubs to pay out.

If the Mets are 1.5-run underdogs, the spread will appear as (+1.5). This means you can win on a Mets bet even if New York’s NL team loses the game. They simply can’t lose by two runs or more. A one-run loss is fine at +1.5 because that means the Mets covered the spread.

Most run lines are set with half-run odds — the hook — to establish a clear winner and loser. If the Mets’ spread is +2 and they lose by two runs, that’s a push at the sportsbook. You get your money back, but you don’t win anything.


Moneyline bets are among the most common wagers a bettor can make. They’re often the first numbers you see when you explore baseball betting lines for the MLB game you have in mind.

Numbers for favorites and underdogs are based on a $100 system, but you can place a bet for other amounts.

  • An underdog will have a “+” symbol. So, a bet on the White Sox to win at +125 means you’ll win $125 on a $100 bet.
  • Favorites will have a “” symbol. If the Diamondbacks are -140 to win, that means you would need to risk $140 to win $100.

Gaming Today’s moneyline calculator is easy to use. It can help you with the math based on amounts other than $100.

First Three-Inning (F3) and First Five-Inning (F5) Bets

This MLB wager revolves around either the first three innings or the first five innings of a game. The goal is to pick which side will be in the lead once the first three innings (F3) or first five innings (F5) are in the books. Click on the game you have in mind to find the F3 or F5 run lines. Ties are possible for this type of bet, so use our three-way calculator to research your potential payout.


Moneylines and spreads ask you to pick a team to meet the betting expectations. A total — also called the Over/Under — is a bet on the final score regardless of who wins.

An MLB total might look like this:

  • O 8.5 (-110)
  • U 8.5 (-110)

That means you’ll need to risk $110 to win $100 on the total points scored. If you bet the Over, a 6-3 outcome wins because the final score adds up to 9 runs. The Under wins if the final score adds up to 8 runs or less.


Prop bets are wagers that have nothing to do with a game’s outcome. Examples include:

Blake Snell strikeouts

  • O 7.5 (-140)
  • U 7.5 (+110)

Shohei Ohtani hits

  • O 1.5 (-140)
  • U 1.5 (+110)

If you think Snell will strike out at least eight hitters, a $140 bet on the over wins $100. A $100 under bet on Shohei Ohtani means you think he’ll have one hit or less. You’d win $110 based on the moneyline.


Futures bets are high-risk, high-reward wagers that focus on a season instead of a game.

The lines are typically displayed in a moneyline format. A trade deadline LA Dodgers bet to win the World Series sits at +450. So, a $100 bet would win $450 at the sportsbooks you use for MLB futures bets.

But, you don’t have to bet on an eventual champion.

The same sportsbook may have a “Padres to make the playoffs” or “Astros to win the AL West” bet for the ongoing season.

Many sportsbooks work with state regulators to add other betting options as well including:

  • Live betting
  • Round robin bets
  • Parlays
  • Same-game parlays
  • Teasers and
  • Early cashouts

MLB Betting Sites FAQ

What are the best betting sites for MLB?

Baseball is a popular summer sport to bet on with games played almost every night of the week. Some of the best options for MLB wagering include BetMGM, Caesars, FanDuel, BetRivers, Bet365, and DraftKings. Each of these sportsbooks offers terrific bonuses to new and existing customers, competitive odds, and user-friendly mobile apps.

Can I bet on MLB games online legally?

Online MLB wagers are available to fans in all states with legal sports betting. You can bet on MLB games if you are of legal age and physically located within a region with legal online sportsbooks.

If you can influence a game outcome (umpires, managers, and players for example) or have professional ties to the sports betting industry, you may be restricted. Gamblers who are on a restricted list also will not be eligible.

Where can I bet on MLB games online?

Legal sports betting is available in more than 30 US states. Look for baseball betting to grow as online gambling expands into new markets. MLB is a major sport, so count on your favorite sportsbook to have betting lines handy.

What’s the best way to bet on baseball?

The pace of baseball is great for live betting, but run lines are available well before the first pitch. You can also place futures bets at any point throughout the offseason, regular season, and throughout the playoffs.

What is the most winning baseball bet?

Like most sports, baseball can be unpredictable so there’s no such thing as an easy bet. Review pitching matchups and starting lineups before giving moneyline wagers a try. Use an implied probability calculator to discover your percentage chance of winning based on your bet’s odds and always do research on the latest player transactions, injuries, weather, and other factors that may impact the result of your wager.
