MLB Betting Guide For 18+

18+ MLB Betting Major League Baseball was once the most popular sport in America and is still one of the top four professional leagues in the United States. Due to the sheer volume of the MLB season – which features 30 teams playing 162 games apiece – the oldest US sports league still commands incredible, dedicated interest from fans and gamblers all around the nation.

Our MLB betting guide for 18+ shows you how to get started placing wagers on games. Many states now offer domestic online sportsbooks, but the best way to place real money baseball wagers is to use an international 18+ sports betting site that legally operates outside of US jurisdiction. With that in mind, it’s time to take some BP at the best baseball outlets online.

Where Can I Bet On The MLB At 18 Years Old?

To put your best cleat forward and place your MLB best bets today, you can wager immediately at any legitimate international 18+ sportsbook operating online, no matter where you live in the United States. It is legal and safe to use these sites, and they all offer dozens of pro baseball lines on every single game, all season long.

In fact, there are literally thousands of chances to wager and win real money every day during the Major League Baseball season.

All the 18 and over sports betting sites we recommend have been in the industry for years, hold proper licensing or regulatory credentials in their gaming districts, and are authorized to accept US players’ baseball bets (and all other sports market wagers).

While some US states allow their residents to wager on Major League Baseball playoffs, World Series, and regular-season games at local sportsbooks, these often require you to be 21 or older, and they aren’t yet available to the vast majority of American baseball fans.

Are 18+ Online MLB Sportsbooks Safe?

Yes! However, you can’t trust just any old sportsbook. To get the best results, you need to put your ace out there on the mound, and that means signing up and gambling only with the best sportsbooks for 18 and older players.

All of the sites listed here fit the bill like a well-worn mitt. As long as you place your MLB bets with any of the reputable operators listed here, all you’ll need to worry about is that speedster on first stealing second, not some shady sportsbook stealing your hard-earned money.

Online Funding Options For 18+ Players

There are numerous ways to fund your online gambling account when playing at 18 and up sites, but it’s important that the method you choose works for your specific needs.

For example, if you just heard a juicy trade rumor and don’t have enough money in your account to place a timely wager for maximum payout potential, you need a way to get your account topped off in a hurry. Similarly, if there are several compelling games today and you don’t have enough to wager on each line that interests you, you’ve got to be able to fund your account ASAP.

Credit and debit deposits are instant options, but they aren’t always reliable (due to the UIGEA banking law that can interrupt offshore money transfers to legal sportsbook sites). As a result, the best way to get money into your account is to deposit with Bitcoin or another supported cryptocurrency.

In general, the following banking options are available at most top 18+ sportsbooks:

  • Bitcoin (BTC)
  • Altcoins (Litecoin, Ethereum, Ripple, Stellar, Bitcoin Cash, Dash, etc.)
  • Zelle-To-Bitcoin
  • MatchPay (PayPal, Venmo, Cash App, Zelle)
  • QB Direct (QuickBit)
  • Credit Cards (Visa, Mastercard, American Express)
  • Debit Cards
  • International Gift Cards
  • Cashier’s Checks
  • Bank Wires
  • Money Orders
  • Person-To-Person Transfers (P2P)
  • Account Transfers/Vouchers

Remember: Crypto deposits let you transfer money immediately, come with no added transaction fees, offer the best deposit limits, feature enhanced sportsbook bonuses, and are the only ways to claim same-day payouts. All other banking methods can take 3-5 days to process in either direction, so they’re more knuckleball than a fastball.

Online Betting Bonuses For 18 And Up

Online sportsbook bonuses are one of the best reasons to gamble on MLB baseball at the top 18+ sites we recommend. These are usually deposit match bonus options that can boost your bankroll by 50-100%, depending on the deposit method you use

Bitcoin and other cryptocurrency bonuses usually give you about twice as many free plays when you sign up when compared to what you’ll get with traditional deposits.

All of the top baseball sportsbooks offer new member bonuses, and many also feature account reload bonuses. Refer-a-friend promotions are also commonly available. All bonuses or sportsbook promos are 100% optional.

Betting On The MLB Playoffs

The MLB playoff schedule lasts for about a month on average, usually ending in late October or early November. With 10 teams making the cut (three division winners apiece in the AL and NL, plus four MLB Wild Card teams), there are plenty of postseason odds to choose from, and the high-stakes action is unrelenting.

Betting On The World Series

The World Series is one of the most popular events of the sporting season worldwide. All the top 18+ legal sportsbooks operating online have World Series betting odds for college and professional baseball posted year-round, with futures touting the favorites for next season quite literally after the final out on the field of play for the previous campaign.

If you want to wager on World Series odds, the best time to do so – the time when you’ll earn the most spit for your ball – is during the offseason. Once the season starts and teams begin to separate from the pack, World Series baseball betting payouts will decrease substantially for the best clubs in the league.

MLB Bet Types At 18+ Online Sportsbooks

  • Moneyline – For moneylines, you simply pick the team you think will win a given contest.
  • Runlines – These are baseball spread bets, just with a different name. Usually, the baseball run line is automatically set at -1.5 for the favorite and +1.5 for the underdog. Thus, the favorite must win by at least two runs, while the dog can lose by a run (or win outright) to win the bet.
  • Over/Unders – Also called totals, the over/under asks you to wager on whether or not the combined runs scored between both teams in a given game will be higher or lower than the number posted by your online baseball betting site.
  • 5-Inning Line – The five-inning line features straights, runlines, and O/U bets that have to do only with the results of a game after the first five innings. This is designed to emphasize wagerng on starting pitcher performances.
  • MLB Player Prop Bets – Player props are odds on things that a particular athlete will do within a single game, like how many strikeouts a given pitcher will throw, how many hits a given player will get, and so on.
  • Team Props – Here, you can gamble on things like how many total errors a defense commits, how many total hits an offense racks up, etc.
  • Futures – MLB futures are wagers on things like which teams will win their divisions, which club will win the AL or NL Pennant, and which team will win the World Series. You can also place baseball futures on player awards like Golden Gloves, Silver Sluggers, ROYs, MVPs, Cy Youngs, and more. The earlier in the season (or off-season) that you place an MLB futures bet, the higher the payout.

MLB Live Betting For 18+ Players

Because betting on baseball online allows you to maintain a constant connection to your sportsbook, you can get updated lines that shift dynamically during the games themselves, allowing you to wager from the first pitch to the final out.

Now, you can put money on shifting odds that update multiple times per inning, reflecting the momentum of the game itself. All of the best 18 and up sports betting sites offering baseball odds feature live options on every game of the MLB schedule.

18+ Mobile MLB Betting Apps

Nowadays, you can watch pro baseball games on the go, keep yourself updated with live scores via push notifications right to your smartphone, and more. In other words, you can partake of America’s pastime anywhere in America you happen to be!

As such, it only makes sense that you can also bet on MLB baseball using your iPhone, iPad, Android, or other mobile devices. You don’t even need to download any smartphone or tablet apps, because all the best 18 and up mobile sportsbooks use browser-based web app portals to handle all your portable wagers.

As long as you have a relatively current mobile device, an up-to-date web browser, and an Internet connection (Wi-Fi or cellular), you can make real-money MLB betting picks from the back seat to the cheap seats and everywhere in between.

Best MLB Betting Strategies

While every player will eventually establish their own process, for rookies stepping up to the plate for the very first time, this should be your official lineup of baseball betting tips and tricks:

  • Understand the rules of the game. Baseball rules run the gamut, and there’s lots of minutiae to be aware of that can affect how likely your wager is to pay out.
  • Study team records, including their wins versus losses, their ATS (Against The Spread) records, their home and away records, and more. Baseball is a numbers game more than any other sport, giving statistics-minded gamblers a big edge on the boards. Knowing your team’s place in the MLB standings can also help you understand how urgent a given win for them might be. Teams play better with their backs against the outfield wall.
  • Pay attention to all the starting lineups, and study each player’s numbers before every game. Baseball, remember, is a game of averages. Use that to your betting advantage.
  • Research trends to see how teams fared for the same odds in previous games, especially when matched up against the same opponents.
  • Stay up to date on MLB news so you can follow injury reports, starting lineup changes, and more. A late scratch on the mound can be the difference between a win and loss for your baseball wager.
  • Pay attention to each game’s venue. Different fields have different configurations, temperature profiles, atmospheric pressures, wind patterns, and so on. All these factors will help you determine the likelihood of various outcomes. A game at Coors Field in the thin air of the Rockies is likely to be higher scoring and feature more home runs than a game played in the Arizona desert at Chase Field.
  • Shop the lines between the different 18 and up online sportsbooks. While every site will have the same runlines (+/- 1.5) as a matter of course, straight moneyline payouts and totals will often be different at each book. Always place your bets with the books offering the best payouts on any given wager. Remember, there is no one book that always has the best odds for every contest.
  • Never risk more than you can afford to lose, and favor small wagers instead of risking large portions of your bankroll on any single outcome. The best rule is to spend no more than 3% of your bankroll on any individual line. We recommend risking even less than that.
