Legal US Online Baseball Betting 2024

USA Flag With Baseball

Legal baseball betting is one of the most popular sports gambling markets in the USA, due mainly to the game’s lengthy seasons. Placing a wager on a Major League Baseball contest is most popular, but other pro baseball leagues are covered by legal online sportsbooks. These include the Korean Baseball Organization (KBO) and Nippon Professional Baseball (NPB). You can also bet on NCAA college baseball at most books, but minor league baseball betting is usually not offered.

Regardless of what kind of baseball betting you prefer, you can find it at legal online sportsbooks operating offshore. MLB betting comprises most of the market, but whichever kind of ball you like best, you’ll be able to take your cuts with reputable sports betting operators.

Just make sure you’ve got only the best books in your starting lineup, using our online sportsbook reviews to ensure that whichever service you choose, you’ll be getting fastballs instead of spitballs. As long as you make like pine tar and stick with the books we recommend, you’ll be leading the league in RBI and ROI!

Is it Legal to Bet On Baseball In 2024?

Online baseball betting legality can vary from country to country, but placing a wager on a professional baseball team is primarily a US activity. Currently there are no federal laws which prohibit online gambling for the US individual, and the current laws in place are there to regulate the online gambling transactions handled by Internet sportsbook operators. These laws affect website owners and operators only, and since the vast majority of US states have not commented on Internet gambling one way or another, legal offshore companies provide that service.

Simply put, betting on baseball games online is legal for US citizens as long as the sportsbook they use is located, and legally operated outside of the United States. We list several of the more trustworthy and secure online baseball betting options available to US and international players here on our website, but only after undertaking a thorough and demanding review process.

Legal MLB Betting

MLB betting is the king of the hill when it comes to gambling on America’s Pastime. With 30 teams and a season spanning 162 games, that means bettors have some 2430 contests on which to wager – and that’s before the MLB Playoffs and World Series! With live betting added to the mix, each game has literally hundreds of different betting lines to choose from.

On average, avid baseball fans can expect a season slate of up to half a million different wagering opportunities when betting on MLB action with the best online sportsbooks. Bettors and Sabermetricians agree: The MLB is truly a numbers game!

Legal College Baseball Betting

NCAA baseball is popular in the US, but it doesn’t generate the same kind of betting interest that college football and basketball games do. Nevertheless, the best sports betting sites do offer select regular-season contests, particularly for the biggest conference rivalries.

Naturally, all books go big on their odds for the College World Series, which is when college baseball betting really gets into the swing of things.

Legal International Baseball Betting

International professional baseball leagues have been growing in popularity in the US, and that means that legal betting sites have started to include odds on their games as a matter of course.

The two biggest leagues outside of the MLB for baseball worldwide are the KBO and the NPB.

Korean Baseball Organization (KBO)

KBO Baseball logoThe Korean Baseball Organization, or KBO League, is by far the most popular sports league in South Korea.

The league was founded in 1982 and is comprised of 10 teams playing a 144-game season. Each team plays each other team 16 times, giving the KBO tremendous parity and offering bettors a very useful slate of data.

The KBO championship is called the Korean Series, and many of the league’s top players go on to play in the MLB.

Nippon Professional Baseball (NPB)

NPB Baseball logoOutside of the MLB, Nippon Professional Baseball (NPB), colloquially referred to as simply “Japanese baseball,” is the most well-known international variant of the game. Many former MLB stars continue their careers in Japan, and the nation has given the Majors some of its brightest stars, like the legendary Ichiro Suzuki, 2009 World Series MVP Hideki Matsui, and current superstar two-way player Shohei Ohtani.

In 2021, Ohtani became the first player in MLB history to be selected to the All-Star Game as both a pitcher and a hitter (DH). After the season, he was also the 19th unanimous MLB MVP (and ninth unanimous AL MVP). But even at just 27 years old as of the 2022 MLB season, Ohtani still has a long way to go to knock Ichiro off as the most dominant NPB-turned-MLB player of all time.

The NPB features 12 teams each playing a 146-game season, culminating in the Japan Series (aka Nippon Series).

Common Types Of Baseball Bets

All sports betting is, in general, variations on a theme. That is, if you’re familiar with the bet types for one sport, you’ll be familiar with those for any other.

When it comes to the most common baseball betting lines, you can expect your sportsbook to offer the following:

  • Run Line – The run line is the baseball point spread, and the favorite is almost always posted with a -1.5 run line, while the underdog will have a +1.5 run line. In other sports, the spread will vary based on the strengths and weaknesses of the teams in question. In baseball, the 1.5-run spread is industry standard.
  • Straight Moneyline – Straight bets use the moneyline to designate favorites and underdogs, and bettors simply pick the winner and are paid out according to the odds. Favorites have a negative moneyline (how much you must risk to win $100), while underdogs have a positive moneyline (how much you stand to win on a $100 wager).
  • Totals – Also called over/under bets, baseball totals simply ask bettors to pick whether the combined final score between both teams will be higher than (“over”) or lower than (“under”) the number set by the sportsbook.
  • 5-Inning Lines – The five-inning line is a baseball bet where gamblers choose which team will be leading after five innings. This tends to take relief pitching out of the equation, allowing bettors to give more weight to starting pitcher projections.
  • Props – Proposition bets can be player or team based and have to do with in-game statistical performances. A common baseball player prop you’ll find at most books is the over/under on how many strikeouts the starting pitcher will rack up. Meanwhile, a common team prop is an over/under on how many errors a given club will commit in a game. Props can also be of the yes/no wager format.
  • Futures – Baseball futures are wagers on far-off events, like division winners, pennant winners, and championship winners. You can usually place these bets year-round, with odds paying out substantially more the earlier such bets are made. Futures can also include player awards, like ROY, MVP, etc.
