There’s no question that baseball is America’s favorite pastime and it follows that online MLB betting makes it all the better. Sportsbook bettors that are new to the scene might be unfamiliar with the ins and outs of the MLB sportsbook scene. So below is a brief guide to bring you up to speed on the basics of MLB baseball betting, odds and different types of betting lines.

BetNow is one of the top sports betting sites that allows MLB bettors to participate and legally bet on baseball betting from the regular season up to the postseason. MLB bettors can find the most up-to-date sports betting odds and various betting lines surrounding the tournament.

Below you’ll find a comprehensive guide and information covering the ins and outs of online baseball betting that can help you understand major league baseball betting, betting value, and other things that are related to baseball betting trends.

The History of Baseball Betting

Baseball betting has been going on essentially since there was baseball. Betting was one of the main ways that the sport was always viewed by the general public. Of course, in the late 1800s and early 1900s, betting was very different than it was today. Yes, there were bookies, and people that you had to get the bet through.

As it was prohibited legally, you couldn’t exactly appeal to any sort of law if you were taken advantage of or lied to. As the sport evolved and Vegas rose to prominence, there were legal sportsbooks that people could avail themselves of, legal bookies, and so forth.

Today, baseball betting is better than it’s ever been. Instead of having to go to Vegas, Atlantic City, or even your local casino, you’ll be able to bet on the games you want to bet on from anywhere, just as close as your phone or computer.

Types of Baseball Bets

There are more ways to bet on baseball than ever before. With our site, you’ll be able to bet on the money line, the point spread, and the odds in just about every game. With many games, you’ll also be able to bet alternatives of those as well, should you so choose.

Additionally, you can bet “futures,” which are basically betting on what will happen through the course of the season, in the playoffs, and so forth. Prop bets are sometimes available, where you can bet on what a player or team is going to do.

The legalities of baseball betting have expanded greatly — baseball betting is legal in more places than ever before. But, that doesn’t mean that it’s legal everywhere. We always recommend checking out the legality of the rules in your area before you engage in betting.

Online MLB Betting Breakdown

The Major League Baseball season consists of 162 games for each of the 30 teams — 15 in the American League and 15 in the National League, with 29 teams in the USA and 1 in Canada. A total of 2,430 games played over roughly six months, plus the postseason.

The MLB betting season begins in spring sometime in March and continues until the fall, concluding in late September or early October. Afterwards the postseason begins, leading up to the World Series — the final series of the season to determine the best team in the world.

In February, pitchers and catchers report to Spring Training. There’s a “Grapefruit League” in Florida and a “Cactus League” in Arizona. You can find all of these betting options right here at our site — including the Boston Red Sox, the New York Yankees, and every other team with live odds.

First things first, you’re going to need to set up an account. Once that’s all done and set up, you’re ready to make some bets on MLB games. However, it’s important to have some basic understanding of how MLB betting lines work and which MLB odds you’ll want to jump on.

Types of MLB Betting Lines

The most common MLB betting lines consist of the money line (betting straight up), the run line (betting against the spread), and the over/under (TOTALs). The line begins on the left with the name of the team followed by the run line, then the over/under and lastly the money line.

TeamRun LineOver/UnderMoneyline
Pirates+1½ (-140)9½ (-110)+148
Cubs-1½ (+120)9½ (-110)-158

The odds on our site are created by professional handicappers who take many factors into account. Moreover, the odds adjust as circumstances change — a player is injured, someone is called up, and so forth. The calculated odds will shift when something happens.

Betting MLB Money Line

When you bet on the moneyline, you are simply betting on one team to beat another. In moneyline bets, you have a choice to place bets on the favorites or bet on underdogs. If you’re betting on the favorites, you will earn less money than you wagered if your bet wins, whereas winning an underdog bet will return more.

The Cubs are pegged as a -158 favorite, which means you need to wager $158 in order to win $100. A $158 winning bet on Chicago would net you $258 total (the original $158 wager plus the $100 in winnings).

Because the Pirates are the underdog, taking them straight up is more appealing. Since they’re facing + odds, you only need to wager $100 in order to win $148. A $100 winning bet on the Pirates would net you $248 (the original $100 wager plus the $148 in winnings).

Betting MLB Run Line (ATS)

Betting against the spread is a little more complicated than betting straight up but it’s still fairly straightforward. Instead of betting on one team to beat another, here you are betting on a team to cover the spread.

The run line is set at 1½ points. In order for Chicago to cover the spread, the Cubs must beat the Pirates by more than 1½ points. On the other hand, if the Pirates can avoid losing by less than 1½ points, they will have covered the spread.

Cubs win 10-8 — Won by 2 points, covered the 1½ spread. ✅
Cubs win 10-9 — Won by 1 point, did NOT cover. ❌
Pittsburgh wins 5-4 — Upset, Pirates covered. ✅

Betting MLB TOTALs

Unlike betting run line or money line, here you aren’t really picking one team over another. Instead, you are simply betting on the total sum of points that will be scored in a game. This is calculated by taking the points one team scored and adding it to the points the other team scored.

Sticking with the betting line we’ve covered, we can see that the over/under is set at 9½ points. So if you think more than 9½ points will be scored in this matchup, you would take the over. If you think there will be less than that figure, you would take the under. The over is always the top line and the under is always the bottom line.

Parlays

Betting Parlays are very popular because they take a relatively low-risk wager and turn it into a massive payout. Parlays work by allowing you to combine multiple bets into one. Naturally, you need all of your bets to come true in order for your parlay to be successful. Since this is quite difficult to accomplish, bookies really sweeten the pot with these types of predictions.

Props Betting

Proposition bets or prop bets are a type of bet that can be related to any stats within a game that doesn’t need to have a direct correlation to the final results or outcome. It includes player performances, exact scores, team win totals, and others. These types of lines can offer action on who will have a lead at halftime, what kind of game players will have, and everything in between.

Live Betting

Live betting allows baseball bettors to bet on a game as it unfolds, making both the game and your bets that much more thrilling. This is somewhat new to the scene but it offers the biggest thrills of all. Additionally, there are a ton of opportunities to find some winnings as you watch the game develop.

MLB Futures Betting

Futures betting is a great option with tremendous odds. If you feel confident about who will be winning the World Series, this is without a doubt the best way to go about betting on baseball. Here you can make lofty predictions way in advance and capitalize on some pretty eye-catching odds.

Baseball Betting Resources

The best betting resource for baseball is simply to watch the game, to know the game. The more baseball you see, the more you encounter it, the more you bet, the better you’ll get. Research and knowledge are critically important.

The best resources for learning about baseball are Major League Baseball’s home site, the respective team sites, and more. The phrase “regression to the mean” is one that so many first encountered through baseball — teams that start off very hot tend to “come back to Earth” as they become what they were thought to be.

Baseball Betting Tips & Strategy

First, remember: this is supposed to be fun. If it ever feels like it’s not fun, stop doing it. Research is always your friend — the more you know, the better a decision you’ll be able to make.

There really are no such things as “baseball betting systems” that you could rely on time in and time out. As with so much else in betting, you’re going to have to go with your research and, ultimately, your intuition.

Another important tip: remember, there are more bets than just the point spread and the money line. Take advantage of the “first five innings,” of the futures, and so forth. Those are great, often overlooked ways to make real money in baseball betting.

Money Management for Baseball Betting

The best and most important money management advice for baseball betting is the same for all kinds of betting: never bet what you can’t afford to lose. Eventually, the best teams lose, dynasties fall, and so forth. Even the best bettors will tell you that they lose plenty too.

Another important money management tip: go with a betting site that gives you some kind of free start or free bet. You want something where you’ll be able to get started with a bet that can launch your baseball betting on that site the right way.

Commonly Asked Questions about Baseball Betting

What’s the objective when betting on baseball?

To have fun, of course — and to win. You’re trying to predict what’s going to happen in a game, in the first half of a game, with a player, and so forth. Betting money that you’ll be able to predict correctly is the whole idea.

Is there a “House Edge” in baseball betting?

The house always gets the opposite of what you bet. For the most part, five percent is the actual “house edge.” You can calculate it by looking at the total amount of money returned to bettors and subtracting the total amount wagered.

Is baseball betting different than other sports?

Absolutely — because you get so many more opportunities. There are 162 games in the baseball regular season alone. That’s a lot of chances to bet compared to the NFL, where a team plays at most 20 games. More opportunities means more ways to win.

What are baseball betting odds?

It comes down to your bet and what kind you’re making. Odds usually come from the money line. You’ll see this as a ratio — -120, +200, etc. If you see a “-“, that team is the favorite. If you see a “+”, that team is the underdog.

How can I give myself the best chance to win?

If we go with the idea that “betting” is really “making a prediction,” you’re more likely to make a great prediction the more you know. Learn all you can about baseball. Before putting a bet down, really dig deep on the players, the teams, and matchup history.

What are some common baseball betting mistakes?

“Just guessing” is a big one. Not doing research, betting more than you can afford to lose, and “betting on streaks to last forever” are the most common mistakes. Perhaps the most common is not really learning the game before getting into the betting.
