What is MLB?

Major League Baseball (MLB) is the biggest baseball league in the world. Baseball is the national game of the United States, and the MLB league is home to astronomical amounts of money.

MLB consists of two leagues: the National League and the American League. Both NL and AL have three separate divisions, for a total of six divisions. In total, there are 30 teams in the MLB league, and all of them play 162 games during the regular season. So one MLB season offers bettors thousands of opportunities to place winning bets!

Below you can find all the MLB clubs and their divisions.

Why bet on MLB?

If you've never bet on baseball and MLB before, you might wonder why to start now. Don't bother your head with that question anymore because here are a few good reasons for MLB betting:

Baseball betting explained

In the following chapters, we will go through some of the specifics of baseball betting. We will introduce baseball betting markets such as baseball betting run lines and baseball live betting. We also give tips on things to look out for when betting on baseball. 

MLB baseball betting lines

MLB is a major league for betting sites, and you can bet on it in several different markets. The most common and popular market with MLB betting is moneyline betting. Other markets favoured by bettors are spreads, outrights, and live betting. However, bookies provide dozens, if not hundreds, of different markets and odds for individual matches. 

MLB money line betting

Baseball moneyline wagers are straightforward wagers on the outcome of the game. For example, if the moneyline had the Red Sox at 3/2 and the Yankees at 1/2, the Yankees are the favourite, and a £50 bet would net you £75. If you put £50 on the Red Sox and they win, you would win £125.

Total runs

You may already be an experienced NHL bettor and over/under is a familiar term. Total runs in baseball are betting on whether there will be more or fewer runs in a game than the limit set by the bookmaker. You can also bet on total runs per team (team totals).

Discover best baseball betting sites

Run lines

MLB run line betting is practically the same as a handicap bet on any other sport. The most common run line for baseball is -1.5/+1.5. With a 1.5-run line, you can bet on the favoured side to win by at least two runs. If you bet +1,5 run-line for the underdog, your bet wins if the team loses by no more than one run or wins the match.


The pitchers are the star players on the baseball fields and the superstars of the sports world. That's why it's natural that you can bet on the pitchers' efforts in baseball games. Most bookmakers allow bettors to wager on the number of strikeouts a particular pitcher records during the game. Strikeout betting follows the basic rules of over/under betting.

MLB live betting

Live betting is the best way to add excitement to watching live sporting events. With MLB live betting, bettors can bet on strikeouts, home runs, how the ongoing innings end and countless other scenarios.

NPB betting

In the wake of MLB, one of the favourite baseball leagues is Japan's NPB (Nippon Professional Baseball) league. Betting on the NPB is quite similar to MLB, but there is one significant difference. Matches can end in a tie in the NPB. In moneyline wagers, this usually means that the result is "push", and the stakes will return to bettors.

Another thing to consider is that the average number of runs scored in NPB is lower than in MLB. Two things contribute to this:

  1. The baseball used in the NBP is slightly smaller than in the MLB, and its grip favours the pitcher.
  2. The league has only 12 teams in two six-team groups. The teams and players know each other's style of play very well.

NCAA baseball betting lines

All sorts of college sports, for example, volleyball, are popular in the US, and NCAA sports are also interested in bettors living in the UK. NCAA baseball is one of the most popular college sports, and it is possible to bet on the league's games at baseball betting sites.

NCAA baseball betting lines, markets and odds follow the same pattern as in MLB. NCAA baseball betting is, therefore, "easy" in that sense. However, it's worth remembering there are 300 teams in the NCAA baseball regionals and more than 64 teams in the final tournament, and the players are not professionals. The skill levels of the teams vary a lot, and you will see mistakes in games that you don't see in professional fields. These are things to keep in mind when considering NCAA baseball betting.

Best MLB betting strategy & tips

No betting strategy is 100% bulletproof or guaranteed to win. Although, there are certain things that baseball bettors can do to increase their chances of making a profit.

Here are some of the key features to pay attention to:

The MLB season includes almost 5000 games when each team in the league plays as many as 162 regular season games. According to the statistics, even the weakest teams in the league win between 50 and 60 games during the season.

So if you bet on the same underdog all season and only half of your bets hit, you could make a profit, thanks to the underdog's higher odds.

However, it is not worth betting on the underdog in every situation. For example, an underdog away team with a few loss games in the back might not be worth playing.  In this case, it may even be a good decision not to bet on the match in question. Baseball betting odds favorites vs underdogs

This point is related to the previous underdog betting. MLB has teams like the Boston Red Sox, NY Yankees, NY Mets and Chicago Cubs that are very popular and well-known. The general public bets on them just for fun, without much justification. This betting behaviour lowers the odds and reduces the return rates, which means more attractive odds for the underdogs.


Baseball is a team sport, yet the importance of individuals like the pitcher is higher than in other sports. In all its simplicity, baseball is a nine-inning battle to see which team's pitcher can out-hit the hitters.

It's crucial to know which of the pitchers will start the match. You also have to note whether the pitcher is right or left-handed and whether the opposing line-up is primarily lefty or righty.

In addition to the starting pitcher, it is a good idea to think about and look at the statistics to see what the pitcher's ongoing form is and if there are any injuries behind him. You can find current information on starting pitchers on the Baseball reference page.

Longtime Baltimore Orioles manager and MLB hall of Famer Earl Weaver summed up the importance of the pitcher back in the 1960s to the Los Angeles Times as follows:

Nobody likes to hear it because it's dull, but the reason you win or lose is darn near always the same - Pitching
Earl Weaver


The topic of home-field advantage is one that every sports bettor in every sport brings up. It's worth looking at this in MLB as well. Back in 2009, an article published in the Baseball Research Journal stated quite clearly that "Throughout baseball history, the home team has won approximately 54 per cent of the games played"

Even in 2020, when baseball games were played in arenas that were empty owing to the COVID-19 pandemic, the situation of home advantage remained the same. According to a study by West Virginia University, the home fielding ratio in 2020 was the same as in 2019.

The main reasons for the home advantage are considered to be that the home team is batting second in the innings and the favour given by the umpires to the home team. The statistics on umpiring are interesting as research shows that the home advantage was also present in the 2020 season when there were no fans watching.

Last but not least, MLB bettors should check out the weather conditions in the stadium. The weather effect is a real deal - even the prestigious Massachusetts institute of technology (MIT) has published a study entitled "Understanding the relationship between weather conditions and home run rates in MLB."

Here are a few facts about the impact of weather in MLB:

  • Wind effects -> 1 mph increase of wind travel ball 3 feet longer
  • Temperature effects -> an increase in temperature of 10 degrees boosts the ball's flight distance by 1%
  • Air pressure effect -> a decrease in air pressure of 1 inch boosts the ball's flight distance by 1,5%.

All the weather changes mentioned above also work in reverse, of course. In cold rainy weather, the trajectory of the ball naturally shortens, and the number of runs is likely to decrease. The weather statistics are quoted from Robert K. Aidar's book The Psyhics of baseball. 

Here are some examples of the worst weather conditions for MLB games:
