# What Is a Run Line in Baseball Betting?

In baseball betting, you may come across the term ‘run line’ or ‘win line’. Essentially, these are the two sets of numbers which determine whether you will win or lose a bet. The difference between the two is that the win line favors the team which has the most scoring opportunities, while the run line favors the team which is in the lead. So if you are backing a team with a low run expectancy, then you should go for the win, while if you are backing a team with a high run expectancy, you should go for the tie.

## The Odds And Betting Exchanges For The Game

When placing a bet on a baseball game, you will initially be presented with the betting odds. These will be the chances of your team winning the game. For example, if you bet on the Yankees with an even money bet (i.e. the line is even), then you will receive 2 to 1 odds (i.e. the betting odds are 2 to 1 in favor of the Yankees). To see how this works, consider the following: The Yankees have a base expectation of winning the game, which is 50% based on their regular season statistics. Based on that, and using the above formula, a wagering exchange may offer the following odds for the game:

• Odds of 2 to 1 (50% chance of winning)
• Odds of 3 to 1 (56.25% chance of winning)
• Odds of 4 to 1 (62.5% chance of winning)
• Odds of 5 to 1 (67.5% chance of winning)

These are the betting odds which you will see when placing a wager on the game. Keep in mind that the outcome of the game may change based on various factors. For example, if the game is tied at the end, then there is no clear winner based on the regular season statistics. In that case, the number which represents the ‘over/under’ or ‘point spreads’ for the game would be used to determine the final winner – essentially, it is a tie. In the example below, the point spread is 3 and the over/under is 8. Therefore, based on the above equations, the following odds apply:

• Odds of 3 to 2 (56.25% chance of winning)
• Odds of 4 to 2 (62.5% chance of winning)
• Odds of 5 to 2 (67.5% chance of winning)

You may be wondering why these numbers are important. Simply put, without them, you would not have a chance of winning or losing a bet. For example, if you bet on the underdogs, then you are essentially taking a shot in the dark. The only thing which could possibly happen is that your money would be refunded (minus your initial investment). However, since there is no exact science to sports betting, sometimes you may find yourself on the opposite side of the equation. Consider the following example:

• Odds of 7 to 6 (14.29% chance of winning)
• Odds of 8 to 6 (15.38% chance of winning)
• Odds of 9 to 6 (17.44% chance of winning)
• Odds of 10 to 6 (20% chance of winning)
• Odds of 11 to 6 (22.22% chance of winning)

In the above example, even though the underdogs have a low base expectation, they also have an extremely high run expectancy. Therefore, even though you may be backing a small team, you are essentially putting yourself in a position to lose. For this reason, it is always a good idea to look at both the odds and the win/run line to determine whether you will gain or lose based on the outcome of the game.

## What Is A Run Line In Baseball?

Before we delve into the specifics, it is important to understand what a ‘run line’ is in the first place. Simply put, a run line is the number which determines whether your team will score the fewest or the most runs during the course of the game. In the above example, if you believe that the Red Sox will score the most runs (i.e. 7 or more), then you should go for the under 7.5 runs line, while if you believe that the Red Sox will score the fewest runs (i.e. 5 or less), then you should go for the over 5 runs line.

## How Do You Calculate The Run Line In Baseball?

When you are calculating the run line in baseball, you will need to consider several factors. The first is the total number of runs which your team is expected to score during the course of the game. The second is the total number of runs which the opposing team is expected to score. Third is the current run expectancy, which is essentially the total number of runs based on the statistics of the previous game. Last but not least, you will need to consider the quality of the opposing pitchers and the weather conditions, particularly if the game is underway in the summer.

To illustrate, let us assume that you are backing the Red Sox this season and that their win expectancy is 70% based on the number of games which they successfully completed (4 games). In that case, you should look at the following numbers to determine their winning run line:

• Red Sox runs scored (3.5)
• Reds runs scored (3)
• Weather: Over 65 degree Fahrenheit (Cloudiness)
• Pitching Matchup: Red Sox vs. Astros (A team which they will play twice during the season – once at home, once away)

With the above numbers, it is determined that the Red Sox will score 3.5 runs per game on average during the course of the season. Therefore, if they play 12 games, then they will score 15.5 runs on average. As you can see, the above numbers do not guarantee that the Red Sox will win every game they play. However, this information is enough for you to make a smart guess. For example, if you want to make some money off the Red Sox this year, then going for the over 3.5 runs line is a good idea. Keep in mind that if the Red Sox do score 15 or more runs in a game, then you will automatically win the bet. In other words, the Red Sox over/under win line will be 15 or more runs.

## When Do You Calculate The Run Line In Baseball?

The run line in baseball is initially set just before the start of the game. Therefore, once the game has started, it is always a good idea to check the current run line for the game. If you are not sure where to look, then simply look at the top of the ESPN ‘News’ page. You will see a small box with the scores of the previous game, along with some news stories covering the game. If you see a headline which is particularly interesting or eye-catching, then read the article. This will usually provide enough information for you to figure out the current run line for the game.

One of the things which can be quite frustrating in sports betting, is when the bookmaker changes the line. This is quite common which leads to many customers being utterly confused. If you are the type of person who likes to keep track of the many line changes, then you should look into subscribing to an odds comparison website. This way, you will always know whether the line has been changed for a specific game, or if it is a permanent change. The subscription will also provide you with an alert when there is major news regarding the team or game you are betting on. Inevitably, this will lead to many happy customers.

## How Many Runs Should You Score In A Game?

When placing a bet on a baseball game, you will be presented with the betting odds for that game. These odds will reflect the number of runs which you are expected to score during the course of the game. As noted above, some bookmakers may also provide information on the run line for the game as well. Keep in mind that the more runs which you score, the better your chances of winning the bet. In other words, the higher your team’s run expectancy is, the better your chances of winning.
