Major League Baseball betting is pretty common with American sports bettors, however, you’ll find that not as many do run lines as those who wager on the money line. While some people can consider themselves seasoned veterans at this type of betting, for those who could be considered new may feel a little lost. Our job here is to explain run line betting so you’ll be able to bet without fear.

Run line betting in baseball

First and foremost, you have to understand that when it comes to run lines, you’ll be choosing teams much like you would when you do taking money lines. For those that might be familiar with betting when it comes to the NFL, you’ll find that in a lot of ways run line betting for baseball is quite similar. When it comes to line for baseball, you’ll find that a run is one and a half. Once you place a 1.5 line bet, you’re able to bet that you believe the team you won will win by at least two runs if not more, or that the opposing team is going to lose by either one run or to win.

With that being said the favorite is then set at negative one and a half which means your team now has to win by two or more runs or cover the one and a half line. For those on the opposing team, they’d bet positive one a half which means they would be counting on your team to lose the game by at least one run if not less or they must completely just win the game. Almost all sites will allow you to bet at least one and a half on a line, however, there are different sites out there that will let you bid more, with different odds being placed upon the game’s outcome.

Run line betting examples

To give a bit of a better idea as to what some of the run line betting in baseball would look like, we’ll be using these two teams listed below to provide an example of what a bet might look like.

New York Yankees: 1.5+ (-150)

Chicago Cubs: -1.5 (+120)

As you can see above, the better is showing favor towards the Chicago Cubs winning as their line is placed at -1.5. The minus sign you see means that the better is pulling for Cubs which in turn means that the Yankees must win by at least two games or more. The positive one hundred and twenty number indicates that the Cubs must win by at least two or more games. 4

Likewise, in this example the Yankee’s are listed as the team that’s being bet against by expecting them to lose. The positive one and a half means that the Yankee’s either win by at least two games or must win the game all together. In this example, we used the New York Yankee’s as losing so the bet was negative one hundred and fifty.


Just like with any type of betting you need to have some sort of idea as to how you plan to bet in order to win. While there is a form of difficulty to run line betting, many ignore that and simply favor for choosing the team they believe that’ll win and place a bet accordingly while ignoring many of the other major components and thus costing themselves money in the long run. Many will also ignore the fact in the betting system, the home team always gets the favor, which plays against them too.

When betting on Moneylines, sports fan are often confused by the terms and terminology used on the betting websites. Therefore, it may come as a pleasant surprise to most readers that understanding Moneylines is much easier than the traditional bets. In simple terms, when betting on money lines, the only thing to consider is win or loss. Hence, players only need to bet if their team will win and the extent of win or loss does not matter.

Traditional bets most often offer specific probability of win or loss. For instance, a traditional bet may suggest that a specific team is favored by 2.5 points or 4 to 1 etc. However, Moneylines bet are presented in numerical digits, usually in increments of 5. In a typical scenario, a player may see the odds similar to such numbers as -110, +200 and -140 etc. For Moneylines fans, it is important to understand that negative (-) figures are associated with favorite teams and (+) figures are associated with underdogs.

Reading the Moneylines

For ease of understanding, it is easier to associate a Moneylines bet with $1. Therefore, a figure of +130 will means that anyone betting on the team will get $1.30 if their team wins. Of course, different brokers have different terms regarding the minimum amount that you can wager. Still, $1 is a good benchmark to understand the Moneylines. In this scenario, if the minimum bet was $10, the player will get $13 for accurately predicting the winning team.

For negative figures, the Moneylines work in the opposite manner. For example, if the Moneylines suggest -130 for a specific team, considering that the minimum wager is $1, the player will need to pay $1.30. In this instance, the winning sum will be $1.

If the above example seems complicated, just remember that the positive figure e.g. +150 indicates the winning amount in relation to the bet. On the other hand, negative figure -150 tells the player that it the minimum amount that they need to pay in relation to the bet. Hence, if the minimum wager is $1, +150 will mean that the player will win $1.50 if their team wins. In addition, the player will also get $1, which was initially invested as a wager.

On the other side, if the figure indicates -150, it simply suggests that the player will need to wager $1.50 to win $1.00, considering that the minimum wager is $1. If the player wins, they will get $1, the winning sum, and the initial wager invested, which was $1.50. In this instance, it is interesting to note that the negative figure will always require higher amount to place a wager compared to the winning sum. It is due to the fact that negative MoneyLines are always associated with favorite teams. Since, favorite teams are more likely to win, it makes sense to give smaller amount in return.

Overall, just remember that a positive figure indicates that the player will win that specific amount; whereas the negative number indicates that the player will need to pay that amount to win the odds.

MLB (Major League Baseball)- is a professional baseball organization. MLB organization is made up of the American League and the National League. Baseball has many abbreviations, acronyms, numbers and statistics and one has to know them to understand the baseball language. I will give a list of some of them to help the readers have an easy time anytime they come across these acronyms.

On Base Percentage /Batting Average /Slugging Percentage

On Base Percentage is the Measure of the player’s rate of reaching base to plate appearances. Batting Average is the measure of a player’s rate of recording hits to make outs. Slugging Percentage is the measure of the total bases accumulation rate to make outs by a player.

Range Factor

The range factor value is arrived at by multiplying by nine the number of chances (putouts +Assists) and dividing by the number of defensive innings.

Baseball is America’s pastime, and, like all sports, there are a number of rules to the game. One of the most misunderstood rules in baseball is the infield fly rule. So, I’m here to help explain a rule many fans don’t understand.

To be perfectly plain, the infield fly rule was introduced to do one particular thing, and that’s to keep the defending team from dropping fly balls on purpose in order to turn double or triple plays. If this rule didn’t exist, then teams would be dropping fly balls all the time. That is not how the game should be played.

Here’s something neat about this rule. After a ball is hit and popped into the air, the batter will be out whether the ball is caught or not caught. Now, ball players in the major leagues rarely misplay a fly ball in the infield, but, the rule is still there if an infielder for the opposing team wants to get a little tricky.

The rule exists since if a defending player were to consistently drop fly balls, it would not be a good show of sportsmanship. In effect, it would be almost like cheating. And, that’s not good for the game, and I believe the fans wouldn’t like it either.

What about batters that have a lot of speed, like the great Ricky Henderson? Opposing teams knew that Henderson was fast, as he stole a lot of bases. And, he made it look easy. Defending teams could drop fly balls to get those really fast players off the bases. So, having the infield fly rule is there to keep some integrity in the game.

See, if a really fast batter stole second, and then a big hitter with a great average came to the plate and was walked, then here we have an interesting scenario. The next batter up could hit a pop fly, and the infielder who would be making the catch could “accidentally” drop it, and force an out at third base. That way, the fast player is off the bases, and slower players are left on. Not in good sportsmanship, right?

But, to be clear about the rule, I can sum it up. To invoke the infield fly rule, there must be less than two outs, and there must be a force play at third base. So, either there are runners at first and second base, or, all bases have runners.

So how is this rule used? Well, if the above conditions exist, and a batter has hit a pop fly, then the umpire will point to the sky to indicate the infield fly rule has just been used. So now, the batter is out automatically, and it doesn’t matter if the ball is dropped or not. He’s out.

The infield fly rule is pretty easy to understand, but, most people don’t know what it is or when it’s used. It keeps some integrity in the game, and keeps cheating and trickery at a minimum.
