However, the game’s lingo might seem slightly confusing at first glance and leave viewers baffled. One such term that often creates a sense of confusion is LOB in Baseball. So, do you want to dig deeper into this term and understand what it exactly means? This comprehensive guide will walk you through everything you need to know about LOB or Left on Base. Scroll down and take notes. 

What is LOB in Baseball mean?

Nothing is more frustrating than watching your team get a leadoff double and unable to record another hit. Well, that particular instance is known as Left on Base or LOB. 

The term significantly refers to the statistic measuring of baserunners strands on base when the inning ends. LOB is primarily used on an individual game basis, leading to a team’s loss, with a common factor being runners’ lob. 

Simply put, LOB, or you can call it Left on Base percentage, evaluates how often a pitcher leaves runners on base. The concept of LOB in baseball tends to normalize across most pitchers over time. It’s worthwhile to take a closer look when a pitcher is above or below that mark. Left on Base is a widely used statistic, as it can evaluate hitters, pitchers, or sometimes the entire team. 

But while the term sounds simple enough, it often becomes a headache for the person measuring the player’s deviation from that norm. In case you’ve missed it, Baseball is about a team’s goal to score runs. Therefore, they never wish to leave runners on base at the end of the inning, as it often leads to a team loss and put all their efforts in vain. 

How to Calculate LOB in Baseball?

Now that you know the basics of LOB in Baseball, it’s time to find out how to calculate this important metric. Be mindful that there are different methods to calculate LOB for pitchers, batters, and teams. 

For Pitchers

LOB for pitchers is also known as Strand Rate and only counts when a pitcher completes an inning. This metric can be determined by dividing the number of base runners a pitcher leaves on base when the gameplay ends by the total number of base runners. 

The formula description is: (H+BB+HBP-R)/ (H+BB+HBP-1.4xR)

Don’t worry; calculating LOB for pitchers isn’t as complicated as it may look, and you can easily determine without even diving deep into the concept. To keep things simple, it’s advised to look at the box score and find how many runners a pitcher allowed to reach base and how many of them scored. Easy, isn’t it?

For Batters

It’s easiest to calculate LOB% for batters, as no special calculation is needed for them. All you have to determine is the total number of runners on the base each time a batter was up to bat and how many of them scored. 

Let’s understand it with an example. If a batter bats four times in a game and no runners are even on, there’s no need to carry out a LOB calculation. However, if a batter bats four times and four runners are present on the base, and the batter brings in 1 to score, the LOB% is 25%. 

For Teams

Want to calculate LOB% for teams? Well, it’s way more simple than pitchers and batters. In general, if a team has a lot of hits in a game but not a lot of runs, it means they left a lot of runners on base. And the reverse is also true. 

Remember that you don’t have to worry about leaving runners on the base if your team is scoring high and winning the game. Let’s understand it in a more simple way. Suppose the leadoff batter gets on base, then it simply outs the next three batters. However, they left 1 total on base as a team. 

LOB is a slightly more useful metric for evaluating a team’s collaborative efforts and offensive performance. Be mindful that driving in runners and not leaving runners on base is a team effort and shows whether they are ready to play in big tournaments. 

If a team has a high LOB% for a game, it indicates that they didn’t utilize many scoring opportunities. However, having a high LOB in Baseball doesn’t always mean the team in question had a bad game. You must be aware that the more hits a team gets in a game, the more runners it leaves on the base. All in all, a team needs to get hits in order to drive runners in. 

How Many Runners Get LOB in Baseball?

If you have recently shifted your interest toward Baseball, you must be wondering about the total number of runners who get LOB in a game. And while the answer varies widely, most team average between six to eight runners left on base per game. 

But since there is no official number available about LOB, this metric might seem confusing to a new person who has just started watching Baseball games. It’s often believed that if the batting team leaves a high number of runners on base, it signifies that players are not ready yet and didn’t drive in many runs.
