OPS+ is a statistic used in baseball to measure a player’s overall offensive performance. It is a combination of two statistics – On-base percentage (OBP) and Slugging percentage (SLG). OPS+ also adjusts for a player’s ballpark and league average. It is a great tool for comparing players from different eras, as it takes into account the offensive environment. In this article, we will discuss what OPS+ is and how to calculate it.

## What is OPS+?

OPS+ is a statistic that combines the two most important offensive statistics – On-base percentage (OBP) and Slugging percentage (SLG). It is used to measure a player’s overall offensive performance. OPS+ is also adjusted for a player’s ballpark and league average. This means that it takes into account the offensive environment in which the player is playing.

OPS+ is a great tool for comparing players from different eras, as it takes into account the offensive environment. It is also useful for analyzing a player’s offensive performance compared to the rest of the league.

## How to Calculate OPS+

To calculate OPS+, you will need a player’s On-base percentage (OBP) and Slugging percentage (SLG). You will also need to know the league average for OBP and SLG. You can find these numbers on a number of websites, such as Baseball Reference.

## Once you have these numbers, you can calculate OPS+ using the following formula:

**OPS+ = (OBP/League Average OBP) + (SLG/League Average SLG) – 1**

For example, if a player has an OBP of .400 and a SLG of .550, and the league average OBP is .330 and the league average SLG is .450, then the player’s OPS+ would be calculated as follows:

**OPS+ = (.400/.330) + (.550/.450) – 1 = 1.212 – 1 = .212**

This means that the player’s OPS+ is .212, which is higher than the league average.

## Interpreting OPS+

Once you have calculated the OPS+, you can use it to compare the player’s offensive performance to the rest of the league. A player with an OPS+ of 100 is considered to be average, while a player with an OPS+ of over 100 is above average, and a player with an OPS+ of under 100 is below average.

For example, if a player has an OPS+ of 120, this means that the player is 20% better than the league average. Similarly, if a player has an OPS+ of 80, this means that the player is 20% worse than the league average.

## Conclusion

OPS+ is a great tool for comparing players from different eras, as it takes into account the offensive environment. It is also useful for analyzing a player’s offensive performance compared to the rest of the league. To calculate OPS+, you will need a player’s On-base percentage (OBP) and Slugging percentage (SLG), as well as the league average for OBP and SLG. Once you have these numbers, you can use the formula provided to calculate the player’s OPS+. You can then use the OPS+ to compare the player’s offensive performance to the rest of the league.
