What Is Slugging Percentage In Baseball

What is slugging percentage in baseball? It seems a tough definition with complicated calculations. Worry not; the article will explain it simply with examples.


What is slugging percentage in baseball? You’ve probably encountered the phrase slugging percentage when you’re a baseball enthusiast. Slugging percentage (SLG) is a metric used to measure how well a baseball player hits, particularly for power positions. 

The overall total of bases a batter hits each at-bat is measured by slugging percentage. The slugging percentage differs from the batting average in placing importance on different hits. 

Let’s not waste time more; find out the difference thoroughly below.

What Is Slugging Percentage In Baseball?

Slugging percentage (SLG) is a stat given to measure how well a hitter or batter hits. It is calculated by the total bases of a batter per at-bat. The slugging percentage is distinct from the batting average in that it applies a different weight to certain hits. 

A home run, for instance, is assigned a larger score compared to a single. Meanwhile, in the batting average, all hits of a batter are given the same value regardless of single or homerun. 

The statistic helps determine our ability to obtain extra-base hits such as home runs, triples, or doubles. To make it clear, let’s look at the calculation below.

How Is Slugging Percentage Calculated SLG In Baseball?

As mentioned above, slugging percentage (SLG) is a batter’s hitting output in baseball stats. Here is the formula to calculate it. 

Slugging percentage formula (hinh sua)

AB is the total number of at-bats for a player. Meanwhile, HR, 3B, 2B, and 1B are the number of home runs, triples, doubles, and singles, respectively.

Take Babe Ruth as an example. In 1920, Babe Ruth got 172 hits. There were 54 home runs, 9 triples, 36 doubles, and 73 singles. The total at-bats were 458. Thus, the calculation will be (73×1) + (36×2) + (9×3) + (54×4)= 388 and SLG = 388/458 = 0.847. It was Ruth’s slugging percentage. 

As we can see from the formula, the slugging percentage is different from the batting average. The batting average is computed by dividing the total number of hits by the number of at-bats. 

Though a double is not precisely worth twice as much as a single in terms of scoring runs, the stat is still one of the finest judges of power.

Why It’s Called Slugging Percentage?

The phrase slugging percentage is a way to quantify the amount of power a batter generates. When we achieve a high SLG percentage, it suggests we make a lot of powerful hits. 

The phrase “slug” or “slugger” describes a player who hits with a lot of power. That explains why the power measurement is known as the slugging percentage. 

The Purpose Of Slugging Percentage?

The main purpose of slugging percentage is to calculate the power a batter generates. A high slugging percentage indicates that the hitter produces more extra-base hits. 

The batter or hitter’s slugging percentage ultimately grants them a ticket to a better player significance. It means the stat adds to the team’s probability of winning. A good slugging percentage leads to more scored runs, which is how to win games. 

Given the on-base and slugging percentage, the slugging percentage has around 80% influence on winning. Plus, the hitter’s slugging percentage performance enhances his income value.

What Is A Good Slugging Percentage?

A slugging percentage is a number that is heavily influenced by a player’s hitting style. When we are contact hitters, we will likely not achieve an extraordinarily good slugging percentage. It is because our hits will not be rated the same as power hitters. 

We will likely possess a good slugging percentage once we are power batters. However, a good slugging percentage should normally be 0.450. 

A slugging percentage of 0.550 or more would be exceptional, and anything above 0.650 would be extraordinary. A 0.350 slugging percentage is considered to be poor. 

Who Created Slugging Percentage?

Henry Chadwick established a metric in 1867. It was the foundation for the contemporary slugging percentage. The recent slugging percentage employs total bases per at-bat. Meanwhile, it is per contest, as Chadwick’s statistic applied in the 1800s. 

The current slugging percentage was introduced by the American League in 1946 and the National League in 1923. Chadwick, a sports writing and baseball statistics pioneer, was years ahead of his time in his conviction.

Henry Chadwick

He believed hits merely did not convey the complete picture of a batter’s performance. The first documented slugging percentage application was on Ralph Kiner’s Bowman card back in 1952. 

It mentioned that he was the slugging percentage leader of the National League the previous year. However, it was in 1981 that slugging percentage often showed up on the baseball card back.

Frequently Asked Questions

Who Had The Highest Slugging Percentage All Time?

You might be curious about which player has the greatest overall slugging percentage. With a lifetime slugging percentage of 0.6897, Babe Ruth holds the record for the best slugging percentage. 

Ted Williams comes in second with a career record of 0.6338. Lou Gehrig ranks third with 0.6324, and Jimmie Foxx ranks fourth with 0.6093.

Is Slugging Better Than Batting Average?

Although batting average is a valuable measure for assessing how well a player bats at the plate, it is not comprehensive. Batting average, for example, does not account for the times a hitter gets to base via hit-by-pitches or walks. 

It also does not account for hit type (home runs, triples, or doubles). Thus, slugging percentage correlates to team runs better than batting average.

Is 1.000 A Good Slugging Percentage?

A 1,000 slugging percentage (SLG) is extremely good. It’s generally regarded as good if it’s greater than 0.450. A slugging percentage of 0.550 or more would be exceptional. Even the player with the highest slugging percentage possesses 0.6897.
