(1(B) + 2(Bx2) + 3(Bx3) + H(Rx4))/AB.

To get the baseball SLG’s total base, you need to count the number of bases they earned from their hits. You add one extra base for each double, two for each triple, and three for each home run.

Slugging Percentage Vs. Batting Average: What’s the Difference?

Regarding the slugging percentage in baseball, we focus on understanding how these metrics are calculated and what they reveal about a player’s performance, focusing on the hits he makes.

On the other hand, the batting average also represents the number of hits a player gets in relation to their total at-bats, but walks and hit-by-pitches are included in the equation.

What is OBP in baseball?

On-Base Percentage (OBP) measures how often a batter gets on base per plate appearance.

This includes any time the batter gets a hit, walks, or is hit by a pitch. However, it does not include when a batter reaches base due to errors, the fielder’s choice, or dropped third strikes.

How effective is combining OBP and SLG?

In baseball, OPS percentage (On-Base Plus Slugging) is the combination of On-Base Percentage (OBP) and Slugging Percentage (SLG).

It’s effective as it is easier for statisticians and analysts to measure a player’s overall offensive performance. Adding these two metrics together gives OPS a more comprehensive view of a player’s skill based on his performance.

What is Slugging Percentage in Baseball?

Slugging Percentage is the number of bases a player safely reaches per at-bat. The recorded value only factors in hits, while excluding walks and hit-by-pitches in the calculation. The main difference between slugging percentage and batting average is that hits are not treated equally.

For example, when a player hits a home run, they’ve covered four bases in a single at-bat.

A single would only result in one base attained at-bat.

The player would increase their batting average percentage equally, regardless of the type of hit, even though they vary in strength.

Note that the home run guarantees an additional point on the scoreboard, while a single does not.

The only way a single drives in a run is if there are other runners already on base, or if the fielding team commits a string of errors on the play.

Meanwhile, the slugging percentage will take into considering each base the player successfully crosses during their at-bat.

Typically, your hardest hitters dominate the Slugging Percentage leaderboard.

What is a good Slugging Percentage in Baseball?

Since 1876, the average slugging percentage has fluctuated between the 0.300 and 0.440 range.

As of the last decade, the average SLG has hovered around the 0.400 range while peaking to 0.435 in 2019.

Anything above 0.400 SLG is my starting point for good slugging percentage.

So, I decided to dig a little deeper to see how the league balances out.

The clearest sign that a player will finish the season with a strong slugging percentage is if they are hitting above 0.300 in batting average with a high home run count.

As an example, take Barry Bonds’ numbers from 2001.

He managed a record-breaking 73 home runs, along with a 0.328 AVG while appearing 476 times at-bat.

While his home run record attracted the most buzz, he also set the record for best slugging percentage with 0.863.

Again, that means he safely stepped on any base 86.3% of his chances at-bat.
