Measure Raw Hitting Power (SLG)
What is Slugging Percentage?
Slugging Percentage (SLG) is the definitive measure of a baseball player\'s power. While Batting Average simply tells you how often a player gets a hit, Slugging tells you how much \"damage\" those hits do. By weighting doubles, triples, and home runs more heavily than singles, SLG provides a clear picture of which hitters are the most dangerous at the plate.
How to Calculate Slugging Percentage
The calculation is based on \"Total Bases\" divided by official at-bats:
(1B + 2×2B + 3×3B + 4×HR) / AB
Example: A player with 10 singles, 5 doubles, 1 triple, and 2 home runs in 50 at-bats has (10 + 10 + 3 + 8) / 50 = 31 / 50 = .620 SLG.
Slugging Benchmarks
In Major League Baseball, power standards have shifted over time, but these are the modern benchmarks for excellence:
- .550+ (Elite): The league\'s premier power hitters. Consistent home run threats.
- .450 - .550 (Great): A very strong, productive middle-of-the-order hitter.
- .400 - .420 (Average): The typical baseline for a Major League starter.
- Under .350 (Poor): Indicates a hitter with limited extra-base power.
Limitations of SLG
While SLG is great for measuring power, it has one major flaw: it completely ignores walks. A player who walks 100 times a year is extremely valuable, but their SLG won\'t show it. To get the most complete picture of a hitter, analysts often combine SLG with On-Base Percentage (OBP) to create OPS.

Frequently Asked Questions
What is Slugging Percentage (SLG)?
Slugging Percentage measures a batter's raw power by calculating the total bases a player earns per at-bat. Unlike batting average, which treats all hits equally, sluging percentage gives more weight to extra-base hits.
How is Slugging Percentage calculated?
The formula is: SLG = (Singles + (2 × Doubles) + (3 × Triples) + (4 × Home Runs)) / At-Bats. It is also often expressed as Total Bases / At-Bats.
What is a good Slugging Percentage?
.450 is considered excellent, while .550 or higher is reserved for the league's elite power hitters. The Major League average typically hovers around .400 to .420.
Can Slugging Percentage be higher than 1.000?
Yes. While extremely rare over a long period, it is mathematically possible to have a SLG as high as 4.000 (if a player hits a home run in every single at-bat). Barry Bonds holds the MLB single-season record with .863 in 2001.
