Power, not just contact
Slugging weighs hits by how many bases they produce, so a slugger with many home runs scores far higher than a singles hitter with the same batting average.
Why slugging measures power, not just hits
Slugging percentage weights hits by how many bases they produce: a home run counts four times a single. Calculated as total bases divided by at-bats, it captures a hitter's power in a way batting average cannot, since average treats a single and a homer identically.
Slugging, OPS, and overall value
Add slugging to on-base percentage and you get OPS, one of the most popular quick measures of a hitter's total offensive value. A high slugging percentage signals a dangerous power threat, which is why it sits at the heart of modern offensive evaluation.
Frequently asked questions
How is slugging percentage calculated?
Total bases (1×singles + 2×doubles + 3×triples + 4×home runs) divided by at-bats. It rewards extra-base hits, unlike batting average.
What is a good slugging percentage?
Above .500 is strong and .550+ is elite power. League average typically sits around .400.
What is a good slugging percentage?
Around .450 is solid, .500 and above is excellent, and the game's elite power hitters push toward .600 in their best seasons.
How is slugging different from batting average?
Average treats every hit equally, while slugging weights hits by total bases, so it rewards extra-base power that average ignores.
What is OPS?
OPS is on-base percentage plus slugging percentage, a single number combining a hitter's ability to reach base and to hit for power.
