What does slugging percentage measure?+
Slugging percentage (SLG) measures a batter's power by weighting hits according to the number of bases they produce: singles count as 1, doubles as 2, triples as 3, and home runs as 4. It's total bases divided by at-bats.
How is slugging percentage different from batting average?+
Batting average treats every hit the same regardless of how many bases it produces, while slugging percentage rewards extra-base hits proportionally more. A batter who hits all home runs will have a much higher SLG than batting average, while a singles-only hitter will have SLG equal to batting average.
Why can slugging percentage exceed 1.000 while batting average can't?+
Batting average is capped at 1.000 because a hit can only count once per at-bat. Slugging percentage totals up to 4 bases per hit, so a batter who homers in every at-bat would have a SLG of 4.000, far exceeding the 1.000 ceiling of batting average.
What's considered a good slugging percentage?+
In modern MLB, a SLG above .500 is considered very good power production, .450 is above average, and elite power hitters can exceed .550 or .600 in a strong season. League-average SLG typically sits somewhere in the low .400s.
How is slugging percentage often combined with OBP?+
Adding on-base percentage and slugging percentage together produces OPS (on-base plus slugging), a widely used single number meant to capture both a hitter's ability to reach base and their power. It's a rough combined metric rather than a precisely derived formula, but it correlates strongly with run production.
