Slugging Percentage (SLG)
Total bases divided by at-bats. Measures power output per at-bat.
Full Definition
Slugging Percentage (SLG) measures a batter's power by calculating total bases per at-bat. Singles count as 1, doubles as 2, triples as 3, and home runs as 4. SLG is a better indicator of power than batting average because it weights extra-base hits more heavily. A hitter with a high SLG but low AVG is a power-first player, while a high AVG but low SLG indicates a contact-first hitter without much pop.
