What makes a good Slugging Percentage?

Batting average values all hits equally. Slugging Percentage (SLG) assigns a weighted value to each hit, giving a batter more credit for hitting a double, triple, or home run.

  • Total Bases (TB): A single is worth 1 base, a double is worth 2, a triple is 3, and a home run is 4. You add all these up to get Total Bases.
  • Can SLG be over 1.000? Yes! Because the maximum possible outcome is hitting a home run every time (4 bases per at-bat), the absolute maximum theoretical slugging percentage is 4.000.
  • Benchmarks: An average MLB slugging percentage hovers around .400. Hitting .500 or above usually means the player is an All-Star power threat. Hitting over .600 is incredibly rare and usually results in an MVP award.
  • Did you know? Babe Ruth holds the highest career slugging percentage in MLB history at an astonishing .690. Barry Bonds holds the single-season record with .863 in 2001!
