Understanding Baseball Batting Metrics

How is Slugging Percentage (SLG) calculated?

Unlike batting average, which counts all hits equally, slugging percentage weighs hits by the number of bases they earn: a single is worth 1, a double 2, a triple 3, and a home run 4. The sum of these bases (Total Bases) is divided by official At Bats. Walk and hit-by-pitch appearances do not count as official at-bats.

Why is On-Base Plus Slugging (OPS) so important?

OPS is the mathematical sum of On-Base Percentage (OBP) and Slugging Percentage (SLG). It has proven to be one of the most reliable indicators of a team's run scoring capabilities. A league average OPS is around .720, whereas an elite player (like Aaron Judge or Shohei Ohtani) can surpass .900 or 1.000 in a season.

What counts as an official At-Bat (AB)?

An At-Bat represents a plate appearance where the batter either strikes out, puts the ball in play, or reaches base on an error. Walks (BB), Hit by Pitch (HBP), Sacrifice Hits, and Sacrifice Flies (SF) are excluded from official At-Bats because they represent a batter's patience rather than power outcomes.
