What does DER mean in Baseball?

Defensive Efficiency Rating

DER is a slang term used in the baseball world. It’s a statistic that helps us understand how effective a team is defensively. Simply put, it shows how good a team is at getting defensive outs from their defensive opportunities.

Calculating the DER isn’t too complicated. You take the total number of hits that were allowed to be in play, but you don’t count any home runs. This number is then divided by the total number of defensive opportunities, which is any ball that’s been hit into play, again not counting home runs.

After you’ve done this division, you subtract the result from one. This gives you the DER. The lower the DER, the more efficient the team is defensively. This is a statistic that can really show how a team is performing on the field.
