What Does DP Mean in Baseball?

Published in Baseball Terminology 2 mins read

In baseball, DP is an abbreviation for Double Play.

Understanding the Double Play (DP)

A double play occurs when the defensive team successfully records two offensive outs during the same continuous play. This impactful defensive maneuver is often referred to as "a pitcher's best friend" because it effectively provides twice the benefit of a single out, helping a pitcher escape troublesome situations and limit scoring opportunities.

How Double Plays Occur

While double plays can be executed in various ways, they generally involve quick thinking, precise throwing, and coordinated teamwork by the defensive players.

Most Common Scenario

The most frequent type of double play happens on a ground ball with a runner on first base. In this situation:

  • The batter hits a ground ball.
  • The defensive team forces out the runner from first base at second base.
  • Then, they quickly throw the ball to first base to get the batter-runner out before they reach the bag.

Other Types of Double Plays

Beyond the common ground ball scenario, double plays can also unfold through:

  • Line Drive Double Plays: A fielder catches a line drive, and then throws to a base to tag out a runner who left the base too early or force out a runner who needs to tag up.
  • Force Play/Tag Play Combinations: One runner is forced out at a base, and another runner is tagged out or forced out at a different base during the same play. For example, a runner on first is forced out at second, and then a runner on third attempts to score and is tagged out at home plate.
  • "Twin Killings": A term sometimes used synonymously with double play, emphasizing the two outs achieved.

Impact on the Game

Executing a double play is a significant moment in a baseball game. It can instantly shift momentum, extinguishing scoring threats and allowing the defensive team to get out of an inning with fewer pitches and without giving up runs.
