Baseball Interference Rules & What Happens When Broken Rule

Baseball is one of the most popular sports in the world, with millions of fans and players. However, with its complex rules and regulations, it can sometimes be confusing for new players and spectators. One of the most challenging aspects of baseball is understanding the interference rules. In this article, we will provide a detailed explanation of baseball interference rules, including the different types of interference, the consequences of interference, and how to avoid it.

What is Interference in Baseball?

Interference is when a player, coach, or spectator obstructs, impedes, or hinders another player’s actions on the field. Interference can occur in different ways, and it can significantly impact the outcome of a game.

Types of Interference

There are four main types of interference in baseball: batter interference, runner interference, fielder interference, and spectator interference.

  1. Batter interference occurs when the batter interferes with the catcher’s attempt to make a play or if the batter hits the ball while outside the batter’s box.
  2. Runner interference occurs when the runner interferes with a fielder’s attempt to field a ball or if the runner interferes with a fielder’s throw to a base.
  3. Fielder interference occurs when a fielder interferes with a runner’s attempt to advance to a base or if a fielder impedes a batter’s ability to hit the ball.
  4. Spectator interference occurs when a spectator interferes with a play by reaching onto the field or distracting a player.

Baseball Interference Rules

  1. Batter Interference: If the batter interferes with the catcher’s attempt to catch a pitch, it is considered batter interference. The batter is called out, and any runners must return to their previous bases.
  2.  Catcher Interference: If the catcher interferes with the batter’s swing, the batter is awarded first base, and any runners must return to their previous bases.
  3. Fielder Interference: If a fielder interferes with a runner’s attempt to advance, the runner is awarded the next base they would have reached if the interference had not occurred.
  4. Spectator Interference: If a spectator reaches the field and interferes with a ball, the umpire may declare the ball dead and award any affected runners the bases they would have reached without interference.
  5. Umpire Interference: If an umpire interferes with a play, the play is declared dead, and the ball is considered dead. The umpire may award any bases they deem appropriate.
  6. Coach Interference: If a coach interferes with a play, the umpire may award any appropriate bases and eject the coach from the game.

It’s important to note that interference can occur in various ways, and umpires have some discretion in determining whether interference occurred and how to enforce the rules.

Consequences of Baseball Interference:

The consequences depend on the type of interference and the situation in which it occurred. In most cases, the umpire will declare interference and call the play dead. The runner or batter will be declared out, and any other runners will be returned to their previous base. If the interference occurs during a play that would have resulted in a run, the run will not count.

In addition to the information we have discussed above, there are a few more things to keep in mind when it comes to interference in baseball. Here are some additional tips to help you understand the rules and avoid interference:

  • Interference can be intentional or unintentional. Even if a player did not mean to interfere with another player, it could still be called as such if it hinders the other player’s ability to make a play.
  • Umpires have the discretion to determine whether interference has occurred. The call may be clear-cut in some cases, while it may be up to the umpire’s interpretation in others.
  • In some situations, interference can be beneficial to the defensive team. For example, if a runner interferes with a fielder attempting to field a ball, the umpire may call the runner out, even if the fielder would not have been able to make the play otherwise.
  • Spectator interference can be particularly challenging for umpires to manage, as they have limited control over the behavior of spectators. If a spectator does interfere with a play, the umpire may declare interference and call the play dead. Still, it can be challenging to identify the offending spectator and determine the appropriate action.

How to avoid interference:

To avoid interference, players, and coaches must be aware of their surroundings and stay within the boundaries of the game. Batters must stay in the batter’s box and avoid swinging at pitches outside. Runners must stay in their lane and avoid interfering with fielders. Fielders must avoid blocking a runner’s path or contacting a runner when unnecessary.


Interference is a crucial aspect of baseball and can significantly impact a game’s outcome. By understanding the different types of interference, the consequences of interference, and how to avoid it, players, coaches, and spectators can enjoy the game while staying within the rules. Remember, interference is avoidable, and it is up to each player to do their part to ensure a fair and competitive game.
