Catcher's Interference

Also known as: catcher's interference, catcher interference, catchers interference, catcher's mitt hit my bat, catcher touched the bat, batter's interference, batter interference

Definition

Catcher's interference is when the catcher, or any fielder, interferes with the batter during a pitch, usually by touching the bat with the mitt as the batter swings. Under MLB Rule 6.01(c), the batter is awarded first base. If a play follows, the offense's manager can choose to take the result of the play instead.

It most often happens when a catcher sets up too close and his mitt clips the bat. The umpire lets the play go on, because the result may be better for the offense. Then the manager chooses the penalty or the play.

On the award, a runner who was forced moves up one base. A runner who was not forced stays. If the batter reaches first and every runner moves up at least one base on the play, the play stands. If the catcher interferes before the pitch is delivered, it is not called. Time is called, and they start over.

Batter's interference is the reverse. Under MLB Rule 6.03(a)(3), a batter who hinders the catcher's play at home, such as by stepping into his throw, is out. Runners go back.

Tips by skill level

Beginner tip

If you feel the mitt hit your bat, keep running out the play. The umpire will sort it out after.

Advanced note

Managers should decide fast. The choice must be made right at the end of the play.

Example

A catcher's mitt clips the bat on a swing, and the batter grounds out. The umpire calls catcher's interference. The batter is awarded first base, and the out is wiped away.

Why it matters

Catcher's interference turns an out into a base. Knowing the rule helps hitters, coaches and catchers react the right way.

Common mistakes

  • Catchers setting up so close their mitt reaches the swing
  • Thinking interference is called before the pitch is thrown
  • Not knowing the manager can take the play instead
