Runner Interference (OBR)

Runner interference gets its own explanation because it can occur in a variety of ways. Generally, runner interference is clear and the outcomes are obvious. However, there are some sencarios that requrie more nuance.

The first type of runner interference to consider is when a runner is hit by a batted ball in fair territory before the ball passes a fielder (and no other fielder had a chance to field it). In this case, the runner is out, the ball is dead, and other runners return to their bases (Rule 5.09(b)(7)). This rule applies even if the runner is standing on a base when hit (i.e., the base is not a safe haven in this situation).

One seemingly trivial detail of this rule is when a batted ball hits two runners (unlikely but possible). In this case, the first runner is out and the ball is immediatly dead, thus the second runner is not out but is requried to return to the last legally occupied base. This same priciple applies to the next type of runner interference.

The second type of runner interference to consider is when a runner phsically hinders a fielder attempting to field a batted ball. This could include unintentional or intentional contact (the consequences vary). See Rule 6.01(a)(6) and Rule 5.09(b)(3).

The runner can also interfere on a throw ball, but it is only interference if the interference is intentional. Just being hit by a thrown ball does not consitute interference itself. See Rule 5.09(b)(3).

A more complicated senario of interference occurs when the runner is hit by an infield fly. If the runner is hit by an infield fly ball while on his/her base, the ball is dead, the batter is out on infield fly, and the runner is not dead. See Rule 5.09(b)(7). This is a rare case of a runner being hit by a live ball and not being called out. However, if the runner is off the base when hit by the infield fly, the he/she is out for interference, the batter is out on infield fly, and the ball is dead.

One important caveat to runner interference is that a runner is not out for interfering with a fielder attempting to make a play on the ball if the runner is on the base. This is distinct from the runner being hit by a batted ball while on the base, which is interference (dead ball, runner out). See Rule 6.01(a) Penalty for Interference Comment.

Examples

  1. A runner intentionally collides with a fielder attempting to field a batted ball.
  2. A runner is hit by a live ball (on or off a base, and the ball is not an infield fly).

Frequently Asked Questions

  • Is all contact interference?

    No. Contact is only interference if it hinders or impedes a fielder making a play.

  • Can a coach commit interference?

    Yes. A base coach who physically assists a runner or obstructs a fielder can be called for interference.
