In baseball, if a runner interferes with a double play, the specific outcome and consequences depend on the circumstances and intent of the interference. Here are some possible scenarios and their corresponding outcomes:


Intentional Interference: If a runner intentionally interferes with a fielder's attempt to complete a double play, the runner may be called out for interference. The batter-runner would also be called out, and any other runners on base would be required to return to their previous bases. Additionally, the umpire has the discretion to eject the interfering runner from the game.


Unintentional Interference: If the interference is deemed unintentional or accidental, the umpire may rule it as incidental contact. In such cases, the play will continue without any penalties or ejections. The umpire has the authority to judge the intent and impact of the interference.


Interference Prevents Double Play: If the interference prevents a double play from being completed, the umpire may call the runner who interfered out and the batter-runner out. Other baserunners will generally be allowed to advance only if forced to do so. The umpire may also return baserunners to their previous bases depending on the circumstances.


It's important to note that baseball rules can be interpreted differently by umpires, and the specific outcome may vary based on their judgment. The umpire's decision regarding interference is final and cannot be overturned through instant replay review, except in cases involving spectator interference.


If you encounter a situation where a runner interferes with a double play, the best course of action is to consult the official rules of the specific league or organization you are playing under for accurate and up-to-date information regarding interference and its consequences.
