Interference Ruling

Question
Runner on third runs into third baseman trying to catch a foul ball. Who should be called out runner or batter and is it a dead ball situation?

Answer
Barry,

The player committing the interference is always the one called out unless they are already out or have scored.  If they are already out or have scored, the lead runner is out.  Also interference is always a dead ball.

So in your situation, dead ball runner on third out.
