It is a legal slide. So the slide itself may not be interference under 8-6-13.

But that is only part of the question, I would think. Did an already-retired runner interfere with the defensive player's opportunity to make a play on another runner 8-6-18? Once the slide part is done, the pop-up is a separate and intentional action that needs to be considered. We say the runner is expected to try to be safe, and isn't required to give up; but the pop-up has nothing to do with trying to get to the base safely. The pop-up is to be able to continue to a NEXT base on an overthrow, OR just to disconcert (or interfere with) the defensive player.

Not opening the huge can where anything that the runner does is interference. And we would expect this one to be you would know it when you see it. But if the legal slide then results in a pop-up that interferes with the throw when there remains an opportunity for a play ........
