Other than that, MGK got it.

You shouldn't kill the play at 2B in this scenario because the runner wasn't put out. If she's safe, the ball is still live.

While killing the play would make absolute sense in terms of not having a riot on your hands when you award 3B, that's not how the book is written. So while I agree with your reasoning, I'd have a tough time backing it up with what the book says.
