I missed the following question on a test:

With a runner on third (R3) a batter hits a ball that drifts over foul territory. The third baseman is accidentally prevented by the runner R3 from catching the ball.



What's the call?

Answer was that the batter is out. I'm struggling to wrap my brain around that answer.

Does the "accidental" aspect play into the ruling at all?

Does fair/foul have an impact on who is out?

Tell me what questions I'm not asking myself.
