Do you agree with this non-call?

I'm not the most experienced umpire on this board, but I'll give you my thoughts on your play, if for no other reason than to see what kind of feedback it gets.
From your description of the play, I also have a no call. Interference is a judgement call made by an umpire because the umpire judged the runner to have interfered with a fielder, not because the fielder judged that they couldn't get to the ball (because of the runner). When there is no contact between the two players, we have to look at other factors to determine interference. This may not be correct, but I think I would look at just how much effort the fielder was making to get to the ball.
