inteference by batter or not?

[SamNVa]

I would like to add that FED rule 8.1.1b says that the batter becomes a runner when charged with a third strike, with a note that if the third strike is caught or 1st base is occupied with less than 2 outs, the "runner" is immediately out.

So in FED, this player does have the status of a retired runner, for what it's worth.
