When do you call interference?

[Roger Greene]

Intresting play that I observed in NC NFHS 2A simi finals in 2000.

R1 attempt to steal on pitch. H&R on. Batter hits ball just right of second base.(F2 would be pleased to throw ball so well.) F6, covering on steal, and less than a foot to the right of 2nd is taken out by R1 executing legal slide as she attempts to field batted ball.

Inteference with F6 attempting to field batted ball or no call?

Ruling on field was no call, R1 and BR safe. I posed the play on one of the softball boards before, and the consensus was no call.
