Runner Interference

[valhalla]

High School FED rules
BR on 1st runs when ground ball is hit to 2nd base fielder.
Runner comes so close to fielder that she almost steps on glove and barely clears front of fielder - 1 or 2 inches from my point of view looking directly from 1st to 2nd (spectator). The runner and the ball arriving was nearly simultaneous. The ball went through.
Only one ump working behind plate ruled no contact, no interference! He also said runner has a right to baseline.
Isn't this a case that there can be interference without contact? If yes, would many umps be reluctant to make the interference call?
Thanks.

Does anyone know a good forum for scorekeeping?
