Interfence?

[Colt2Cat]

Question on a call.

R1,R2,R3, No outs. Ground ball hit to F4. As R1 proceeds to second in the normal basepath, unintentionally and without contact passes directly in front of F4 making the play and in my opinion, causes F4 to bobble the ball and no play is made. I call interfence immediately, R1 Out, R2 back to second, R3 back to third, BR safe at first. First question; was this the correct call. Second question; argument was made that the baserunner has the right to the basepath but I have always thought that the fielder has right of way anywhere on the field. Which is correct?
