Allow me to add a slightly different viewpoint to this situation. OBR (Yeah - I know, OBR ain't softball
) has an interp that basically says if the deflected ball is within reach of the fielder, you are still gonna protect him. More than a reach and he's a likely candidate for obstruction.
If the fielder pivots into the basepath reaching for the ball - it could still be INT. Otherwise - possibly OBS. HTBT.
