3. If a batted ground ball deflects off the pitcher and another fielder attempts to field it, the call is interference.

4. If a batted ground ball deflects of another fielder, and a second fielder move to field it, the call is obstruction.

5. If a batted ball in the air deflects off any fielder and a second fieder moves to catch it, the call is interference.

So in five situations we have two obstruction calls and three interference calls. Of course, any deliberate action by a runner will over-rule obstruction.

Agree. But the OP is your situation #4, so in NFHS, OBSTRUCTION is the call.
