OBS? INT? Or What?

[DaveASA/FED]

Origianlly I agreed with bluefoot, I had all situations as OBS, except for maybe C ac INT if she tried to make the ball move away from her not just protect herself (HTBT). But as I read the ASA POE, it says the fielder has the right to make a play without being interfered with. It did not mention on a batted ball, it said make a play. So now I am SO confused, on one hand you have OBS as the fielder didn't have possesion, on the other you have INT as they were making a play (well maybe). I guess we get into more definations, what is making a play? Is picking up the ball making a play? Or is applying a tag, or touching a base, and fielding a batted ball what is takes to be making a play? I'm very interested to hear what others think, this has really got me rethinking what I thought I understood about OBS!!
