Is this obstruction?

Batter hits a chopper to the short stop who gloves it and throws toward first the throw is a little inside and the first baseman reaches across first base to glove it. She hits it with her glove and deflects it toward the fence. As she reaches for the ball the runner is coming in and gets clotheslined by the fielders glove arm going down hard.
Obviously, it's mostly HTBT, but what can you tell me for calling something like this? The umpires on the field didn't call it (NCAA game) but I'm wondering if that's because fielders get more leeway there. My thought is that since the fielder didn't have any possession of the ball, she has no out for this in ASA or NFHS, yes?
