ASA - Obstruction or good play

[SamNVa]

Does possession require control?

Batter hitd a ball to the outfield, runner is trying to score from 2nd, Catcher is set up in front of the plate waiting for the throw. Throw skips as it comes in causing F2 to mishandle it and the ball ends up trapped against her side in the crook of her elbow. Catcher knwos the runner is approaching, so she plops down in front of the plate; runner slides in and is stopped short of the plate, the catcher finally manages to get rhe ball in her hand and tags the runner. Now, speaking ASa what's the call, obstruction or out?
