OBS & overslide

[Zepp]

Need some input on this sitch. Be gentle, since this is my first post. LOL
Please use ASA references.
Sitch: Runner on 2nd. Batter safely hits to left field. Runner on 2nd is obstructed by shortstop on her way to 3rd. Left fielder comes up firing to 3rd and there is a close play. Runner slides, touches bag & beats the tag but her slide takes her past the bag and she loses contact with bag. Runner is re-tagged while off the bag.
What is the call?
Some of my brothers & sisters in blue say the runner is out since she acquired the base (3rd) she would have been awarded and went beyond. The others say they would keep her on 3rd (due to the obstruction) since the runner did not make an "attempt to advance" past the protected base (3rd)
