Defensive Obstruction? NFHS

[Blueplate]

Runners on 1st and 2nd. Runners are going on the pitch. Batter hits grounder to SS, she quickly fields the ball and turns to throw to 3rd. In doing, so after the throw, she stumbles and falls into the runner coming from 2nd who has tried to go around her. The runner is knocked down. The throw is caught by the 3rd baseman...for the force out.

Could defensive obstruction be called since she no longer had the ball and clearly hinder the runner...before the ball was caught.
