Runner on 2nd base with two outs. Batter hits a line drive base hit to the right fielder who is playing shallow. Right fielder picks up ball and throws to first baseman covering and the runner is out on the legal force play out. However as the ball is being field by the right fielder the runner at second is rounding third and the plate umpire (2 man mechanics) sees and calls obstruction just before the runner is called out at first. Does the run score now on this play as the runner at third was obstructed just passed the third base bag when then the runner going to first is called out?
