Since no throw was made, this is obstruction without an attempted play. You would “award” the runner after all action has ceased the bases to which would nullified the obstruction. In this case, returning to 2nd base. However, had the pitcher thrown the ball, t
his would be obstruction on the SS with an attempted play. As such, you would call “time” and award the runner one base beyond the base last legally required which, in this case, would be 3rd base.
