Basically, yes. You would always error on the side of awarding him third if there was any way that he could have been safe. But he would still be out if it was obvious he could not have made it. But he has to go. If the umpire calls obstruction and he goes back to second, he stays at second.i think illini is saying that, in that example, if the runner tried to advance to third and was throw out, the umpire would use his judgment to determine if he would have been safe at third if he were not tangled up with the shortstop. if the ump thought he would've been safe at third, he calls obstruction and gives him third base. if he thought he'd have been out anyway, he calls him out.
