Again, the way the USSSA clarification is worded is absolutely contrary to what the rule actually says. And for that matter, goes completely opposite what the USSSA case book says. The following is from the 2016 case book on obstruction.
By the wording of the clarification, the instant the throw drew the catcher into the base path it should have been ruled obstruction. But, as you can see from the case play it is not. I dont know how many times it has to be said, for all rule sets in order to be obstruction both criteria must be met. The defender not have possession of the ball, and impede or hinder the runner. Without both being met, it is nothing.
SITUATION D: A throw from F9 draws F2 into the base path of R1. The ball and R1 arive simultaneously
causing contact between F2 and R1. F2 drops the ball and R1 scores. The contact is not intentional or
flagrant.
RULING: There is no obstruction or interference. This is viewed simply as a collision. The run counts.
