Where does the obstruction rule say anything of the sort? It doesn't, it says impedes a runner who is legally running the bases. Running the bases includes all action of a runner, advancing, returning, rounding etc. The runner has every right to round a base and look to see what the defense is doing. It's still obstruction by the defensive player who is standing on the base and making the runner go around them.No, she does not have the right to round the base unimpeded. She has the right to progress to the next base unimpeded. If she is rounding to stop and look, the obstruction before that did NOT prevent her from making it anywhere safely. The momentum needs to be continuous.
