If the runner makes any effort to advance after that initial block and is blocked again before possession, then you would have obstruction.

Or, if the catcher lays on hers and pins her while retrieving the ball (wasn't there a similar postseason MLB play by Red Sox F5 a few years back??), that would also be obstruction.

Thanks!
