Obstruction

[Dakota]

That would be up to you as the umpire. The obstruction is in effect until the runner reaches the base to which you have decided to protect him/her (or THEM as Dakota would prefer )

Actually, I would prefer, "until the runner reaches one of the several bases to which the umpire may or may not have judged all and sundry runners would have reached..."
