Running outside the base path

[booker227]

Did the defensive player have possession of the ball at the time of the runners' decision to step outside of the line? Was the line established or was it a loose ball situation?
I believe that if the ball was loose, then the runner has the right to avoid a possible collision. IF the ball was possessed buy the fielder then, in my mind, the runner tried to escape teh tag by running outside the line. A judgement call....surely..have fun with that one.......
