1st and 3rd rundown play

[illiniwek8]

Ok, thanks for the input....so the thing here is where the runner is at the time the second baseman receives the ball and begins to make a play on him....wherever the runner is at this time.....he has to run in a line either to second or back to first.......if he deviates more than 3 feet to either side.....he is out? Thanks for the insight.....this clears things up.
