Lookback Rule at 2nd Base

[dan_renninger]

I had this question asked to me by a coach concerning the new FED lookback rule and wanted to get some feedback from the distinguished brethern. Here's the play;

No outs. R1 is on 2nd base. B2 is at the plate with a 3-2 count. As the pitch is released R1 takes a strong secondary lead from 2nd, but the pitch is a ball. B2 heads down to 1st, takes an aggressive turn at the bag, comes off the bag about 10 feet, comes to a stop, and then heads back to 1st. R1 is still off 2nd watching the action. When does she have to get back to 2nd?

Here is the answer that I want to give to the coach. R1 is not influenced by the lookback rule - only B2 going to 1st base on the walk. R1 needs to return to 2nd once the pitcher has the ball in the 16 ft circle. Of course if the pitcher makes a play on B2 then all bets are off.

Do i have a clue? Let me know.
