Your Reaction ???

I guess the first thing I do is wonder how I saw this, when my responsibilities were elsewhere. Or, I guess the first thing I would do is try to turn quick enough to see if R3 and BR touched their bases.

In any case, I'd do nothing until PU said something. What looked to me like a pick up from 70-90 feet away (while concentrating on other things) may not have actually been intentional - PU is 5 feet away.
