I would have said that the PU's would be responsible for F1's step and after that be responsible for the ball on a pickoff at first base. What set of mechanics are you using where the PU on pickoffs watches R2?[/quote]
If we were in this position as players, I as R2 would be off on F1's move to 1st. Being in a secondary and my speed, I would now be on 3rd (I was faster in my youth). This was a standard move on a "throw behind".
Now I understand as an umpire you holding to CCA mechanics but now we have a situation where the CCA does not cover the problem. You know that F3 is going to try to nail me going to 3rd and anything under NCAA is probably going to end up as an overthrow. So while the BU is covering the pickoff at 1st, who is going to handle the action at 3rd? Your BU is not going to be able to cover this.
Of course, if you are working Summer leagues or sub-varsity, R2 problable will have bought a ticket to the action and will never have left 2nd base. So then your job will be easy. Come to think of it, never mind the above scenario becaues no one plays ball like we used to, anymore. I hardly see any agressive playing anymore so my actions as a former professional player problably are only avilable on 16mm instant replay!

Good arguing with you again LDUB (aka LubDub)!
