Jurisdiction of call

[kchamp]

Sit:
I'm UIC, and the batter just swung at the third strike and took 4 or 5 steps to the dugout when she realizes that the pitch was not caught by F2 an then bolts for 1st. Now the BU chimes in calling the BR out for a) abandonment (wrong) or b) not running in the lane (again wrong).

At this point, what does the UIC do?
Issues I'm thinking about:
a. It's my call
b. Do no critisize or reverse another umpires call
c. Let offensive coach initiate appeal

Thanks
