Honesty is the best policy?

"but if a ball is hit 365 feet to straight away center then the BU should be out there watching the play"

David,
In a 2-Man System, with BU in the A-Position, the Plate takes all fly balls from 2nd base to the left field stands. Once my partner sees that I'm heading to watch the flight of the ball, he needs to watch the BR. If my partner had turned to watch the ball instead, then you're correct; I would have been following the Batter/Runner.

That wasn't the point of this discussion though. It had to do with an official reversing his call based on the statements of a player versus what the umpire perceived.
