CWS FL-AZ plate umpire

[Bandit]

The 3rd base umpire was rotated over due to runner on first. This umpire would have had the best view. NCAA mechanics want the plate umpire to go to the first base umpire.
Yes, I know they all got together. All for show.
But you can see by the involvement of the first base umpire in the actions that took place after the request for more information by Drumm that the rotated umpire had little involvement in any substiquent decision.
