Can't say much about the UIC....didn't know him; never worked for him at previous tourneys.
I asked one of the "umpire assistants".....individuals that were assisting the umpire crews with water; food, etc....."were everyone evaluated as the practice at Nationals to determine the Sunday crews?"
He stated that each were evaluated on Saturday and the final day crews created from that data.
I know the crew that worked the next game on that Sunday did an excellent job with plenty of hustle; communication to each other; great mechanics; PU had a very consistent strike zone....and as a result, no challenges by the coaches.
