Clearly outside....to what degree we will not know as the camera that showed the zone was on an angle as well...without an overhead shot we will never know.
Despite that, the replay showed what I felt was the umpire out of position on the call....he seemed to be angled in rather than in the working slot.
The NCAA hates to be embarrased, and the replay and the telestrator analysis was pretty convicting. That being said, I know a number of umpires who have been chosen for NCAA championships and I can say that without a doubt they are the best of the best.........does that keep mistakes from happening?........no...
Just to show you that the umpire knew he missed it as well, you can tell by the amount of "discussion" he allowed about his Ball/Strike calls by the RICE Manager Graham.
