Considered to be one of the top players in his 2015 class, Zimmerman says that the visit was only planned days before the UCLA game.
"I knew probably like three days before that I would be visiting Arizona," Zimmerman said. "The game was great. I thought Arizona could have played a little bit better, but they did a great job.
"After the game, I went and talked with the coaches and they took me around and introduced me to the players and showed me the campus. I saw all of the new stuff they have and it was a great campus."
In addition, Zimmerman had an opportunity to sit down with Sean Miller and discuss his possible future role as a Wildcat.
"I talked with Sean Miller the most," he said. "They are going to recruit me hard and they told me I would fit in great at Arizona and I am perfect for what they do."
Due to the fact that Zimmerman is so young, he says he is not ready to name any schools as a leader in his recruitment.
"There are not really any leaders right now," he said. "I am just trying to take my time and focus on getting better until it really gets down to making a decision."
As Zimmerman does go on unofficial visits, he has a good idea of what he is looking for.
"I am looking for a good coach and a team that works well together," he said. "Other than that, there are not any other specific things."
In addition to enjoying his visit to Arizona, Bishop Gorman won a state title Friday night.
"It was great and I am happy to be a part of that team," Zimmerman said. "I hope that everybody on that team can go really far."
