Bellevue (Wash.) four-star defensive tackle Marcus Griffin waited until Signing Day but made his choice on Wednesday.
Griffin announced on Wednesday morning that he was signing with Arizona.
"I have officially committed to the University of Arizona," said Griffin. "Bear Down Baby!"
The Semper Fidelis All-American chose the Wildcats over a final group that included California, Mississippi State and Washington State.
"I felt it was the best fit for me," said Griffin. "This decision wasn't really about football as much as academics. I wanted to be able to continue sign language while also having a degree from a top 10 business school."
As a prep, Griffin never lost a game, helping the Wolverines win three state titles and going 42-0 as a two-way lineman.
Griffin is the fourth Semper Fidelis All-American that the Wildcats inked in the 2014 class.
