Hill announced on Wednesday morning that he was committing to the Bruins via Twitter.
The three-star had a couple of other Pac-12 offers but figured to see his recruitment soar this spring.
Hill comes from the Ground Zero 7on7 program that UCLA has had great success with in the past.
He is also teammates with one of UCLA's top defensive targets, defensive end Jeremiah Martin, at Cajon.
Scout will have more from Hill.
