Ball's father -- Lavar -- confirmed the news to Scout.com.
"Yes he just made a commitment to UCLA," the elder Ball said. "UCLA is where he always wanted to play and the style they play fits his game."
Connecticut, Syracuse, Washington, USC and San Diego State were among the schools aggressively pursuing the Chino Hills (Calif.) High standout. In the end, Ball wanted to play for the school he grew up following.
"Everything is more comfortable for him right here and this is the best program on the west coast," Ball said.
"He's followed them growing up and most of the guards coming out of there are doing good for themselves and making a good living," he explained.
UCLA assistant coach David Grace took the lead on the Ball recruitment.
Ball, a 6-foot-5 point guard, is a tremendous passer with impressive vision. While his passing is certainly notable, he also has a good-looking jump shot, with range that extends well past the three-point line.
A four star-recruit, Ball is currently ranked No. 21 overall in the 2016 class.
