"Larry feel in love with it," Lewis' AAU coach Jeff Delvega said. "We did all the pros and cons the last couple of days and Larry wanted to get it out of the way."
"We've had multiple conversations with coach O'Neill and Bob Cantu," the Arizona Magic coach added. "They've been out to see Larry quite a bit this year at the high school. Every time they came to see him they loved him more and more."
Lewis, who also had interest from Oregon State and Arizona State, took a trip to USC a few weeks ago and that helped seal the deal.
"Larry did an unofficial to USC with his mom and just loved it," Delvega said. "He loved the campus. He loved the coaches and just thought it was a great place to be and a place he needed to go."
A standout at Phoenix (Ariz.) Arcadia, Lewis, who won't turn 16 until September, averaged a team high 22.4 points, 7.7 rebounds and 3.2 assists for the Titans, who finished 19-9 on the year.
"He's got tremendous upside," Delvega said. "Obviously he can put the ball in the hole. He's incredibly athletic and can shoot the ball extremely well. He needs to work on the one stuff, which we'll work on over the next couple of years."
Lewis is USC's first verbal commitment in the 2012 class. They also have a trio of early verbals from 2011 prospects. Byron Wesley and Gelaun Wheelwright are both on board, as is JUCO standout DeWayne Dedmon.
