Former Southern Cal guard Byron Wesley is transferring to Gonzaga for his senior year of eligibility.
Wesley will be allowed to play immediately because of the NCAA's graduate transfer rule.
Wesley, who led the Trojans with 17.8 points and 6.4 rebounds per game last season, chose Gonzaga over Oklahoma State and Pittsburgh.
"It starts with the winning culture," Wesley told ESPN.com on Sunday. "They've been to the NCAA tournament 16 straight times, and it's an opportunity for me to play in the tournament in my last year."
Gonzaga already has senior guards Kevin Pangos and Gary Bell Jr. It also returns center Przemek Karnowski and adds transfer forward Kyle Wiltjer, freshman point guard Josh Perkins and freshman power forward Domantas Sabonis.
