BOYS’ BASKETBALL

* Nike Extravaganza III, Saturday, UC Irvine: Mater Dei hosts this annual six-game event at the Bren Center, but the unranked Monarchs are far from the top draw. Marquee teams include the nation’s third-ranked team, Elizabeth (N.J.) St. Patrick, which will be a heavy favorite at 5 p.m. when it takes on Mater Dei. Seventh-ranked Mouth of Wilson (Va.) Oak Hill Academy began the week with a 17-game winning streak. It plays No. 15 Compton Dominguez, led by forward Tayshaun Prince, at 7 p.m. Orange County’s top-ranked team, Santa Margarita, faces No. 6 Servite at 1 p.m. The county’s second-ranked team, Ocean View, opens the day at 11:30 a.m. against Etiwanda.
