HIGH SCHOOL BASKETBALL

Santa Ana Mater Dei (30-0) vs. Riverside King (26-2) at Honda Center.

Tonight at 6:30 p.m. FSN Prime Ticket.

Why it matters: Mater Dei, ranked No. 1 in the nation by several publications, is trying to win its 20th Southern Section championship for Coach Gary McKnight. This Division I-AA final figures to come down to whether King’s guards can handle Mater Dei’s exceptional duo of UCLA-bound Tyler Lamb and USC-bound Garry McKnight. And the 6-foot-10 Wear twins, David and Travis, aren’t too bad themselves. King counters with 6-7 Kawhi Leonard, who has turned himself into a player-of-the-year candidate. The winner will be the likely No. 1 seed for next week’s Division I Southern California Regional playoffs.
