Running back Malik Roberson and Serra High take on Huntington Beach Edison in a Division II regional game Saturday night. Lawrence K. Ho / Los Angeles Times Times staff reports December 7, 2012, 5:40 p.m. Corona Centennial (13-1) vs. Harbor City Narbonne (14-0) at Cerritos College, 7:30 p.m. (TWC SportsNet): After shutting out a high-powered Crenshaw offense last week, Narbonne's highly regarded defense faces its biggest test yet against a no-huddle, fast-paced offense that has lots of weapons. Centennial's powerful offensive line had better be able to block lineman Paulo Lepua and linebacker Keishawn Bierria. Narbonne quarterback Troy Williams will need to make the right decisions on whether to run or pass against an aggressive Centennial defense. The pick: Narbonne Gardena Serra (12-2) vs. Huntington Beach Edison (13-1) at Orange Coast College, 7:30 p.m. (TWC 700 HD): Serra has a speed advantage, but Edison is used to playing in big games and won't be intimidated. The Cavaliers had zero turnovers last week against Chaminade, and a repeat performance will make them tough to beat. Adoree' Jackson has been taking charge on offense and defense for Serra. Edison quarterback Aleksander Torgersen has passed for 2,242 yards and 17 touchdowns. The pick: Serra. San Diego Madison (12-1) at Monrovia (12-2), 7:30 p.m.: Madison won the San Diego Division IV championship behind Arizona-bound running back Pierre Cormier, who rushed for 157 yards and scored three touchdowns. Receiver Lee Walker is also committed to Arizona. Monrovia has won three consecutive Mid-Valley championships behind linebackers George Frazier and Brett Walsh. The pick: Madison.
