L.A. South: The Top 10

Long Beach Poly fell out of the region's top spot for the first time this season following its second-round loss to Santa Margarita. Last week's second- and third-ranked teams -- St. John Bosco and Charter Oak, respectively -- also stumbled. Now, three of the region's top four squads come from the City Section. Marine League champion and top-seeded San Pedro is the only remaining undefeated team in the south Los Angeles County top 10 rankings heading into the third round of the playoffs:

1. (4) San Pedro (12-0)

The top-seeded Pirates eliminated the two-time defending City Section Division I champs Friday, securing another matchup with fifth-seeded Carson. The Marine League champs defeated the Colts 21-0 on Oct. 28. Last week: Beat Crenshaw, 31-7. Next: semifinals vs. Carson, Friday.

2. (1) Long Beach Poly (10-2)*

The lack of consistency from the quarterback positions was a season-long concern for coach Raul Lara. That turned into a nightmare Friday when the Jackrabbits were intercepted five times. The good news: Gerard Wicks returns next season. Last week: Lost to Santa Margarita, 49-16.

3. (5) Narbonne (9-3)

Junior quarterback Troy Williams had six total touchdowns, and the emerging Tray Boone had two more to propel the Gauchos to their third straight 50-point performance. They now face perhaps the city's top defense. Last week: Beat West Adams, 59-20. Next: semifinals vs. Dorsey, Friday.

4. (6) Dorsey (11-1)

The fast and talented Dons defense had six takeaways Friday, and USC-bound receiver Jaydon Mickens had four total touchdowns to go along with six receptions and 82 yards. Last week: Beat Birmingham, 45-13. Next: semifinals at Narbonne, Friday.

5. (2) St. John Bosco (8-4)*

Bosco twice cut its deficit to four on Friday but the defense couldn't come up with stops. Still, the Braves made their first playoff appearance since 2006, so they've got nothing to hang their heads about. Last week: Lost to San Clemente, 42-24.

6. (3) Charter Oak (10-2)*

Travis Santiago and Kurt Scoby did all they could to keep the Chargers in the playoffs, combining for 411 total yards Friday. But the defense was overwhelmed all night, unable to contain any facet of Upland's dynamic attack. Last week: Lost to Upland, 51-13.

7. (7) Loyola (8-3)*

8. (NR) Santa Monica (11-1)

The Vikings make their first appearance in the rankings following their victory against previously undefeated Ventura. Kori Garcia rushed for 158 yards, Christian Salem passed for 202 yards and three touchdowns Friday. Last week: Beat Ventura, 29-24. Next: semifinals at Culver City, Friday.

9. (10) West Covina (11-1)

Don't mind the top-seeded Bulldogs -- they're just doing what they do. Coach Mike Maggiore's bunch keeps putting up crooked numbers behind the running of tailback Jimmy Frazier. Last week: Beat Pasadena, 55-12. Next: semifinals at La Mirada, Friday.

10. (NR) Culver City (9-3)

First, the surprising upset of top-seeded Gardena Serra. Then, a blowout in the second round. Now, the Centaurs get a chance to avenge this season's three-point loss to Ocean League champion Santa Monica. Last week: Beat Righetti, 51-28. Next: semifinals vs. Santa Monica, Friday.

Dropped out: Gardena Serra (8), Lakewood (9)

Ten more, in alphabetic order: Arcadia (9-3)*, Carson (7-5), Covina (11-1), Gardena Serra (8-3)*, Lakewood (7-4)*, La Serna (9-3), Monrovia (9-3), Muir (8-4), San Dimas (10-2), South East (11-1).
