LA South: Five things from the weekend

1. There won't be any movement in the L.A. South top 10 this week, as eight teams emerged victorious. The other two -- Dorsey and Bonita -- were idle.

2. Don't mistake No. 5 Gardena Serra for a soft-playing team just because it likes to go vertical, put up points and run a spread offense. The Cavaliers don't shy away from contact. Serra manhandled Narbonne in the trenches and Gauchos quarterback Troy Williams paid for it, limping off the field on various occasions Friday night. When you're expecting the pass, tailback Shaquille Richard is the ideal change-of-pace compliment to Conner Preston and his wealth of options.

3. It's clear now: Two-sport star Rio Ruiz has a firm grasp on the Bishop Amat offense. The junior threw for 245 yards -- all in the first half -- to carry the Lancers (5-0) to a 53-6 win at Los Angeles Cathedral. Ruiz is committed to play baseball at USC, but will he have the urge to play at the Coliseum too?

4. How about the 41-0 trouncing Diamond Ranch put on "crosstown rival" Diamond Bar in the teams' first ever meeting? Diamond Ranch, which opened just 13 years ago and sits on the border of Pomona and Diamond Bar, is coming off back-to-back division title game appearances. The Panthers began the season 0-3 -- including a 56-0 loss at Santa Margarita in the opener -- but have bounced back with two necessary wins. They're a dangerous sleeper in the Hacienda League.

5. Palisades Charter took the crown at the Weisenburger Invitational at Elysian Park on Saturday. Junior Grant Stromberg won the boys three-mile with a time of 15:41:00, while sophomore Jacklyn Bamberger ran a 19:02:00 to claim the girls three-mile.
