A clash between Arizona powerhouses headlined last weekend's Super 15 West matchups.

No. 11 Liberty (Peoria, AZ) made a statement with a 38-7 win over No. 5 Hamilton (Chandler, AZ) to earn the top spot in Arizona this week, while Santa Margarita (Rancho Santa Margarita, CA) remains at the top of not only the West, but the national rankings.

With the final weeks of the regular season underway, here are USA TODAY Sports' Week 11 West Region Super 15 rankings.

1. Santa Margarita (Rancho Santa Margarita, CA)

Santa Margarita had another statement win over JSerra on Friday, reaffirming its spot as the top team in the West and in the nation. The Eagles have held strong all season against some of the nation's top teams, and they'll finish off the regular season this week against Orange Lutheran.

2. Bishop Gorman (Las Vegas, NV)

Bishop Gorman was idle this week, before facing its final three opponents of the regular season.

3.  Sierra Canyon (Chatsworth, CA)

Sierra Canyon continued its undefeated regular season run with a dominant 63-6 win over Notre Dame (Sherman Oaks). Demarco Hernandez had quite the performance this week, throwing for 182 yards and two touchdowns while also adding 116 yards and two touchdowns on the ground.

4. St. John Bosco (Bellflower, CA)

St. John Bosco bounced back from a loss to Santa Margarita with a dominant victory over Servite. Senior Maliq Allen starred this week, with 136 yards and four touchdowns on the ground. The Braves will have to fight to finish their regular season on a high note this week against Mater Dei.

5. De La Salle (Concord, CA)

De La Salle added another win to its undefeated run and handed San Ramon Valley its first loss of the season on Friday. Senior Judah Pape found the end zone twice – his first multi-touchdown game of the season. The Spartans have two more games before closing out the regular season.

6. Mater Dei (Santa Ana, CA)

Mater Dei has won three-straight games since suffering back-to-back losses to Bishop Gorman and Santa Margarita earlier this season – this week over Orange Lutheran. The Monarchs have a big one this Friday against St. John Bosco to close out their regular season.

7. Liberty (Peoria, AZ)

Liberty had the chance to prove that it is the best team in Arizona on Friday, and it did exactly that, taking down Hamilton 38-7 and handing the Huskies their first loss of the season. Senior Jayden Sanchez had his third-straight two-touchdown game and will look to continue that streak in Liberty's final two regular season games.

8. Folsom (CA)

Folsom had a nail-biter against Del Oro on Friday, but squeezed past with a 42-41 win. The Golden Eagles scored in the final minute of the game, but missed the extra point that could have sent the game to overtime. The Bulldogs are idle this week before their final regular season matchup against Jesuit.

9. Basha (Chandler, AZ)

Since back-to-back losses at the beginning of the season, Basha has won five-straight games, including this week's victory over Brophy College Prep. The team's past three games have been the highest scoring games all season, and the Bears will look to continue that offensive fire in their final two games.

10. Chandler (AZ)

Chandler followed up with its most impressive win of the season over Centennial with a massive 79-0 shutout over Valley Vista. Will Mencel threw a season-high five touchdowns, and the Wolves have now won seven-straight games since its season-opening loss to Basha.

11. Hamilton (Chandler, AZ)

Hamilton took its first loss of the season to Liberty, a game in which the Huskies were held to just one touchdown. They'll have a chance to bounce back this Friday against Cactus Canyon before facing Chandler in its final regular season contest.

12. Mountain Ridge (Herriman, UT)

Mountain Ridge piled on another win last week with a 21-13 victory over Westlake, although it was the Sentinels lowest-scoring game of the season. Xander Thayer followed his three-touchdown performance last week with another two touchdowns. Mountain Ridge will close out its season this week against Cedar Valley.

13. Centennial (Corona, CA)

Centennial managed to take down Chaparral without ALL-USA wide receiver Quentin Hale, who suffered a shoulder injury against Norco. After being tied up at halftime, the Huskies pulled away with a 41-27 victory. Centennial has one final regular season game against Murrieta Mesa on Thursday.

14. Puyallup (WA)

Puyallup grabbed its second shutout of the season, this time a 44-0 win over Emerald Ridge. Senior Noah Smith threw for 239 yards and four touchdowns, with two of those going to freshman Sosaia Sekona. The Vikings will play in the Crossover Championship game against Graham-Kapowsin.

15. Centennial (Peoria, AZ)

Centennial bounced back from a loss to Chandler with a shutout over Mountain Ridge. Titus Hill completed 14-of-18 passes with four touchdowns while Luke Franklin dominated on the other side of the ball with five tackles, 2.5 sacks and an interception. The Coyotes will face Boulder Creek this week before closing out the regular season against Liberty.
