No. 2 Mater Dei (Santa Ana, Calif.) at Centennial (Peoria, Ariz.)
When: 9/6, 10 p.m. ET
Analysis: Centennial stands among the best teams in the country, winning the last two Arizona championships and knocking off out-of-state powerhouses Bishop Gorman (Las Vegas) and St. Thomas Aquinas (Fort Lauderdale, Florida) in the process. But while the Coyotes have been winning titles in Arizona, Mater Dei has won two straight National Championships. If Centennial is indeed the giant-slayer, can they take down this Goliath?
