Temecula Valley was the only top-seeded CIF Southern Section Division 1 playoff team not to find victory in Tuesday's opening round of pool play. No. 11 Huntington Beach beat the No. 8-seeded Golden Bears 11-0.

Star Jared Gringlinger allowed just one hit in six innings of work. Ely Mason and Dane Cunningham each hit homers in the convincing win.

The rest of the top-seeded teams — which all hosted — won their matchups, but it didn't come easy.

St. John Bosco went 11 innings with Cypress and prevailed 2-1 thanks to Moises Razo's walk-off RBI at home. The Braves are the defending D1 champs.
