As expected, J.Serra (Division 4) and Crespi (Division 6) earned the No. 1 seeds in their respective divisions for the CIF-Southern Section boys’ water polo playoffs that begin Nov. 5.

In all, nine Catholic school teams received playoff berths, including three in Division 1: Loyola (third), Santa Margarita (fifth) and Mater Dei (eighth). Seedings are based on the final regular season polls issued Nov. 2.

Other seeded teams include St. Francis, second in D-5, and Notre Dame of Sherman Oaks, fifth in D-3. Damien (D-2) and Cathedral (D-5) are unseeded, though Cathedral won the D-7 championship in 2018.

D-3: Notre Dame/SO (14-7) at Cerritos (7-17).
