Three boys’ and two girls’ Catholic high school basketball teams will play this weekend for CIF-Southern Section championships, topped by the Open Division boys’ title game Friday night featuring Mater Dei against Sierra Canyon.

Trinity League champ Mater Dei hasn’t lost since Jan. 15, at the Spalding Hoopball Classic in Springfield, Mass., to Montverde Academy of Florida, and has won 11 games straight. Sierra Canyon, rated 19th nationally by Maxpreps, features Cassius Stanley, the No. 2-rated shooting guard in the U.S., and the sons of four former NBA players including Scotty Pippen (son of Chicago Bulls’ Hall-of-Famer Scottie).

A look at each game, in chronological order:

—March 2, 6 p.m., Boys’ D-3A: Bishop Amat (26-5) vs. Notre Dame/Riverside (27-3), at Azusa Pacific University. The third-ranked Lancers of La Puente — whose lone CIF-SS title came in 2002 — edged Buena, 54-53, to gain the final against the No. 1-ranked Titans, winners of 20 straight and unbeaten (14-0) in the Ambassador League. Bishop Amat has won 18 of its last 20, losing only to Camino Real League champ St. Anthony.

—March 2, 8:30 p.m., Boys’ Open: Mater Dei (22-6) vs. Sierra Canyon (23-3), at Cal State Long Beach.
