Four Catholic high school basketball teams (three boys’ and one girls’) have reached the semifinals of the CIF Southern California Regional Basketball Tournament, after victories March 9 and 10.

Three of those four teams who will do battle March 13 will play teams they’ve faced earlier in the season:

  • In the Boys’ Open Division, third-seeded Bishop Montgomery (28-1) gets a rematch with second-seeded Sierra Canyon (24-4), 7 p.m. at Calabasas HS. The Knights of Torrance beat the Trailblazers of Chatsworth 65-62 in Cerritos on Jan. 5, but Sierra Canyon turned the tables with a double-overtime 77-74 win in the CIF-SS Open Division semifinals on Feb. 24.
  • In the Boys’ Division I bracket, top-seeded St. John Bosco (24-7) hosts fourth-seeded Rancho Christian (29-4) in Bellflower, 7 p.m. The Braves beat Rancho Christian 73-66 on Dec. 28 in the Damien Tournament, rallying from a 10-point halftime deficit.
  • In the Girls’ Division I playoffs, second-seeded Serra of Gardena (22-8) plays Sierra Canyon (23-8), which defeated Serra 57-52 on Dec. 9 in the Sierra Canyon Invitational Tournament in Chatsworth.

The other March 13 matchup, in Boys’ Division III, finds tenth-seeded Bishop Amat (28-6) playing Murrieta Mesa (26-9) in La Puente.

Winners of the March 13 semifinals in all divisions advance to the March 17 finals. Those victors will play for state championships March 23 or 24 in Sacramento against winners of the Northern California Regionals.
