Entering the final week of regular season play, Catholic school girls’ volleyball teams were seeking both league titles and favorable seedings in the CIF-Southern Section playoffs that begin next week.

The weekly Divisions 1 and 2 CIF-SS poll was unchanged with respect to the top four: Redondo Union, Marymount, Mater Dei and Sierra Canyon. Santa Margarita rejoined the top group in 16th; the divisions will be separated at playoff time.

La Salle remained second for the seventh straight week (behind Ontario Christian), and Notre Dame Academy was again eighth in Division 3. St. Anthony held on to fourth in D-4, while Chaminade remained fifth in D-5.

Mary Star dropped from third to fifth, and St. Bonaventure from sixth to seventh, in D-6; Sacred Heart inched up from sixth to fifth in D-7; and Bishop Diego climbed into tenth in D-8. Listed just outside the rankings are Bishop Montgomery (D-1&2); Providence of Burbank (D-6); Ramona Convent, St. Bernard and St. Monica Academy (D-8); and Santa Clara (D-9).

League play ends this week, playoff seedings will be announced Oct. 19, and playoff action begins Oct. 22.
