The Mira Costa boys volleyball team is the No. 1 seed in Division I of the CIF Southern California Regional playoffs that, for the first time, will be followed by the CIF State championships.

Usually, the regional playoffs mark the end of the boys volleyball season, but this year the regional winners from Northern and Southern California will meet in the first boys CIF State finals on May 31 at Fresno City College.

The Mustangs won the CIF Southern Section Division 1 championship Friday night by beating Huntington Beach. They will host No. 8 Beckman in the first round today at 6 p.m. Mira Costa defeated Beckman in three sets in CIF-SS pool play April 30. If the Mustangs win, they would face No. 4 Carlsbad or No. 5 Newport Harbor in the regional semifinal on Thursday.

The regional final, set for Saturday, could be a rematch of the CIF-SS final, assuming Mira Costa and No. 2 Huntington Beach win their first two matches. The Mustangs, as the top seed, would host the final.

Redondo is the No. 7 seed and will open at Huntington Beach today. The Oilers swept the Sea Hawks in pool play May 6.

In Division IV, CAMS, the CIF-SS Division 9 champion, is the eighth seed and will face top-seed Mater Dei Catholic of San Diego today.
