Corona del Mar High is the No. 2 seed in Division I-A and Sage Hill is the No. 4 seed in Division IV-AA to highlight area teams competing in the CIF Southern Section girls' volleyball playoffs.
Newport Harbor (Division I-AA) and Estancia (I-A) are also taking part in the postseason, which begins Tuesday for all four local teams.
The Sea Kings (27-3), the Pacific Coast League champions at 10-0, are at home for their 7 p.m. first-round match. They will take on the winner of Monday's wild-card contest between Brea Olinda (13-13) and Saddleback (10-10).
Sage Hill (13-3), which shared the Academy League title with St. Margaret's but lost a tiebreaker and is the league's No. 2 representative, plays host to Chino (11-3), the fourth-place team from the Mt. Baldy League, in a 7 p.m. first-round match.
Newport Harbor (21-8), the Sunset League's third-place entry, is on the road to battle Westlake (21-7), the runner-up from the Marmonte League, in a 7 p.m. first-round battle.
Estancia (7-12), the third-place team from the Orange Coast League, visits No. 4-seeded Vista Murrieta (28-7), the Southwestern League champion, at 7 p.m. Tuesday.
CdM, which has won eight of its last nine, features a balanced attack. First-year coach Marissa Booker's leading hitters are 6-foot-2 freshman Hayley Hodson (241 kills), 6-3 junior Grace Kennedy (237) and 6-2 senior Britton Taylor (200).
Junior setter Kelsey Humphreys has 595 assists, while senior libero Marry McKennon leads the team in digs (331) and aces (42).
CdM, which lost to I-A top-seed Marymount at the Santa Barbara Tournament of champions on Oct. 29, could meet No. 3-seeded Laguna Beach in the semifinals. The division finals are scheduled Nov. 18 and 19 at Cypress College.
Newport Harbor, ranked No. 5 in the final Division I-AA poll, is led by USC-bound setter and outside hitter Cinammon Sary.
Coach Dan Glenn's Sailors also rely heavily upon senior libero Tatum Norton and senior middle blocker-outside hitter Kasey Thompson.
"It's the playoffs and anything can happen," Glenn said. "I don't know a lot about [Westlake]. We're the fifth seed, but the equalizer is we're on the road. I think we're in a pretty good spot. As a third-place team, you can't expect too much. But we've competed against the best."
If it can win two matches, Newport Harbor could face No. 4-seeded Mira Costa in the quarterfinals.
