CdM and Newport Harbor open the first round at home. The second-seeded Sea Kings (20-8) play Mission Viejo (16-12), while the Sailors (18-9) face Millikan (8-17). Each match is scheduled for 7 p.m.
Sage Hill School is the third Newport-Mesa area program competing in the postseason. The Lightning (14-9) play host to West Valley Christian (14-3) tonight at 7.
Each of the three local boys' teams have the coaches to guide them to the top. Conti and Glenn have done it in the past. Thomassen has come close.
While the Sea Kings and Sailors last season suffered second- and first-round exits, respectively, Thomassen led the Lightning to the semifinals.
Glenn previously led Newport Harbor to the Division I title match in 2008, while Conti helped CdM win the Division II championship in 2007.
Division I is more difficult.
"Whoever wins Division I will be a true champion," said Conti, referring to nationally ranked programs like Mira Costa, CdM, Loyola and Esperanza competing in the top division. "Don't be surprised if you see some good teams lose in the first or second round. It's going to happen."
Conti doesn't expect the Sea Kings to go home early. They're coming off a huge five-game victory against Newport Harbor in the Battle of the Bay on Friday.
The match is always an emotional one. The win ensured CdM a No. 2 seed and eliminated Newport Harbor from receiving one of the top four seeds.
Looking at the playoff pairings, Glenn believes Newport Harbor's first-round match isn't as dangerous as CdM's. The Sailors, who finished runner-up in the Sunset League, play the third-place team from the Moore League.
The Sea Kings face Mission Viejo after it defeated Trabuco Hills in a wild-card match Monday. The Diablos reached the semifinals of the Orange County Championships.
"That's a real tough draw for a second seed," Glenn said. "Mission Viejo has probably the best player [Spencer Rowe] in the county and he's going to UCLA. They're one of the biggest teams in the playoffs.
