The boys' tournament will continue under the direction of former coach Tim Mang.
"Our girls felt like it was another home match, and [reserving] the courts was getting to become an issue," CdM Coach Brian Ricker said. "I basically gave it to Dana Hills."
Indeed, the Dana Hills Coastal Championship will fill the void.
The Dolphins' tournament, scheduled for Oct. 15-16, will feature top teams like the hosts, CdM and Sage Hill, as well as Laguna Beach, Mater Dei and Troy.
The Dana Hills tournament final will be at the Laguna Niguel Racquet Club.
Sage Hill girls' tennis is also busy. The Lightning scrimmaged Santa Margarita Tuesday and open regular-season play at The Tennis Club Newport Beach on Thursday against another Sunset League team, Los Alamitos.
Sage Hill also hosts the Lightning Invitational on Friday and Saturday, at The Tennis Club.
Coach A.G. Longoria said defending champion Santa Ynez returns, and Cerritos, Tesoro and Sage Hill will also be in the round-robin tournament that concludes at 3 p.m. Saturday.
He said Cerritos may be the favorite this year.
Longoria said he expects Sage, which moved up from CIF Southern Section Division IV, to be in the top 10 in the Division III poll.
Though the results aren't official, they won seven of 10 singles sets against Santa Margarita and all 14 doubles sets.
