Cate will get a rematch with Redondo for the CIF-SS Northern Division girls lacrosse title.
The Rams earned another title shot after beating Agoura 17-13 in a semifinal match on Friday at Cate.
Alexis Hill score nine goals and Annie Weis added four, as the Rams improved to 11-3.
“Agoura put up a great fight and could never be counted out of this game,” Cate coach Linda Sommers said. “While we looked a bit shaky on the defensive transtition, a great job was done this group of girls, many of whom had a gruelling week of advanced placement tests and were facing the SATs the morning after this game.”
The title match against Redondo will be played at a neutral site on Tuesday or Wednesday.
