Both losses have come in tournament play. Santa Margarita defeated the Sea Kings in three games in the Dave Mohs quarterfinals last month.
"I told the girls after the match it's part of the process," Booker said. "It's something we can build on. We did some really good things this weekend we haven't seen before. It's part of how the season goes. There were amazing teams here and we fought a lot through some tough matches. I'm proud of the girls for that. We just came up short."
Saturday's final matchup with Mater Dei (19-8) was a rematch of a nonleague meeting the teams played in September. Corona del Mar swept, 25-20, 25-10, 25-18.
The Sea Kings fought back against Torrey Pines Saturday to win in three games, 24-26, 25-21, 15-10, in the semifinals and advanced to face Mater Dei again.
Corona del Mar had three game points in the second set against Mater Dei to extend the match. The last came at 30-29, but was snuffed out by a kill from Mater Dei's Ashley Cox.
Corona del Mar also led at 29-28 after Mater Dei hit a ball into the net. But Maddie Frome connected on a winner to tie it at 29. The Sea Kings' first game point was at 27-26 and came on a kill from Hayley Hodson.
Mater Dei rallied back from a large deficit in the first set. Corona del Mar was ahead 10-1 to start the match before the Monarchs went on a 15-5 run to tie the score at 16.
Corona del Mar rebounded to grab a 24-21 lead, but squandered three game points as Mater Dei eventually tied it at 24.
Kelsey Humphreys and Britton Taylor were named to the all-tournament team for the Sea Kings.
"We were excited for the tournament," Taylor said. "We played [Mater Dei] before and after we started out really strong, we let up. We need to keep playing strong the whole match."
In the semifinals, Hodson took over late in the third set. With the score knotted at 10, the freshman outside hitter followed Taylor's kill with a block and two kills to give the Sea Kings match point at 14-10. Another kill from Taylor closed it out.
