In the finals, lost to Byron Nelson 25-18, 25-19.
Last year, Redondo had a semifinal win over Mira Costa and also lost to Byron Nelson in two sets.
“This was certainly a splendid start of the season for us, going 9-1 and making the finals,” Redondo coach Tommy Chaffins said. “We have 17 returning players, so we have a veteran team and with many, many skilled players.
“We look forward to getting back into the gym next week and continuing to refine our game.”
Abby Zimmerman, Taylor Boice and Rowan Devore earned all-tournament honors.
