Crescenta Valley sophomore Yumi So also left her mark in the league record books, achieving new high marks in the 200 individual medley (2:07.11) and the 100 butterfly (56.20).
"This really is the year of Sara Sun, but I think the next two years in this league are going to be the years of Yumi So," Falcons girls' Coach Robert Miller said of So, who broke the 100 butterfly record by 2.43 seconds, and the medley record by 2.44 seconds.
The Falcons girls' 200 medley relay team, consisting of Sun, So, Michelle Du and Kathryn De Jong, also eclipsed the previous league mark in that race of 1:55.62 with a time of 1:54.73.
The most dramatic, and perhaps most unexpected, triumph for the Falcons came with the boys' edging of Arcadia to claim a share of the title.
Having lost an opportunity to clinch against the co-champion Apaches on April 25, the Falcons boys tallied 486.5 points to Arcadia's 479.5 on Thursday.
Sparked by its victory in the 200 medley relay (1:43.42), Crescenta Valley held a slim lead going into the final events of the day, during which the win was sealed.
Jason Kim swam to victories in the 100 backstroke (55.53) and 100 breaststroke (1:02.06).
In the final event of the day, the 400 freestyle relay, the Falcons placed second (3:21.37) behind Burbank, but beat out Arcadia.
"We came into the season way down," Falcons boys' Coach Jan Sakonju said of being without some top upperclassmen, who either chose not to swim or were ineligible. "From the beginning, it's been about closing that gap so that we can be where we are right now.
"Those guys really stepped it up, and I'm the proudest of this team, maybe, of any of the teams I've ever coached."
Glendale finished fourth behind Burbank in the meet with 199.5 points in the boys' field, and placed third in the girls' with 375.
The Nitros' girls were paced by Katalina Sher, a double winner in the 200 (1:57.63) and 500 freestyle (5:12.09), and Casey Sripramong, who won the 50 freestyle (25.63).
Sripramong and Sher also led the Nitros to a victory in the 200 freestyle relay (1:44.72).
"I think the most exciting thing is Katalina, who is a club swimmer, helping three pure high school athletes make two automatic relays," said Coach Steen Garberson, whose 200 medley relay team swam a CIF automatic time in the 200 medley relay. "It speaks so well of the kids who are not swimming club, that they are able to step up and compete with that kind of intensity."
