GIRLS’ HIGHLIGHTS
Cal commit Teagan O’Dell, a senior at Santa Margarita, claimed a pair of titles in the 200 IM and 100 back, both in Division I meet record times.
She opened her meet with a commanding performance in the 200 IM, stopping the clock in 1:53.43—just five-hundredths off her own national high school record of 1:53.38. The swim represented one of her fastest efforts ever, narrowly missing her lifetime best of 1:52.61 from Winter Juniors in Austin this past December.
She won the race by more than six seconds over Fountain Valley senior Kaitlyn Nguyen, a USC commit, who posted the only other sub-2:00 swim of the final with a 1:59.63. That time was just shy of her personal best of 1:58.87, also from Winter Juniors.
In the 100 back, O’Dell logged a winning time of 51.09, coming close to her best time of 50.70. Her back half was particularly impressive, with less than a second separating her splits—opening in 25.17 and closing in 25.92.
Another double event winner of the session was Fountain Valley sophomore Alyssa Ton, who notched two 1st-place finishes, showcasing her middle-distance talent in the 200 and 500 freestyle.
In the 200 free—the first individual event of the day—Ton clocked a personal best of 1:44.12, smashing her previous time of 1:45.37 and successfully defending the section title she won last year in 1:45.96. She followed that up with a 4:43.39 in the 500 free, earning her first section win in the event.
Her 500 was a new career best, taking down her prelim swim of 4:44.54, which had already eclipsed her previous PB of 4:45.33 from November’s CA RMDA Kevin Perry Senior Invitational.
Last year, she opted for the 100 fly instead of the 500, where she placed 7th.
The splash-and-dash saw Mira Costa senior Delaney Herr upstage fellow senior Gracyn Aquinoof Santa Margarita, the top seed. Herr, a Princeton commit, touched in 22.51 to edge out Aquino, a Cal Berkeley commit, who posted a 22.68. Herr narrowly missed her personal best by just 0.01, while Aquino improved on her 22.85 prelims PB.
Valencia junior Tori Yamamura won the 100 fly with a best time of 52.83, moving up from her runner-up finish last year. She outpaced Santa Margarita senior Chloe Stinson (54.62) and Ventura senior Sarah Bechman (54.62), who tied for silver. Yamamura, a Missouri commit, clipped her lifetime best of 52.92 from just two weeks ago after hitting a quick 53.15 in
