FEDERAL WAY, Wash. — BYU women’s swim and dive rewrote two school records on Tuesday as it opened competition at the 2025 Big 12 Championships at Weyerhaeuser King County Aquatics Center.
“I’m thrilled with how our teams performed on the first night of the meet to set the stage for the week,” said BYU head swim and dive coach Tamber McAllister. “Our women set a goal to rewrite as many team relay records as possible at this meet, and tonight they did an outstanding job of stepping up and starting us off strong.”
The Cougars started the meet off strong with a school-record 1:38.94 in the 200 medley relay. Emma Marusakova led off for BYU with a 25.72 in the 50 back followed by Mackenzie Miller Lung’s 26.64 50 breast, a 23.98 in the 50 fly from Sarah Eliason and Halli Williams’ anchor 50 free of 22.60. Together, the Cougar foursome finished sixth.
Marusakova, Miller Lung, Eliason and Williams’ new school record overtook the previous mark of 1:39.03 set in 2021 by Brynn Sproul, Katie McBratney, Charlotte Fie’eiki and Gwen Gustafson.
Just one swimming event later, the BYU women had themselves another broken school record.
The Cougars’ 800 free relay team entered Tuesday’s championship ranked ninth in the Big 12 with a season-best time of 7:27.34. Haylee Tiffany, Kara Martinson, Regan Geldmacher and Victoria Schreiber combined to win heat one and finish fifth with a school-record 7:13.87, an improvement of nearly 13.5 seconds. The squad not only vastly improved its season-best time but jumped the school record set a season ago by over five seconds.
Tiffany led off the distance relay with a personal-best 1:48.65 in the 200 free. Martinson and Geldmacher followed in 1:48.74 and 1:48.38, respectively, before Schreiber anchored at 1:48.10. Tiffany’s 1:48.65 ranks her ninth all-time at BYU in the women’s 200 free.
Another individual top 10 time came during the morning’s time trials with Lucy Warnick clocking a personal-best 1:02.19 in the 100 breast, good for No. 7 on the BYU record boards.
BYU women’s diving opened its Big 12 Championships with a fourth-place finish in the team diving event at a score of 268.70. Brooklyn Larson Clouse, Alexia Jackson Hansen and Sophia DeBergh combined to compete in team diving.
"While both our dive teams were just shy of some hardware, they did excellent under high energy conditions and top level competition," said BYU head dive coach Tyce Routson.
After day one, BYU is tied for fourth with Utah and TCU at 150 team points. The Cougars resume competition Wednesday at 10 a.m. PST as preliminary races get underway with the 500 free.
