SIOUX FALLS, S.D. – South Dakota swimming and diving established eighth school records and 17 new marks inside the school's all-time top 10 lists on Thursday during day one of the Augustana Invitational held at Midco Aquatic Center.
 
The Coyotes produced four new individual school records and two new relay school records while two previous record holders lowered their times during Friday's competition that saw four individual finals swam, one diving final plus two relays contested for each gender.
 
South Dakota women seven individual events on day one and all four relays, sweeping both the men's and women's 200 medley and 800 free relay events.
 
The women's 50 freestyle school record was broken twice, first in the prelims by sophomore Christina Spomer and then in the finals by sophomore Emily Kahn. Kahn touched in 22.68 in the finals, finishing second in the race, while becoming the first female in school history to break 23 seconds in the short sprint race.
 
Spomer, meanwhile, touched in 23.10 in the finals, finishing fourth after posting a new personal best of 23.07 in the morning prelims that held the school record for roughly seven hours.
 
Zachary Kopp, a senior, lowered his school record in the men's 50 free by becoming the first man in South Dakota school history to go sub 20 seconds, with his time of 19.70 in the morning prelims. He would add a second race under 20 seconds by winning the evening final in 19.81.
 
Cassie Ketterling, a fifth-year senior, grabbed her fifth individual school record in her career with a 54.50 effort in the prelims of the 100 fly and then lowered that time by winning the finals in 54.32.
