The American quartet of Olivia SmoligaKatie MeiliKelsi Dahlia and Mallory Comerford came together to obliterate the world record in the women’s 4×50 medley relay, clocking a time of 1:42.38 to slash 0.89 seconds off the mark of 1:43.27.

That record was set by the American squad two years ago in Windsor who won gold, with Dahlia being the only remaining member from that team.

On the lead-off, Smoliga’s 50 back split of 25.97 broke the American Record set by Ali DeLoof on that 2016 relay. Check out a full split comparison below:

USA, 2016 SC Worlds USA, 2018 SC Worlds
Ali DeLoof – 26.12 Olivia Smoliga – 25.97
Lilly King – 28.78 Katie Meili – 29.29
Kelsi Worrell (Dahlia) – 24.44 Kelsi Dahlia – 24.02
Katrina Konopka – 23.93 Mallory Comerford – 23.10
1:43.27 1:42.38

The runner-ups from China broke the Asian Record once again in 1:44.31, taking down the 1:45.53 mark that they had set in the prelims.

Great swim from USA regardless!
