Not to be outdone by the Australians, the US women put on a show at night one of the US Olympic Swim Trials. 

The 400 IM proved to be one of the most exciting races of the night with it all coming down to the final 15 meters. As Melanie Margalis faded, 19-year-old Emma Weyant came from behind to touch first with the fastest time in the world this year at 4:33.81.

Hali Flickinger managed to overcome Margalis and post the second-fastest time in the world this year at 4:33.96. 

Each country can take up to two swimmers to the Olympics in each event with the roster size being capped at 26. While it’s likely that Flickinger will be joining Weyant in Tokyo, the roster must first be filled with the rest of the week’s first-place finishers before determining who else will make the team.

Just a few minutes prior, 18-year-old Torri Huske dominated the first semi-final of the 100 fly, out under world record pace and setting a new American Record in a time of 55.78. 

The previous mark of 55.98 was set nine years ago by Dana Vollmer at the 2012 Olympic Games. It also makes Huske the third-fastest performer all-time, behind world record holder Sarah Sjostrom (55.48) and China’s Zhang Yufei (55.62). With one more race to go to determine who makes the Olympic team in the event, it’s possible Huske could move up even further on the list before the Olympics.  

The finals of the 100 fly take place Monday, June 14 with the session starting at 8 p.m. ET.
