Regan Smith swam the sixth-fastest 100m backstroke in history, completing yet another impressive meet in Des Moines on Saturday.
Smith, a Minnesota high school senior, won the 100m back in 58.18 seconds at a Tyr Pro Series stop.
Smith, who lowered the world record to 57.57 leading off a relay at the 2019 World Championships, beat a field that included former world-record holder Kathleen Baker (second in 58.56) and world bronze medalist Olivia Smoliga (third in 59.25). Full Des Moines results are here.
That trio should gather again at the U.
