Regan Smith has set a world record in the women’s 100-meter backstroke at the U.S. Olympic swimming trials in Indianapolis. Smith touched in 57.13 seconds, easily beating the mark of 57.33 set a year ago by Australia’s Kaylee McKeown. Smith bounced back emphatically after getting edged for a spot on the U.S. team in the 100 butterfly, where she finished third behind Gretchen Walsh and Torri Huske. No one was beating Smith in her signature event. Katharine Berkoff claimed the second Olympic spot with a time of 57.91. In the night’s other final, reigning Olympic champion Bobby Finke won the 800 freestyle, holding off teenager Luke Whitlock.
