Gretchen Walsh set a world record in the women's 100-meter butterfly Saturday night, posting a time of 55.18 seconds in a semifinal heat at the U.S. Olympic swimming trials. Walsh was more than a half-second under world-record pace at the turn and finished strong to eclipse the mark of 55.48 set by Sweden's Sarah Sjöström at the 2016 Rio de Janeiro Olympics. The 27-year-old Walsh, a native of Nashville, Tennessee, who competes for the University of Virginia, will return for the finals Sunday night looking to claim a spot on her first Olympic team.
