Regan Smith, a 17-year-old from Lakeville, set a new world record in the 200-meter backstroke during the semifinals at an event in Gwangju, South Korea, early Friday.
The soon-to-be senior at Lakeville North High School already owned the world junior record in the 200m backstroke, but she set it again with a time of 2:06.01 during Friday's heats. That time made her the ninth fastest of all time.
Then she smashed her junior record while also shattering the world record of 2:04.06, set by American Missy Franklin at the 2012 Olympics.
Here's video of the end of her record-breaking swim.
“I’m in shock,” Smith said, via NBC Sports. “I really don’t believe it. I didn’t think I’d ever do that.”
Smith, who won't turn 18 until February, recently committed to swim and study in college at Stanford. She's the No. 1 swimming recruit in the country in the Class of 2020.
According to SwimSwam, Smith "will likely enter her freshman season at Stanford as the favorite to win the national title in both the 100m and 200m backstrokes."
