On Thursday evening at the 2015 NCAA Women’s Swimming & Diving Championships Stanford freshman Simone Manuel has broken the 17-18 National Age Group Record in the 50 yard free, and also swum the second-fastest time in history, with a 21.32 to win her first NCAA title.

“I was a little nervous,” Manuel said of her swim. “I made a couple mistakes on my relay swim (21.68), so I just tried to focus on some of the things my coach was telling me. At the same time, you don’t want to think too much because you might mess up something else. So I really just tried to go out there and have as much fun as I could.”

That swim broke the 21.49 that Abbey Weitzeil did in 2014 as the fastest time ever done by a 17-18. Weitzeil is still in high school, but Manuel is on the young end of the college freshman range and doesn’t turn 19 until August 2nd.

That swim also is the second-fastest 50 free in history by a swimmer of any age, and at any level. It sits behind only Lara Jackson’s 2009 rubber-suited 21.27: the U.S. Open, NCAA, and American Record in the event.
