Kelsi Worrell


Kelsi Worrell
Kelsi Worrell is an American sprint butterfly and freestyle specialist, and the first woman in history to swim the 100-yard butterfly in under 50 seconds. Born July 15, 1994 to Bob and Erica Worrell, she grew up in Westampton, New Jersey prior to joining the University of Louisville’s swimming and diving team where she’s studying Exercise Science. The American Record Holder is also a multi-time NCAA All-American and National Champion.

High school
Worrell graduated from Rancocas Valley Regional High School in New Jersey, where she was the Team MVP and the Burlington County Swimmer of the Year for four years in a row. Aside from being a three-time state champion in the 100-yard fly, Worrell was also a Senior Nationals Qualifier and a high school All-American in backstroke, freestyle and butterfly events. The summer before her freshman year Worrell was a finalist in the 100-meter free at the Junior National Championships, and qualified for the Olympic Trials in the 100-meter fly.

As a freshman Worrell made an impact right away. Dropping three seconds from her incoming 100 fly time, Worrell broke the Big East record in the event. She won all three of her individual events at the Big East Championships, and she qualified for the NCAA Championships in her first collegiate year. At the NCAA meet Worrell ended up finishing 4th in the 100-yard fly and 26th in the 50 and 100-yard free, earning her her first All-American nod.

Returning as a sophomore Worrell only got better. After focusing as just a sprinter during her freshman, she picked up the 200-yard fly for her third event. Worrell qualified two years in a row for the NCAA Championships, and this time she finished 2nd overall in the 100-yard fly, marking it the best finish of her career. In one of her most events, the 200-yard fly, Worrell advanced to the championship final taking 4th, and set a new school record.

Worrell entered her junior season with big goals set for her team. With one of Louisville’s best squads in program history Worrell started off her meet by leading Louisville to a top-8 finish in the 200-yard free relay before swimming her individual 50-yard free. Worrell finished 3rd in the 50-yard free behind Simone Manuel and Ivy Martin. For her third event of day one, Worrell swam the butterfly leg of the 4×100-meter medley relay that finished in 6th place.

On day two Worrell began the finals session with the 200-yard medley relay. She swam the butterfly leg to give Louisville the boost they needed to finish runner-up. In the preliminaries of the 100-yard fly Worrell became the first woman in history to swim the 100-yard fly under 50 seconds breaking the NCAA, American and U.S. Open Records. In the finals session she dropped her records even further, touching in 49.81, more than a second ahead of the 2nd place finisher.

For her third day at the NCAA Championships Worrell attacked the preliminary heat of the 200-yard fly a little too eagerly, and dropped off the last 50 yards of race. For the championship final Worrell swam the race completely different, taking out the first 100 yards smoother, and dropped two seconds from her preliminary swim to win herself another NCAA title. She finished the meet off with an 11th place finishing in the 4×100-yard free relay.


Worrell completed the butterfly double for the second straight year at the NCAA championships. Her most impressive win was the 100-yard, breaking her own NCAA, American and U.S. Open Records. She touched in 49.43, over a second ahead of second place.

In the 200-yard butterfly, Worrell broke the championship record in the prelims touching in 1:50.61. In the final, she dropped off in the last 50, wbut hung on to clinch gold by .08 seconds.

Worrell was part of both medley relays for Louisville, picking up a silver and bronze in the 400 and 200-yard, respectively. In her third individual event, Worrell just missed out on the podium, finish 4th in 50-yard freestyle.

After taking two NCAA titles in her collegiate season Worrell swam at the 2015 U.S. Nationals in San Antonio. Swimming against the American Record Holder in the event, Worrell edged Dana Vollmer out for the win, nearly breaking 5 seconds. Showing some versatility, Worrell’s second event was the 100-meter back, which set the 14th fastest time in American history and the 9th fastest American of 2015.

Worrell time trialed the 50-meter fly aiming for an American Record. She finished in 25.65 just .15 seconds off of the American Record — her time would’ve been good enough to finish in the top eight of the World Championships. After dropping four seconds from her best time on day four, Worrell scratched the event in finals.

Worrell was nominated for USA Swimming’s Breakout Performer of the year award at the Golden Goggles. She was one of three nominees.

2015 Pan American Games

In Toronto, Worrell earned her first international medals. The first came in the 4×100 freestyle relay. After setting a new meet record in the prelims, USA took silver in the final. Her next was a gold in the 100 meter butterfly. Her finals time was slightly slower than the new meet record of 59.24 she set in the prelims. She completed a trio of medals in the 400 meter medley relay splitting 57.34 on the butterfly leg, helping USA to another Pan American Record.

2015 Duel in the Pool 

In Indianapolis, Worrell became a World Record-holder in the 400 short course meter medley relay. Her butterfly split of 55.01 helped USA to defeat Europe in the event. The same night, she picked up a silver in the 100 short course meter butterfly, breaking the American Record in the process in 55.42. Worrell also swam 200 butterfly, finishing fourth.

On day one of World Championships Worrell helped Team USA (Comerford, Manuel & Ledecky) to a new American record in the 4×100 freestyle relay–3:31.72.  Worrell split a very strong 53.17 on the second leg.

On day two Worrell followed up with a 2nd Worlds medal, bronze, in the 100m butterfly, swimming a new personal best, 56.37.

Day six of competition in the women’s 50m butterfly semi-final, Worrell turned a personal best, 25.57.

Day seven, in the 50m butterfly final, Worrell missed the podium, 4th, but broke the American record with a 25.48.

Day eight in the final of the 4×100 medley relay, Team USA’s Kathleen Baker, Lilly King, Kelsi Worrell, and Simone Manuel teamed up to set a World Record. Baker got the ball rolling on the backstroke split with a personal best 58.54 on the backstroke leg, marking the 5th fastest 100 back ever done by an American. King (1:04.48) kept it close as she battled once again down the stretch with Russia’s Yuliya Efimova (1:04.03), but the Russians took the lead through the halfway mark. On the fly leg, Worrell pulled the USA into the lead with her 56.30, making way for 100 free champ Manuel (52.23) to finish things off as they finished in 3:51.55. That took a half second off the former World Record, which stood as a 3:52.05 done by the USA in 2012.

In Columbus, Worrell picked up two wins. She touched the wall first in the 100 butterfly with the time of 49.87 which broke the Championship Record. Her second win came in 200 butterfly when she beat Grace Oglesby by 1.12 seconds.
