It's not every day that a Cardinal athlete sets a world record, so this is worthy of our attention.
From U of L:
University of Louisville senior Kelsi Worrell set both a World and American record in her first night of competition at Duel in the Pool in Indianapolis
The American 400-Medley Relay team of Courtney Bartholomew (56.08), Katie Meili (1:02.88), Kelsi Worrell (55.01), Simone Manuel (51.23) combined for a World Record time of 3:45.20. Manuel had to hold off a charging Ranomi Kromowidjojo to clinch the Americans' team win with her anchor leg. Europe finished in 3:45.
