IRVINE, Calif. — American Kate Douglass set a world record in the 50-meter freestyle preliminaries Saturday at Pan Pacific Championships, going 23.49 seconds and setting up a titanic duel between her and former world record holder Gretchen Walsh in the evening’s finals.
The freestyle mark is Douglass’ second world record of the meet. She led the Americans to a world record in the 4×100-meter mixed medley relay Wednesday night, splitting a blistering 51.01 on a relay start. She was one-hundredth off the individual world record in the 100-meter freestyle Friday night, leading off the 4×100-meter freestyle relay in 51.69.
Douglass and Walsh traded the 50-meter freestyle world record earlier this summer. Walsh held it at 23.55 before Douglass’ preliminary swim. Walsh went 23.78 in preliminaries. Douglass and her were the top two qualifiers.
The 24-year-old Douglass, capable of setting world-class times in the 50-meter freestyle and 200-meter breaststroke alike, is one of the most versatile swimmers in the world. She has five Olympic medals over the past two Games, including an individual gold in the 200-meter breaststroke.
Douglass has three medals so far at Pan Pacs: gold in the mixed medley relay and 4×100-meter freestyle relay and silver in the 50-meter butterfly. She swam the 100-meter breaststroke instead of the individual 100-meter freestyle and finished fourth.
