The Japan Times - Walsh swims second-fastest 100m butterfly in history at US Championships

Walsh, who settled for silver behind Huske at the Paris Games last year, had lowered her own world record twice at the Fort Lauderdale Pro Swim last month, becoming the first woman to dip below 55 seconds with a world mark of 54.60sec in the finals there.

She was well under world-record pace when she turned in 25.19sec, and even though she couldn't lower the mark, she posted the second-fastest time in history and had plenty to hold off Huske, who finished 1.8sec back in 56.61sec.

"I just like pushing myself past boundaries that I never thought possible," Walsh, who now owns the top seven times in history, told NBC Sports.

She lined up a second individual event at the World Championships in Singapore July 11-August 3 after winning the 50m fly with the fourth-fastest time ever on Wednesday.

Katharine Berkoff also turned up the heat, posting the second-fastest 50m backstroke time in history with her win in 26.97sec. She broke the American record of Regan Smith, who was second in 27.20.

Lilly King, a three-time Olympic gold medallist and an 11-time world champion who has announced this will be her last season, won the 50m breaststroke in 29.88sec.

Bobby Finke ran down Carson Foster to win the men's 400m individual medley in 4min 07.46sec.

He sliced more than two seconds off his personal best to get the better of Paris Olympics bronze medallist Foster, who finished in 4:07.92.

Finke, two-time Olympic gold medallist and world record-holder in the 1,500m freestyle, indicated last month that he wouldn't swim the 400 medley in Singapore even if he qualified because of a scheduling conflict with the events.

"I've got to talk to my coaches about it, but we kind of have a plan in mind," he said.

Emma Weyant, silver medallist at the Tokyo Olympics and bronze medallist at the Paris Games last year, won the women's 400m individual medley in 4:34.81 with Katie Grimes second in 4:37.22.

Shaine Casas led all the way in winning the men's 100m butterfly in 50.51sec.

Quintin McCarty won the men's 50m backstroke in 24.34sec with Casas second in 24.44.

Campbell McKean, 18, won the men's 50m breaststroke in a personal best 26.90, edging veteran Michael Andrew by two-hundredths of a second.
