Portugal Colonial - Ledecky closes US swim championships with 1,500m free victory

Bobby Finke and Gretchen Walsh also grabbed their third wins of the week in Indianapolis, Indiana, to set themselves up for multiple medal campaigns in Singapore.

Ledecky clocked 15min 36.76sec to win the 1,500m free by more than 25 seconds. Claire Weinstein, who swam in a different heat of the timed finals was second-fastest in 16:01.96.

"I just wanted to put together a pretty even swim, hold a good pace,” Ledecky told NBC Sports.

"That one hurt, but I'll take it, move on to Singapore," added the US great, who also won the 400m and a "really good" 800m free this week and finished second in the 200m free.

Ledecky heads to a seventh World Championships aiming to add to her 21 world titles.

"I'm excited," she said. "I mean, I have been to a lot of these, but I still feel like I get the same excitement, the same energy from the team."

Finke won the men's 800m free in 7:43.13, more than six seconds ahead of Rex Maurer.

Finke, who set the men's 1,500m free world record in defending his Olympic title in Paris, also won that event along with the 400m medley -- although he has indicated he won't swim the medley in Singapore.

Walsh won the women's 50m freestyle in an American record-equalling 23.91sec to close out a stellar week that saw her win the 100m butterfly with the second-fastest time ever and the 50m fly in the fourth-fastest time ever.

Jack Alexy won the men's 50m free in 21.36, the top time in the world this year.

Santo Condorelli, the 30-year-old who has competed in the Olympics for both Canada and Italy, was second in 21.68 to earn a chance to represent the United States for the first time in international competition.

Shaine Casas won the men's 200m individual medley in 1:55.73, just three-hundredths of a second in front of Carson Foster, Casas notching another victory after his triumph in the 100m butterfly.

Alex Walsh won the women's 100m medley in 2:08.45 with Phoebe Bacon taking second in 2:09.22.
