Kaylee McKeown, Regan Smith both go under world record at Westmont World Cup

The World Aquatics Swimming World Cup concludes next weekend in Toronto, live on Peacock.

Australian Kaylee McKeown and American Regan Smith each went under Smith's short-course world record in the 200m backstroke Sunday, the latest chapter in their yearslong rivalry.

McKeown, who swept the backstrokes at the last two Olympics, clocked 1 minute, 57.87 seconds at a World Cup in Westmont, Illinois.

Smith, who held the previous world record of 1:58.04, charged home to nearly catch McKeown in 1:57.91.

McKeown and Smith combine to share the six world records in the backstrokes (50m, 100m and 200m in 25-meter and 50-meter pools). Each owns three.

Most major meets, like the Olympics and World Championships in the summer, are held in 50-meter pools.

Also Sunday, Australian Lani Pallister swam the second-fastest women's short-course 1500m freestyle in history -- a 15:13.83.

Katie Ledecky holds the world record of 15:08.24 from 2022, the only time she has ever contested the event in short-course meters.

Pallister, 23, nearly beat Ledecky in the long-course 800m free at this past summer's World Championships. Pallister finished 36 hundredths of a second behind in an event that Ledecky hasn't lost at a major meet in her career.

The World Cup concludes in Toronto from Friday through next Sunday with daily prelims (10 a.m. ET) and finals (6 p.m.) live on Peacock.
