Records fell at the FINA Swimming World Cup on Saturday as Canada's Summer McIntosh set a world junior mark in the women's 400-metre medley and American Katie Ledecky set a world record in the women's 1,500 freestyle.
McIntosh opened the evening session at the Toronto Pan Am Sports Centre with a time of four minutes 21.49 seconds to lead a Canadian sweep.
"Throughout the entire race I felt really in control and strong so I'm really happy," she said.
McIntosh trimmed nearly two seconds off the previous world junior mark set by China's Shiwen Ye (4:23.33) in December 2012.
Sydney Pickrem of Halifax was second in 4:28.45 and Bailey Andison of Smiths Falls, Ont., was third in 4:29.36.
In the next final, Ledecky — who doesn't compete in short-course events very often — won gold in 15:08.24 to take nearly 10 seconds off the previous world best in the 1,500 free.
Beatriz Dizotti of Brazil was second in 15:48.82 and Laila Oravsky of Barrie, Ont., was third in 16:16.86.
McIntosh edged Ledecky in the 400 free on Friday night. The 16-year-old from Toronto won in 3:52.80 — the second-fastest time in history — to break her own Canadian short-course record.
Germany's Sarah Wellbrock set the previous 1,500 free world record (15:18.01) in November 2019.
Competition continues through Sunday evening. The World Cup circuit continues next weekend in Indianapolis.
