Australian Mollie O’Callaghan broke the short course 200m freestyle world record for the second time in a week on Friday, winning in 1min 49.36sec at the World Cup stop in Toronto.

O’Callaghan sliced 41-hundredths of a second off the world record of 1:49.77 she set in Westmont, Illinois, just six days earlier — a victory that made her the first woman to break 1:50 in the event.

Hungarian Hubert Kos and Canadian Josh Liendo followed up world record swims on Thursday with victories.
