Australian swim star Kaylee McKeown has broken a second world record in the space of two days at the World Cup meet in Budapest.
The 22-year-old Queenslander bettered her own 100m backstroke record on Saturday (Sunday AEDT) with a time of 57.33 seconds, shaving 0.12 off the mark that she in Adelaide before the Tokyo Olympic Games.
It follows her record-breaking swim on Friday evening when she clocked 26.86 for 50m backstroke, eclipsing the previous record of 26.98 set by China's Liu Xiang in 2018.
