Kaylee McKeown has been firing on all cylinders at the 2021 Sydney Open and has now posted the second-fastest long course 100 backstroke swim of all time in the form of a 57.63. The swim is a new Australian and Commonwealth record in the women’s 100 bacsktroke, improving upon her own marks of 57.93 from December 2020.
That swim for McKeown gets her within 0.06 seconds of Regan Smith‘s 2019 world record in the event of 57.57 and replaces her 57.93 as the #2 100 backstroke in history. McKeown is now the only woman to ever break 58 seconds more than once.
