Cameron McEvoy has stamped himself as the fastest swimmer of all-time, powering to an extraordinary world record of 20.88 seconds to annex the 50 metres freestyle landmark that's stood for 17 years.
With his milestone performance over one length of the pool at the China Swimming Open in Shenzhen, Australia's Olympic champion clipped three-hundredths of a second off the mark of 20.91 set by Brazilian Cesar Cielo back in the sport's "supersuit" era in 2009.
