Australian world record-breaking swimmer Cam McEvoy has had a clear dig at the inaugural Enhanced Games.
Greek swimmer Kristian Gkolomeev went under McEvoy's 50m freestyle world record time at the Games, held on Monday (AEST) in Las Vegas.
Gkolomeev also won the 100m freestyle, while Australia's James "The Missile" Magnussen finished last out of four swimmers in the two races.
That prompted a social media post from McEvoy, who broke the official 50m world mark in March, which read "Seriously?! That's all you got!"
The controversial Enhanced Games and their pro-doping ethos have been widely denounced by world sporting authorities.
Gkolomeev clocked 20.81 seconds, bettering the 20.88 world mark set by McEvoy. But the time will not count because he took banned substances.
