Greek swimmer Kristian Gkolomeev has gone under the 50m freestyle world record time at the inaugural Enhanced Games.
Gkolomeev clocked 20.81 seconds, bettering the 20.88 world mark set by Australian Cam McEvoy in March. But Gkolomeev's time will not count because he took banned substances.
It was the only sub world-record time set on Monday (AEST) in Las Vegas at the Games, which promotes performance-enhancing drugs.
