China's Pan smashes own 100m freestyle world record for gold
The 19-year-old's time of 46.40 seconds shaved an incredible 0.40 seconds off his previous mark set at the World Championships in Doha in February when he announced himself to the world with a stunning relay leadoff swim.
Australia's silver medallist Kyle Chalmers finished a yawning 1.08 seconds behind the incredible Pan, while David Popovici finished a further 0.01 second behind for the bronze.
There was no easing in for Pan who took off like a rocket and mowed down the opening 50 metres in an outrageous 22.28 seconds.
Any hopes Chalmers and Popovici might have had of catching him were blown out of the water as the Chinese sensation stretched his lead and flew to the wall.
