Cameron McEvoy is the reigning men's 50m freestyle Olympic champion

Cameron McEvoy says it is "crazy" he has not received a financial reward for setting a world record in the men's 50m freestyle at the China Open last week.

The Australian clocked 20.88 seconds in Shenzhen, beating Cesar Cielo's time of 20.91 which the Brazilian set 17 years ago during swimming's 'supersuit' era.

McEvoy, 31, said the "harder pathway" to his historic victory was in "stark contrast" to the $1m bonus promised to swimmers (£745,000) if they break the 50m freestyle world record at the Enhanced Games.

The inaugural Games, which take place in Las Vegas in May, allow athletes to take banned performance-enhancing drugs under medical supervision.
