Australian swimmer James Magnussen has finished last in the 100m freestyle at the inaugural Enhanced Games.
Kristian Gklolomeev won in 46.6 seconds, just outside the world record of 46.4 set by China's Pan Zhanle at the Paris Olympics.
Magnussen was never in contention and clocked 49.44 on Monday (AEST) in Las Vegas, well outside his best time of 47.1 set in 2012.
