Cameron McEvoy will head to the Rio Games brimful of confidence after storming to the Australian 100 metres freestyle title at the Olympic trials yesterday but former world champion James Magnussen failed to book his ticket for the blue riband event.

McEvoy, runner-up at the world championships in Kazan last year, was lightning out of the blocks and posted a time of 47.04 seconds, the fastest recorded since synthetic suits were banned at the end of 2009.

The swim also eclipsed compatriot Eamon Sullivan’s mark of 47.05 seconds at the Beijing Games in 2008, a then-world record only bettered by Alain Bernard (46.94) and current holder Cesar Cielo (46.91) in synthetic suits the following year.

Junior world champion and runner-up Kyle Chalmers was nearly a second behind McEvoy but booked the second Olympic berth in the individual event.

The 17-year-old upstaged James Roberts and fourth-placed Magnussen, who was crestfallen after failing to qualify in his favourite event on his 25th birthday.

A hot favourite to win gold at the last Olympics, Magnussen was pipped by American Nathan Adrian for the London gold and spent much of the intervening years speaking of redemption at Rio.

But he missed last year’s World Championships to have major shoulder surgery and suggested he had lost his race to be fit for the trials.

“Tough race, I’d done everything I could physically to get back in shape,” said Magnussen who is nicknamed “The Missile”.

“Obviously, pretty shattered, but I’ll just go home, soak that in and get ready for the 50 (metres freestyle) again.”
