The fastest man in world rugby 7s Carlin Isles will be challenged this season.

Isles clocked 10.13 seconds on the tracks but the latest Australia Men’s 7s recruit Trae Williams ran 10.10 seconds.

Just like Isles, Williams is also a sprinter turned football and the 22 year is the fifth fastest Australian of all time.

Williams who is also known as ‘Quadzilla’ will be unleashed at the Dubai 7s on Friday and he is already challenging USA speedsters Isles and Perry Baker.

‘I think that’s the game I’m excited to play obviously to go out there and show these boys Perry Baker and Isles just to get a matchup between me and him would be really good’.

Williams wish will come true as Australia is pooled with USA in Dubai.

Aussie 7s coach Tim Walsh is impressed with his new 7s find.

‘He’s pretty remarkable and we would want to be able to unleash that and sought of build combination and cohesion throughout this season’.

We can certainly watch the Williams and Isles showdown at 3:12am on Saturday when Australia takes on USA.
