Jamaican sprinter Yohan Blake gave a big boost to beleaguered Glasgow 2014 chiefs last night after hinting he may target a double victory at the Commonwealth Games.

The second-quickest man of all time also urged rival Usain Bolt to sign up for a Hampden showdown.

The 24-year-old, who wrestled the world 100m title away from his fellow Jamaican in 2011 and took silver at the Olympics, cruised to victory yesterday over 150m at BT Great CityGames in Manchester.

Blake admits the chance to chase multiple golds is too good to pass up.

"I'm going to have to talk to my manager and my coach but I will probably double up," he said.

Bolt is not expected to make a final decision on Glasgow 2014 until after the Jamaican trials, but Blake would welcome a head-to-head duel for the title. "I always love to run with him," he said. "We are good friends as well as competitors on the track."

Eilidh Child believes she now has a fight on her hands to be the UK's top hurdler after being pushed into second place in the 200m hurdles in Manchester by English rival Meghan Beesley.

But Child believes a scrap to be No 1 will stoke her competitive fires.

"Meghan and I have been rivals for so long," she said. "She's just been over-shadowed. I know she's quick."

o Grant Sheldon sealed his spot in Scotland's triathlon team for the Commonwealth Games with 13th place at the World Series leg in Yokohama.
