Devonish was hoping to get a medal in the 200m

Devonish could only finish sixth in 20.93 seconds in the second semi-final, ensuring no Briton in the 200m final for the first time since 1966.

Chris Lambert and Wales' Christian Malcolm withdrew injured and Darren Campbell was disqualified in the heats.

Jamaican Omar Brown came with a late run to pip favourite Stephan Buckland of Mauritius for gold in the final.

Both men clocked 20.47 but Brown took it in a photo finish and another Jamaican, Chris Williams, won bronze in 20.52, pushing Australia's Patrick Johnson into fourth.

Devonish, who said he "bottled" his 100m final, in which he finished last, described his 200m effort as "not very good".

"In the quarter-final I got cramp in my left calf but I still managed to qualify convincingly," he told BBC Sport.

"I was a bit paranoid about the cramp again but I was very disappointed with my race.

"Before I came here my aim was to get to the 100m final and medal again in the 200, but it doesn't always go to plan, does it?"

England's Chris Rawlinson could only finish last in the 400m hurdles final in his last competitive outing before retiring.

Rhys Williams has proved he is a championship performer Chris Rawlinson

Rawlinson, suffering with a stomach injury, clocked 52.89secs in a race surprisingly won by South Africa's Louis Van Zylin 48.05secs, pipping compatriot Alwyn Myburgh (48.25) and the favourite, Jamaica's Kemel Thompson (48.65).

"I was in a lot of pain warming up and when I tried to push out of the blocks it felt like someone had gutted me," Rawlinson said. "I was in absolute agony."

But there was a superb performance from Wales' Rhys Williams, who set his third personal best of the Games with a new Welsh record of 49.09secs in finishing fourth.

"I would have loved to have got a medal but I am really pleased with that," Williams said.

Rawlinson added: "I have trained with Rhys for a couple of years now and he is a great athlete. He has proved he is a championship performer."

England's Carl Myerscough missed out on a medal in the discus final, finishing fifth with a throw of 60.64m.

Australian Scott Martin took gold with a throw of 63.48m in the final round, pipping Canada's Jason Tunks, who had led from the opening round with 63.07m.

Tunks's compatriot Dariusz Slowick took bronze while England's Chukweumeka Udechuku finished seventh.
