Christian Malcolm's hopes of winning a medal in the 200 metres at the World Championships were dashed as Greece's Olympic gold medallist Konstadinos Kederis triumphed in Edmonton.

The 22-year-old Welshman finished fifth in 20.22 seconds, Kederis won in 20.04secs while Coventry's Marlon Devonish was last in 20.38secs.

Jamaica's Christopher Williams took silver from Kim Collins of the St Kitts and Nevis Islands, with American Shawn Crawford fourth. They all clocked 20.20 in a blanket-finish just behind Kederis.

Malcolm had gone into the final with high hopes of becoming the first Brit in history to win a 200m title at world or Olympic level.

The Cardiff AAC runner had twice shattered his Welsh record in the previous rounds to move into second-place on the British all-time list with a time of 20.08 in the semi.

But Malcolm, fifth in last year's Olympic final and seventh in the 100m at the worlds earlier in the week, was unable to step-up a gear in the final.

The world indoor silver medallist missed out on the medals after fading in the final 20 metres and was clearly disappointed at missing out.

Kederis dominated the race as he added the world title to the Olympic crown he unexpectedly won in Sydney last September.

The real excitement came as Williams, Collins and Crawford, the world indoor champion, all stopped the clock at the same time.

Williams was given the silver and Collins the bronze but after a further study of the photo-finish the judges decided that Collins and Crawford would share a medal.

Kederis said: "In the 200m you have to run the whole race full out, there is no time to rest.

"I tried to be fast but relaxed in the first half of the race and then go as fast as I could in the finish."

When asked about the absence of defending champion Maurice Greene and 1997 winner Ato Boldon from the field due to injury, the Greek said: "It is not my problem whether Ato Boldon or Maurice Greene are running against me. It is theirs."

A dejected Malcolm left without speaking to reporters, and Devonish could understand why.

"He came for a medal. He had the second fastest time (in the semi-final). On paper you expected him to get a medal.

"But he's had a lot of races. This is his eighth. Perhaps it's one race too many."

Devonish said he had targeted a medal himself after a good run in the semi-finals.

"I felt I had a realistic chance to get a medal. If I ran my own race and hopefully come home in the mix, but it didn't happen.

"The competition was all in the middle and that brings out the best in people. I'm disappoined but what can you do."

Devonish instead turned his thoughts towards the 4x100m relay which begins on Saturday.

"We'll try our hardest to bring home a gold medal, but it's going to be hard," he said.
