A new sheriff...published at 20:25 British Summer Time 28 September 2019
Image source, Getty ImagesWhatever you may think of Justin Gatlin, he's just won world 100m silver at the age of 37.
He gets himself on point for the big moments but can't hang on to the gold he won in 2017.
There's a new sheriff in town.
'I wasn't up for it'published at 20:25 British Summer Time 28 September 2019
British sprinter Zharnel Hughes, who finished sixth: "It wasn't the best race for me tonight but hey, congrats to the medalists, all the best to them.
"Those things happen. You have to be strong minded. I am disappointed but I cannot give up on myself, I still have the 200m to come. My body just wasn't feeling up for it."

The start from Christian Coleman was so impressive and there was no eating into the lead he opened up. Not once did he fade or look like he may be sucked back in.
Great Britain's Zharnel Hughes was back in sixth on 10.03, with Jamaican Yohan Blake in fifth at 9.97.

Michael Johnson
Four-time Olympic gold medallist athlete on BBC TVWe saw in the heats what could have been and he certainly delivered. 9.76 puts him sixth all time. We knew this was a quick track and there were questions over him coming in.
He was all by himself. It was never a competition.

Christian Coleman clocks 9.76 seconds, Justin Gatlin 9.89 and Andre De Grasse 9.90.
Wow. Proper sprinting across the lanes.
Coleman crossed the line, looked to the sky and simply roared.

The pantomime villain of athletics Justin Gatlin is home in second, with Canada's Andre De Grasse in third. The front three all 9.90 and under. Full result to come....

The fastest time in the world this year is 9.81. By Coleman. At risk?

BBC Sport commentatorCan anyone challenge Christian Coleman under the lights in the dark in Doha? It's a strange atmosphere - a thin crowd.
But millions of eyes around the world are watching to see this blue riband event to decide the fastest man in the world.

Christian Coleman, hands on hips. This swanky light show sees his name in lights down the home straight. This is very swish I must say.

The light show looks pretty cool. Thankfully it leads to the lights around the stadium being turned out to hide the fact there are about 12 people watching.
