Great Britain's Adam Gemili insisted there is more to come ahead of the men's 200m final at the World Championships.
The 25-year-old reached Tuesday night's final at the Khalifa International Stadium after qualifying fourth fastest.
He ran a season's best of 20.03 seconds and remains in contention for a first individual world medal, having won gold with the 4x100m relay squad two year ago.
Gemili said: "I am still not firing 100 per cent but I am getting there. I wanted to win that semi and get a good lane for the final.
"I've been saying it for years, once you get in the final anything can happen. It's a clean slate and people can make mistakes. For me, I am going to run to the best of my ability."
Zharnel Hughes suffered further disappointment though as he missed out on the final having come sixth in the 100m final on Saturday.
"My mind is starting to develop over that but it makes me stronger, each year I try to come back and give my very best," he said.
"I might have been down in this Championships but I'm still not out – So next year I just have to work harder and get my body stronger to be able to take on the rounds."
But Miguel Francis was forced to pull out after suffering a quad strain in Sunday's heats.
Meanwhile, Dina Asher-Smith's hopes of a 200m gold medal continued to rise after several rivals pulled out.
Defending champion Dafne Schippers has withdrawn with an adductor problem and the Ivory Coast's Marie-Josee Ta Lou who won 100m bronze is also out injured.
New 100m champion Shelly-Ann Fraser-Pryce will not run while and Nigeria's Blessing Okagbare was disqualified for stepping out of her lane in heat five on Monday.
Asher-Smith won silver in the 100m, breaking her own British record to set 10.83 seconds, but denied it eased any pressure.
"I wouldn't call it a relief. I don't think about it like that, I'm not a negative person," said Asher-Smith, who ran 22.32 seconds in her 200m heat to progress to Tuesday's semi-finals.
"I've never really get nervous, not since 2013 but I definitely get adrenaline which is good.
"That means it's all within my control. But no I wasn't nervous because I knew that I had it within me."
