Great Britain's sprinting golden boy Jonnie Peacock regained his world title in the T44 100m at the London Stadium on Sunday night.
The double Paralympic champion had a slow start and faced a strong challenge from US rival Jarryd Wallace, before pulling away in the final 20 metres.
Wallace was then overtaken just before the line as German speedsterJohannes Floors grabbed silver.
Peacock missed the last world championships (Doha 2015) through injury, but won the title at Lyon 2013.
He was expected to threaten the world record on home turf, but his time of 10.75 seconds was short of Richard Browne's top mark of 10.61.
The British star revealed afterwards: "I was feeling some serious cramps in the warm-up and am just thankful I finished the race."
The star of the London 2012 Paralympics then praised the crowd at the London Stadium, saying: "The atmosphere was phenomenal, the best in the world!"
