100m

Simbine upstages Blake

Blake was the favourite to be crowned men's sprint champion at Carrara Stadium, but the Jamaican could only take bronze after he failed to recover from a poor start and South Africa's Simbine eased to victory in 10.03 seconds ahead of compatriot Henricho Bruintjies.

Ahye became the first woman from Trinidad and Tobago to win 100m gold, crossing the line in 11.14secs ahead of Jamaica duo Christania Williams and Gayon Evans on the Gold Coast.

Thompson fastest qualifier for women's 100m world final

With the defending world champion Shelly-Ann Fraser-Pryce pregnant and not in London, Thompson is the runaway favourite to follow up her 2016 Olympic 100m title with another gold medal.

The Jamaican has recorded the two fastest times this year and she showed her proven class by bursting out of the blocks in her semi-final.

Thompson won in a fine time of 10.84 seconds ahead of Brazil's Rosangela Santos, who set a South American record in second, and she will be hard to stop in Sunday's showpiece final.

Bolt begins farewell with victory

The Jamaican icon, an eight-time Olympic champion with 11 world titles, will hang up his spikes following the championships and clocked a time of 10.07 seconds to advance to Saturday's semi-finals.

Bolt bowed to the fans before setting off in the sixth and final heat, but only crossed the line first - seemingly leaving plenty in the tank - after starting sluggishly.

It was the eighth-fastest time of the night and the 30-year-old was clearly unimpressed, shaking his head after looking at the replay on the big screen.

Bolt wins final 100m before Worlds

The reigning Olympic champion clocked a season's best time of 9.95 seconds - sub-10 seconds being his target heading into the race - beating Isiah Young and Akani Simbine to first place in the standout event at the Stade Louis II.

After a slow start, Bolt pulled away from the rest of the field to bow out of the Diamond League in victorious fashion.

Having struggled with a back injury this season, Friday's win will be a boost for Bolt ahead of his final race before retiring at the World Championships.
