Diamond League final: Charlie Dobson claims surprise 400m win in Brussels

Meanwhile, Britain’s Dina Asher-Smith narrowly missed out on victory in the women’s 100m.

The 28-year-old, who won silver in the 4x100m relay at this summer’s Paris Games, finished 0.04 seconds behind Olympic champion Julien Alfred of St Lucia, who crossed the finish line with a time of 10.88s.

Alfred’s US rival Sha’Carri Richardson finished eighth in the nine-woman field, having eased off well before the line as victory became out of reach.

Second marks a positive end to the season for Asher-Smith, who failed to reach the final of the 100m in Paris after finishing fifth in her semi-final.

Ivorian Marie-Josee Ta Lou-Smith finished third with Britain’s Daryll Neita fourth.

Elsewhere, Sweden’s Armand Duplantis finished an unbeaten p[ole vault season on a high with a 15th and final victory of the year.

Duplantis set a new meeting record with 6.11m but was unable to improve on his own world record which he set for a 10th time on 25 August with a vault of 6.26m in Poland.

“My legs felt terrible tonight and I’m just really tired,” he said.

“That took a lot more from my body that I expected. With 6.11m I got a good result, but the world record wasn’t meant to be tonight.”

Jamaica’s Ackeem Blake won the men’s 100m in 9.93s ahead of Americans Christian Coleman (10.00s) and Olympic bronze medallist Fred Kerley (10.01s).

Olympic and world champion Marileidy Paulino continued her dominance on the track by winning the women’s 400m.

The Dominican Republic athlete took victory with a time 49.45s.

She is unbeaten in one-lap competition since last year’s Diamond League meet in Silesia, Poland. Ireland’s Rhasidat Adeleke finished third.

Finally, Norway’s Jakob Ingebrigtsen took victory in the men’s 1500m with a time of three minutes and 30.37 seconds, holding off Kenya’s Timothy Cheruiyot and Paris Games winner Cole Hocker.
