Allianz Memorial Van Damme

Unbeaten in her four previous Diamond League starts this season, the Puerto Rican was again in imperious form winning by daylight in 12.27, eclipsing the previous record of 12.42 set by Bulgaria’s Yordanka Donkova in 1986.

The quality of the race was such that Tia Jones, the 2018 World U20 champion, clocked a personal best of 12.38 for second place just edging out former world-record holder Kendra Harrison, who ran 12.40.

Jamaica’s Britney Anderson was fourth in a fast 12.44 while compatriot Megan Tapper ran a lifetime best of 12.51 for fifth.

Earlier Fiordaliza Cofil ran yet another personal best this season clocking 49.80 to win the 400m. The runner from the Dominican Republic surged late to get by a rapidly fading Sada Williams of Barbados who finished second in 50.15.

Belgium’s Cynthia Bolingo ran a new national record and personal best of  50.19 for third place. Mary Moraa of Kenya was fourth in 50.67 a new national record and personal best.

Fraser-Pryce, who complained of a tight hamstring prior to withdrawing from the 100m in Lausanne two weeks ago, ran 10.74 for second after she was edged at the line by Jackson who clocked a meet-record 10.73 for victory.

Afterwards, Fraser-Pryce, who admitted at the pre-race press conference on Thursday that she was not 100 per cent, said she did not suffer an injury during the race but was being cautious regarding her participation in Diamond League final next week.

“I feel okay about today´s race. It wasn´t anything spectacular but I felt good I do not have any injury so that is the most important part,” she said.

“I am not sure about Zurich I will have to wait and listen to my body but today was really amazing. I love running in Brussels.”

Meanwhile, Jackson was obviously pleased to be the only woman to defeat her imperious compatriot.

“It takes a lot of hard work to beat Shelley-Ann. She's a tough cookie to beat,” Jackson declared.

 “So you need to keep working hard if you want to win. Tonight I had a good execution of my race, so I'm happy with that.”
