American Trayvon Bromell reinforced his favouritism for gold at the Tokyo Olympics after flying to victory in the men's 100m sprint at Gateshead on Tuesday.

Bromell won the final Diamond League race prior to the Olympics in 9.98 seconds from British pair CJ Ujah (10.10) and Zharnel Hughes (10.13) in second and third respectively.

The victory at Gateshead was 26-year-old Bromell's first-ever Diamond League triumph, following years plagued by injuries.

"I’ll take the win,” Bromell said. “I’m happy to cross the line with no injuries.

"I’m just trying to tune up for Tokyo, stay mentally relaxed and continue to fight."

Bromell started strong and finished well ahead of the field, despite Ujah's surge.

“I know I can do better than that. I want the gold," Ujah said. "This is a different CJ and I am really excited.

"It’s now about getting out to Japan, acclimatising and preparing for the race.”

Switzerland's Ajla Del Ponte won the women's 100m in 11.19 seconds, ahead of Canadian pair Khamica Bingham and Crystal Emmanuel.

Jamaican Elaine Thompson-Herah claimed her career 23rd Diamond League win in the women's 200m in 22.43 seconds.

“I am very pleased. I am going to train, reset and stay focused,” the Olympic champion said.

Britain's Jodie Williams ran second in the 200m before competing in the 400m less than an hour later and finishing second with a personal best 50.94 behind Stephenie McPherson.

Ronald Levy won the men's 110m hurdles in 13.22, while Cindy Sember won the women's 100m equivalent in 12.69.
