Olympic and world 5,000m champion Meseret Defar underlined her renewed dominance at a distance where she won Olympic gold back in 2004 as she beat her Ethiopian rival Tirunesh Dibaba, the world and Olympic 10,000m gold champion, finishing a couple of seconds clear in 14min 32.83sec.

It was only the third time these two great runners have met in the past four years, although both are due to toe the line at the Bupa Great North Run on September 15 over the half-marathon course on which Dibaba won last year.

And Kenya's newly established world 800m champion Eunice Sum made it clear that her victory over Russia's defending champion Mariya Savinova in the Luzhniki Stadium was no one-off as she once again proved too much for the Russian in the finishing straight, timing her run to the line perfectly to cross the line in 1min 58.82sec.

With their final Diamond League efforts counting double in terms of points, both Defar and Sum claimed the $40,000 (£26,000) cash prize and Diamond Trophy for winning the season-long Diamond Race in their events.

Bolt, who began sluggishly, did no more than he required who st pull clear of the field over the final 20m, finishing clear of fellow Jamaican Nickel Ashmeade, who clocked 9.94, and former Olympic champion Justin Gatlin of the US, third in 9.96. 

The world and Olympic champion, however, did not secure another Diamond Trophy despite his win - the 100m Diamond Race went to Gatlin.

"I think the longer my season goes on, the worse my start gets," Bolt said.
