Caleb Ndiku also bounced back after disappointment. The world indoor 3000m champion was spiked in Lausanne on his season debut and wound up 11th. But after making a speedy recovery, he appeared to be back to his old self in the 3000m tonight. Always in contention throughout, Ndiku ran a final kilometre of 2:28 to win in a world-leading 7:35.13, finishing more than a second ahead of Ethiopia's Yenew Alamirew.
Bershawn Jackson notched up his third IAAF Diamond League win of 2015, winning the 400m hurdles in 48.23.
Meeting record for Gatlin on 100m
The other meeting record of the night came in the men’s 100m. Even before the half-way point, it was clear Gatlin was headed for victory and he eventually crossed the line in 9.78 (-0.3m/s), taking 0.04 off the meeting record set by Asafa Powell in 2008. Fellow US sprinter Tyson Gay was second in 9.98 with France’s Jimmy Vicaut taking third place in 10.03.
