In the preliminary round, Toea Wisil was the most impressive, winning with a relaxed 11.60 into a -1.6 mps wind, while Noor Hussain Al-Malki's Olympic experience lasted just the first steps out of the blocks before she pulled up.

Her training partner Blessing Okagbare left an impression by outrunning Tianna Madison for the second best time.

The semi-final round qualifiers was virtual mirror image of the previous evening's heats, the same top athletes with Jeter again posting a 10.83 and 11.01 the number 8 time.

She was quickest from the blocks with Jeter in close pursuit, and she ultimately leaned at the finish line for a narrow victory to defend her title.
