Kip Keino Classic: Ferdinand Omanyala lights up Kasarani

The men's 100m had suffered from the star exit of Olympic champion Lamont Marcell Jacobs who withdrew from the line-up at the last minute because of intestinal problems.

That left meant there would no Olympic rematch between him and Fred Kerley, the American whom he denied gold in Tokyo last summer but Omanyala provided the defining moment with a scorching performance in Kasarani.

Omanyala, who ran 9.77 seconds here last year when he finished second behind Trayvon Bromell, found a great start off the blocks and never ceded his advantage in what turned into a duel with Kerley.

The top four men all ran season bests with Kerley finishing second in 9.92 while Isaiah Young (10.13) and Hendricho Bruintjies (10.13) were third and fourth respectively.
