The Jamaican sprint star surprisingly lost over 100 meters in 2008 and 2010, but the switch to 200 — his preferred distance — reversed his fortunes at the Diamond League event.

In his last scheduled race before he defends his sprint titles at the world championships next month, Bolt was never seriously troubled and cantered over the line well clear of his rivals.

LaShawn Merritt was second in the 400 on his return from a 21-month doping ban, while Caster Semenya’s struggles in the 800 continued as she trailed in eighth.
