Cape Town - Caster Semenya has cruised to victory in the 800m event at the Diamond League finals held in Zurich on Thursday.
With a strong field assembled on the night, Semenya led for all of the race putting distance between herself and the chasing pack from the start.
She strode further away from her opposition down the final straight, winning by around eight metres and stopping the clock in a time of 1:55.27.
Semenya was followed home by Ajee Wilson of the United States who took second in a time of 1.57:86 and Natoya Goule of Jamaica who finished third in 1.58.49.
With her victory, Semenya has won her third consecutive Diamond League trophy and is now unbeaten in the 800m event for a period of three years.
She won $50 000 (over R700 000) for claiming the 800m Diamond League title.
Semenya continues to dominate the 800m event despite a new IAAF ruling that from November 1, all athletes classified as "hyper-androgynous" will have to take medication so their testosterone levels can be lowered.
This is applicable for distances from 400m to a mile and will include the 800m and 1500m events, those in which Semenya competes.
