Powell – over 70 sub-10 100m performances

THE Alexander Stadium in Birmingham played host to its first two sub-10 clockings but for Asafa Powell, this is a regular occurrence as the former world record-holder notched up his 70^th and 71^st sub-10 clockings. In far from ideal conditions, Powell sauntered to victory in the heats in 9.95, before accelerating to a 9.91 clocking in the final ahead of compatriot Michael Frater.

This is how Powell's reached 71 sub-10 clockings for the 100m
