Athletics: James Dasaolu clocks 9.91, becomes second-fastest Briton of all time

LONDON (AFP) - James Dasaolu produced a blistering sprint of 9.91sec to become the second fastest Briton of all time in the 100m semi-finals at the British Championships on Saturday.

Dasaolu ran quicker than even world-record holder Usain Bolt has managed this year (9.94) to catapult himself into contention for a medal at next month's World Championships.

The 25-year-old's time in Birmingham was second only to former Olympic champion Linford Christie's 20-year-old national record of 9.87.

Only Tyson Gay of the United States, his compatriot Justin Gatlin and Jamaica's Asafa Powell have gone quicker this year.
