Yohan Blake, Tyson Gay into 100m final

Yohan Blake and Tyson Gay finished first and second respectively to book their places in the final of the men's 100m this evening.

Jamaica's Blake, who is a training partner of Usain Bolt, clocked a time of 9.85 seconds, finishing just ahead of American sprinter Gay.

Britain's Adam Gemili finished third in what was only his second ever race at an Olympic Games. The 18-year-old ran 10.06 seconds, which was not enough to claim one of the fastest runner-up places.

The final is due to take place at 9.50pm tonight.
