Usain Bolt is through to the semi-finals of the men's 100m.
The defending champion ran in 10.09 seconds on a lightning fast track in London.
Bolt sounded pretty laid back about his time saying; "I expected it, I'm running well, I'm happy, training is great.
Reaction was good. I'm looking forward to the semifinals."
Fellow Jamaican and world champion Yohan Blake ran 10.00 in his heat to also book his place in the semis.
But it was American Ryan Bailey who posted the fastest time, a blistering 9.88 seconds.
