MONACO (Reuters) - Usain Bolt ran under 10 seconds for the first time this year as he narrowly won the 100 metres at the Monaco Diamond League meeting on Friday.

The eight-times Olympic sprinting champion was slow out of the blocks, just as he was in his last race in Ostrava last month, and never managed to put a big gap between him and the field.
