Cricket, sprinting and the Bolt brothers

There is also the supreme self-belief of a man who can showboat his way through the last 30 metres of an Olympic sprint final. Poise, audacity, arrogance – call it what you will. But it is a crucial element in the make-up of a sporting champion. And it seems to run in the family ... Usain's brother Sadiki has revealed his armour-plated conviction that he will play cricket for the West Indies one day.

..."My brother [Usain] is actually a decent bowler. He's got height and a lot of pace. In fact he bowled Chris Gayle in a charity match last year, and Chris wasn't trying to get out – he was genuinely beaten.

For the past five years, the two brothers have lived together in the smart Kingston suburb of Norbrook. Sadiki reciprocates Usain's interest in cricket by joining his brother at sprint training. Or, at least, he does when he wakes up in time ... Other than that, Sadiki says that the pair of them spend a lot of time "just chilling" ... "Sometimes we hit the club – there's a nightclub called Fiction not far from where we live, but if we don't feel like going out we just play dominoes or video games."
