Day 1, Part 3

Coverage from Osaka of the opening day of the World Athletics Championships, featuring the men's 100m quarter-finals, shot put final, triple jump qualification and 400m hurdles heats. A place in the 100m semi-finals is at stake for the leading male sprinters. Britain's Marlon Devonish reached the last 16 at the previous World Championships and will expect to make comfortable progress here after showing the best form of his career this summer. But the main focus will be on World record holder Asafa Powell and the fastest man of 2007, Tyson Gay.
