Greene claims hurdles glory
The final of the men's 400m hurdles at the athletics Olympic trials lived up to its billing as one of the best races of the weekend, with five of the eight finalists having achieved the 'A' standard.
World champion Dai Greene shrugged off some poor early-season form to claim victory, with training partner Jack Green also securing his place on the team for London with a late surge to overtake Nathan Woodward and take second.
Woodward's hopes were dashed when he stumbled over the final hurdle, while Rhys Williams crashed to the track after hitting the penultimate barrier. Both will now face an anxious wait to see if they receive the final discretionary place.
Olympic champion Christine Ohuruogu and Shana Cox both secured their place in London by finishing first and second respectively in the 400m, but things were far less clear in the women's 800m.
Marilyn Okoro and Emma Jackson had the 'A' standard but finished fifth and seventh in the final, with Okoro paying for a foolish early pace. Scotland's Lynsey Sharp was a surprise winner ahead of Jemma Simpson, but both will need to run the qualifying time by July 1 to claim their place in the team.
Greg Rutherford sealed his place in London by winning the long jump, but there was bad news for world junior champion Jodie Williams, who left the track in tears after pulling up with an apparent hamstring injury 15m from the line in the women's 100m final.
Teenage star Adam Gemili was again impressive as he powered into Saturday evening's men's 100m final by winning his semi from Harry Aikines-Aryeetey in 10.20s.
Five-time champion Dwain Chambers also advanced after finishing second behind Simeon Williamson in the next heat, with a photo-finish required to separate the pair, while James Dasaolu and Mark Lewis-Francis were also among the automatic qualifiers.
Only Gemili and Dasaolu have the current 'A' standard of 10.18s and can therefore secure their Olympic place by finishing first or second in the final.
Sophie Hitchon, 20, had already achieved the 'A' standard of 71.50m i nthe hammer and therefore needed to finish in the top two here to make certain of being in London, something she achieved comfortably with victory and a best throw of 69.79m.
