British sprinter Dwain Chambers has set a season's best of 10.06 seconds in the men’s 100m heat, and if he can follow that with another good performance tomorrow he will automatically qualify for next month’s World Championships in Moscow.

Dai Greene was also in action tonight at the Alexander Stadium. He won his men’s 400m hurdles heat in 50.51 seconds, as he looks to get back into form following injury and illness.
