Usain Bolt won the 100 metres at the Ostrava Golden Spike meeting on Tuesday although he just failed to improve on the time he set in his first race of the season in the Diamond League last week.

The world record holder and Olympic champion beat the fastest man in the world this year – Jamaica's Steve Mullings – in 9.91sec in Ostrava last night, equalling his time in Rome.

Cuba's Dayron Robles took his favourite sixth lane and won the 110 metres hurdles in 13.14 seconds, but fell short of his shared leading time this year of 13.07 and his world record of 12.87 set in Ostrava three years ago.
