With the time, Bolt improved on his season’s best of 10.05 in the Cayman Islands on Saturday.

Ramon Gittens of Barbados finished second in 10.21, with Iran’s Hassan Taftian finishing third in 10.25. ‘If I can improve that it should be OK’.
After the Caymans race, Bolt had a tight hamstring that forced him to see his doctor in Munich, Germany, but he dismissed all concerns about his fitness ahead of Ostrava.
“From the time I left the blocks, I got a good reaction, I executed well but the power behind the start was not good …”
“I’m definitely going to win in Rio, as long as I get everything right and everything goes smoothly I should be OK, you know what I mean?” he added with a wink. In 2012, he won the 100 in Ostrava in 10.04s, a poor time by his standards, before he won three more gold medals at the London Olympics.
Bolt is next scheduled to race over 100m in Kingston, Jamaica on June 11 against fellow countrymen Yohan Blake, the Olympic silver medallist who has clocked 9.95 this season, and former world-record holder Asafa Powell.
Czech Radek Juska won the event with a distance of 7.92 metres.
Rehm hopes to become the second athlete with a carbon-fiber prosthesis to compete in the Olympics and the Paralympics after Oscar Pistorius in 2012.
But he said the injury had no impact on his performance at Ostrava.
Bahamian Michael Mathieu finished last in 46.83 seconds.
Taftain came third clocking 10.25 seconds.
Young Hyde fell in his 400m hurdles event after clipping the seventh hurdle as he made his way around the 200m bend very much in the thick of the action with the event eventually going to South African LJ van Zyl, 48.67 with Johnny Dutch (USA), 49.01 finishing second and Patryk Dobek, 49.51 ending in third place.
