( CNN ) -- World and Olympic champion sprinter Usain Bolt had to battle hard to win the 100 meters race at the Diamond League meeting in Monaco on Friday . The Jamaican , who will defend three titles at the World Athletics Championships in South Korea starting at the end of next month , was far from top form as he edged out compatriot Nesta Carter . However , the 24-year-old still set his season 's best time of 9.88 seconds despite his poor start to the race , while Carter clocked 9.90 . It was 0.3s slower than his world record and 0.1s behind the 2011 leading time by fellow Jamaican Asafa Powell , who heads the series ' point standings . `` I came into the race but did n't execute well . I had to work hard and concentrate , '' Bolt told reporters after his final 100m warm-up before the August 27-September 4 world event in Daegu . `` There are some little things to work on . I have time before the world championships and I will continue to do my best . I 'm almost back to 100 % on the final 60m and I 've got to work on the first half . I 'll take it one step at a time and hopefully the next race will be better . '' American Michael Rodgers was third in 9.96 ahead of a third Jamaican , Michael Frater , who clocked 10.01 . In the men 's 400m hurdles , Olympic champion Angelo Taylor defeated fellow American Bershawn Jackson while Britain 's David Greene was third .
