Olympic 100m champion Usain Bolt ran his fastest time of the season to claim victory at the Diamond Grand Prix meeting in Monaco last night.
The 24-year-old started poorly and after 40m was behind fellow Jamaican Nesta Campbell, before finishing strongly to clock 9.88 seconds.
"It was not the best start, but I executed well overall," Bolt said.
"My last 60m have improved dramatically. I need to work on my reaction time, but I've been doing great in training, so I'm just focusing and I feel ready.
"My aim this season is to run 9.7, maybe 9.6. For me, this year it's about building myself and go into the Olympic season fit and ready. London  is the key."
There are four Diamond League meetings remaining this season, with the competition heading to London on August 5.
