Usain Bolt finished his season with a comfortable victory in the final Diamond League meeting in Brussels on Friday.
The Olympic and world champion clocked 9.80 seconds, beating American Michael Rodgers (9.90s) and compatriot Nesta Carter (9.94s) to win.
Afterwards, Bolt told BBC Sport that, despite winning three golds in Moscow last month, 2013 hadn't been his best season because of injury.
"The best thing is I finished on top. My start felt better but I need to work on it. I can definitely run faster."
James Dasaolu, who ran the second-fastest time by a Briton earlier this year, finished eighth.
