Usain Bolt marked his return from injury by winning the 200 metres at the London Diamond League meet in his final race before heading to Rio in search of three more Olympic titles.
The world's fastest man ran 19.89 seconds on Friday (Saturday AEST) at the Olympic Stadium he left with three golds four years ago during the London Games.
It was Bolt's first race since pulling out of the Jamaican Olympic trials earlier this month with a hamstring injury.
Bolt rarely has anything to prove to anyone.
But the six-time Olympic champion had to show in London that he hasn't been slowed by the hamstring problem.

In his first 200-metre race of the season, the world's fastest man ran 19.89 seconds at the Olympic Stadium he left with three golds four years ago during the London Games.
"I'm not fully in shape. I need more work but over time I will be fine," Bolt said.
"I could feel the rust. The execution I think up there wasn't perfect but it was my first run so I can't complain."
The only complaints Bolt had were targeted at American rivals who had lightly suggested - not strongly - that he got preferential treatment by being allowed to skip the Jamaican trials.
"I felt it was a joke," Bolt said.
"I felt it was a disrespect the fact they think I'd back out of a trials. Me, Usain Bolt who has proven myself year (after) year that I'm the greatest.
"I laughed when I heard it. I was disappointed, especially in Justin Gatlin."
