Usain Bolt says there is plenty of room for improvement after making a winning return to 200 metre action on Saturday.

The Jamaican, who holds the world record over the sprint distance, as well as in the 100m, posted a time of 20.20 seconds to win his first 200m race in 20 months at the UTech Classic in Kingston.

However, the six-time Olympic champion was disappointed not to have dipped under the 20-second barrier - with his record standing at 19.19secs.

"It wasn't the perfect race so I will have to go back and look to see what to improve on," said Bolt, who last covered the distance at the 2013 World Championships in Moscow.

"It didn't feel as smooth as I am used to, but I just need to run more races to get race sharp."

This year's World Championships take place in Beijing in August.
