Video: World's Fastest Man, Usain Bolt, Beaten By Justin Gatlin in Rome

Justin Gatlin beat Olympic champion Usain Bolt by one-hundredth of a second to record a surprise 100m win in Rome.

Bolt, 26, was fastest out of the blocks at the Diamond League meeting but American Gatlin, 31, powered past the Jamaican to win in 9.94 seconds...see video after cut ..

"I need two months to get ready so I am not worried," Bolt told BBC Sport.

Bolt had suffered a hamstring injury last month which hampered him in his opening race of the season in the Cayman Islands, where he could only manage a time of 10.09 seconds.

And although the six-time Olympic gold medallist, who was making his first appearance in the Diamond League this season, jumped well out of the blocks, he was blowing hard by halfway as Gatlin began to impose himself on the race.

However, the American had to dip his head on the line to beat the world record holder, with France's Jimmy Vicaut third in 10.02 seconds.
