"Bolt is back"

Mike Costello commentates as Usain Bolt won the 100m at the Anniversary Games in London.

The six time Olympic champion ran a season's best 9.87 seconds in both his heat and the final.

Bolt, who has been struggling for form and fitness, said: "It definitely gives me more confidence knowing that the training I've been putting in is paying off."

Justin Gatlin is still the fastest man over 100m this year with a time of 9.74 seconds.

Asked if he feared the American, Bolt said: "I never fear anybody. I've never backed down from a challenge at any point in my life."
