Usain Bolt unhappy with 9.91 timing

Jamaican athletics superstar Usain Bolt easily beat compatriot and this season's fastest man over 100m Steve Mullings here on Tuesday at the Golden Spike event.

The 24-year-old world record holder timed 9.91sec, the same time as he ran in the Diamond League event in Rome last week. "My time is not bad, but it could be better. I expected a faster time. It's not even close (to ideal). I have a lot of work to do," Bolt said. Mullings finished second in 9.97sec, shy of his season's best of 9.89sec run in April.
