Usain Bolt: ‘This a big deal, a great accomplishment’

Five days after beating Justin Gatlin to win the 100 metres, the 29-year-old Olympic champion and world record holder again proved too strong for in-form American, who finished second in 19.74.
“I am just happy, I told you guys I would do it. There was no doubt. I was not really focused on time. I knew I was not in the shape for a world record.” Bolt, who had run only one race at the distance coming into the championships after an injury-disrupted season, was in control from the start.
