Jamaica's Usain Bolt stars in return from injury

Jamaican track star Usain Bolt returned from a hamstring injury to win the 200 meters at the Anniversary Games meet in London on Friday in his last tune-up prior to the Summer Olympics.

Bolt won the event in 19.89 seconds. It was his initial race since being injured earlier this month in the Jamaican Olympic trials.

Bolt, a six-time Olympic champion, is known as the world's fastest man.

"I'm getting there. I'm not fully in shape," Bolt said afterward. "I need more work but over time, I will be fine. I'll just keep doing the work.

"It wasn't perfect. I came off the corner trying to hold my form. I'm happy with my execution and hopefully my coach is."

Also, Keni Harrison of the United States set a world record by winning the women's 100 meter hurdles in 12.20 seconds.

The previous mark was 12.21 by Yordanka Donkova of Bulgaria in 1988.
