Bolt, the world and Olympic champion, trailed Powell halfway into the race then used his huge stride to pull ahead and even eased up in the last couple of meters. Powell finished in 9.88, followed by two Americans, Darvis Patton in 9.95 and Michael Rodgers in 9.98.

In his first race since smashing world records in the 100 and 200 at the world championships in Berlin, Bolt did not crush his rivals but still had enough to win ahead of Powell, the former world record-holder.

World champion Sanya Richards of the United States stayed in the hunt for the $1 million Golden League jackpot by powering home for an easy victory in the 400 meters.

Richards won in 48.94 seconds, the fastest time in the world this year. Allyson Felix of the United States, the 200 world champion in Berlin last week, was second in 49.83, and Shericka Williams of Jamaica, the 400 silver medalist, was third in 50.40.

"I stayed in my race and waited till the top when I knew I'd be strong," Richards said. "The jackpot for some reason doesn't add a lot of pressure or stress on me. I'm going in very confident that as long as I execute I know I can win."

Richards needs to win the 400 in the last Golden League meet in Brussels next week to be one of the jackpot winners.

The jackpot goes to the athlete or athletes who win their event in all six of the Golden League meets. The Weltklasse at Letzigrund Stadium is the fifth of six meets.

Kerron Stewart of Jamaica lost her chance for a share of the jackpot by losing the 100 in the first meet since the world championships ended in Berlin on Sunday.

Carmelita Jeter of the United States won the 100 in 10.86, while Stewart finished second in 11.04.
