Bolt aims to complete world championship grand slam

BERLIN (Reuters) - Usain "Lightning" Bolt will get a chance to break another world record on the penultimate day of the world championships on Saturday.

The lanky Jamaican, who has already bettered his 100 and 200 meters world records in Berlin, returns to the track for the 4x100 relay final.

Bolt and his three colleagues clocked a world record 37.10 seconds to win gold at last year's Beijing Olympics and the disqualification of the United States team here has removed their biggest challengers.

Jamaica and the U.S. are also set to clash in the women's 4x100 relay heats and final on Saturday.

The long jump should be the highlight of the field events with the last two Olympic champions, American 2004 winner Dwight Phillips and 2008 gold medalist Irving Saladino of Panama, in action.

The men's marathon and pole vault and women's hammer throw and 5,000 are also on the schedule.
