Greg Rutherford was looking to boost Britain's medal haul at the World Championships in Berlin after the team drew a blank on Friday.

Michael Bingham was seventh in the final of the 400 metres and Emily Freeman was also seventh in the women's 200m final after action in the Olympic Stadium was delayed by 40 minutes due to torrential rain.

Bingham had set a new personal best of 44.74 seconds in the semi-final but was unable to reproduce that form from lane eight in the final, clocking 45.56secs.

"It's not that I ran badly but the fact that being in the eighth lane throws you out," said the 23-year-old, who was born in North Carolina but switched allegiances in 2008 through his British father.

"It's my first year as a professional athlete, I have championships ahead of me and this won't happen again."

Freeman had also set a personal best of 22.64s to reach the final but clocked 22.98s as America's Allyson Felix won a third straight title.

"I was tired and tense at the start but I am pleased to get to the final and I would have taken that and a personal best before I came here," Freeman said.

That left Britain with three medals with two days of competition remaining - two short of their target - with Rutherford offering one of the best chances for further glory.

The 22-year-old from Milton Keynes produced a new British record of 8.30m in qualifying to be ranked second behind American Dwight Phillips, and believes there is more to come.

"There is more in the tank, I can jump further than that," said Rutherford. "I'm confident now, this is the biggest boost I ever had."

Middlesbrough's Chris Tomlinson also qualified for tonight's final and will be out to regain his national record from team-mate and training partner Rutherford.

Steve Lewis will also contest the pole vault final and Britain's 4x100m relay team take on the might of Jamaica and Usain Bolt in the final event of the evening.

The quartet of Simeon Williamson, Tyrone Edgar, Marlon Devonish and Harry Aikines-Aryeetey clocked 38.11 seconds as they chased home fastest qualifiers the United States (37.97secs), who were then disqualified for an illegal baton change on the final leg.

Jamaica, without Bolt or 100m bronze medallist Asafa Powell, also qualified but two of the exchanges between Lerone Clarke, Michael Frater, Steve Mullings and Dwight Thomas were far from fluent as they finished second behind Italy in 38.52s in the third semi-final.

Edgar said: "We are pretty happy to get to the final, where we will give it our all."

Commonwealth champion Lisa Dobriskey, fourth in the Olympics last year, qualified for Sunday's final of the women's 1,500m after timing her semi-final to perfection.

The 25-year-old from Kent said: "I'm really pleased, I really wanted to make the final. Just to be here is such a big achievement for me, but you always want that bit more, you always want to achieve your potential.

"In the past I would have been really grateful to make the final, but now it's sort of expected. I like to think I can win a medal. My performances and training have really come together, I've got that fitness back and I'm able to string sessions together consecutively."
