Sharp falls at semi-final hurdle
Scotland's Lynsey Sharp, the subject of Britain's biggest athletics selection controversy, has failed to make the Olympic final of the women's 800 metres.
After qualifying well from the heats she was only able to finish seventh in Thursday night's first semi-final in two minutes 01.78 seconds, more than a second outside her personal and season's best.
A disappointed Sharp said: "My aim was to make the semis but I also thought I could have run a PB here, but neither of the races were ran in a way that was a PB race. I guess I got half my goal. The race wasn't really run how I expected."
She added: "I found myself at the front in the first lap. I run better chasing people. I just didn't run well in the first lap and up the back straight I was trying to make a move and there was a line of people four lanes wide. I had no path to get through and I ran out of room down the home straight."
Sharp's semi-final was won by defending Olympic champion Pamela Jelimo, but former world champion Caster Semenya was the fastest qualifier in 1:57.67, a season's best for the South African.
Meanwhile, Britain reached the final of the men's 4x400m relay after impressive displays from Jack Green and Martyn Rooney.
The 20-year-old Green made a storming finish to the third leg to give anchor runner Rooney a narrow lead. Rooney held that lead until easing up just before the line, allowing Trinidad and Tobago to take first place, although both teams were given the same time of three minutes 00.38 seconds to qualify automatically for the final.
The Bahamas and the United States were also given the same time of 2mins 58.87secs in the second semi-final to qualify quickest, but any faint hopes of Usain Bolt appearing in the 4x400m final were ended when Jamaican team-mate Jermaine Gonzales pulled up injured on the third leg.
