Great Britain's Cindy Ofili has insisted that she can "only be happy with fourth place" in the women's 100m hurdles final.
Ofili missed out on a medal by two hundredths of a second as USA's Brianna Rollins claimed gold, but the British representative has said that she was pleased to have played her part in a competitive race.
The 22-year-old told BBC Sport: "I came out here to try and get a medal for GB. It was a great race. I can only be happy with this performance. I have had an off-and-on year so I am just happy to almost get a medal."
Ofili's elder sister Tiffany Porter finished in seventh position.
