Great Britain's Shara Proctor came agonisingly close to winning World Championship gold for the first time in the women's long jump, but eventually had to settle for second-place following an enthralling battle with American Tianna Bartoletta in Beijing.
Anguillan-born Proctor, who finished fourth at the Commonwealth Games last summer, broke her own national record with a leap of 7.07m to position herself at the head of the pack and narrowly passed the 7m mark once again before being pipped to the line with a massive jump of 7.14m from the 2005 champion.
Lorraine Ugen finished a respectable fifth, but it was another testing evening for Katarina Johnson-Thompson at the Bird's Nest Stadium. Looking to recover from a disastrous heptathlon effort during which she fell dramatically from medal contention with three consecutive fouls in the long jump before having to complete a meandering 800m, the 22-year-old could only manage two efforts at 6.63m to end up in 11th place.
After her latest disappointment, she told BBC Sport: "It's such an amazing competition and I crave events like this. I'm really disappointed not to be in the final-eight but I gave everything I could. I don't know why this has been sent to test me, this has been one of the worst weeks of my life, but hopefully I can bounce back next year."
Elsewhere on day seven, starlet Dina Asher-Smith did not manage to claim a medal in an extremeley quick women's 200m final but still managed a new British record of 22.07 seconds to finish fifth.
Dafne Schippers took gold with the third-fastest time in history behind Florence Griffith Joyner and Marion Jones, outsprinting Jamaican pair Elaine Thompson and Veronica Campbell-Brown on the final straight.
Despite a strong start, Tiffany Porter finished fourth in the 100m hurdles, behind Danielle Williams, Cindy Roleder, Alina Talay and Brianna Rollins. Sister Cindy Ofili sadly did not qualify.
