Keely Hodgkinson took silver in one of the races of the World Championship - and was unable to hide her disappointment.
Britain’s 800 metres star came to Oregon intent on upgrading her Olympic silver medal, only to again be denied by Athing Mu.
The two 20-year olds fought a battle royal over two laps of a packed Hayward Field before Hodgkinson edged ahead in the final 100m.
It seemed she had cracked the Olympic champion, but Mu dug deep and pulled back level before grabbing gold on the dip.
A downcast Hodgkinson said: “It was a great race, one of the races of the championship and I’m grateful be a part of it, but I’m obviously gutted.
“I can't dwell on it too much. In a week I go for the Commonwealths so I've got to get myself sorted for that, but I'm definitely a little bit annoyed.”
Hodgkinson’s silver meant Britain finish the championships with seven medals, most notably Jake Wightman’s 1500m gold.
There were bronze medals for Laura Muir (women’s 1500m), Matt Hudson-Smith (men’s 400m), Dina Asher-Smith (women’s 200m) and the men’s sprint and women’s one lap relays.
Britain’s final tally was their best since 2013. But it was also the first time since Osaka in 2007 that they failed to pick up at least two golds, and that dropped them down to 11th in the medal table.
The final day of competition brought two world records with pole vault king Mondo Duplantis clearing 6.21m - a colossal 27cms ahead of second place.
Earlier, Nigeria’s Tobi Amusan clocked 12.12secs to win the women’s 100m hurdles. Britain’s Cindy Sember was fifth in the final but had the consolation of breaking her sister Tiffany Porter’s national record in 12.50.
