Great Britain's women's 4x100m relay team have raced into the final at the World Championships in Moscow.
The young quartet of Dina Asher Smith, Ashleigh Nelson, Annabelle Lewis and Hayley Jones clocked 42.75 seconds to initially finish second to the Bahamas.
The winners were soon disqualified, though, for running out of lane, elevating Britain to first.
It represents a big improvement from last year when the hosts did not even have a women's sprint relay squad at London 2012.
The United States were the fastest qualifiers in 41.82secs.
The men's team looked impressive as they took the scalp of the Jamaicans to win their semi-final.
The caveat was that there was no Usain Bolt in the Jamaican quartet - he will come in for the final - but the British four of Richard Kilty, Harry Aikines Aryeetey, James Ellington and Dwain Chambers still clocked a season's best 38.12s.
And this was not Britain's strongest line-up either. Adam Gemili, the 200m finalist, will likely come in for Kilty for the final tonight.
James Dasaolu is not in the team, because his injuries in the build-up to the championships left him unavailable for practice.
Most importantly, there were no baton blunders for which Britain have become so infamous in recent years.
Ellington said on BBC One: "We will do well and if we get the baton round, which we will, then we will get a medal."
The US survived a very shaky final changeover to go through fastest in 38.06.
